The required speech is as follows :
_______________
"Whoever controls media, controls mind". A very hearty Good Morning to one and all present here ! Respected Principal Sir, worthy teachers and all my dear fellow mates. Today I Aurora, of class XYZ is standing before you in this frizzy winter to deliver a short speech on the topic 'How media influences public opinion'.
Dear friends, first of all I would like to ask you all a question, 'What do you think is our media for ?' Most of us will reply that they are for our entertainment, fun and even unfortunately some will reply 'for movies and Bollywood'. Now if we look back at our history during 18th century we see that even first newspapers were started for spreading information in mass. Earlier literacy rate of India was very low.
A single person used to first read the newspaper and then shared the information to the gathered people around. But that time was different. Now nearly every person has a mobile phone, TV, PC and what not. Has this increased public participation in Democracy ? Yes indeed it has done that. On one single click we get information of our surrounding at a faster pace. As a fourth pillar of Democracy it makes our mindful of different social, political and financial exercises around us.
If we take current situation, most of the election popularisation works in different states is being managed by mass media only due to its advancements. Media makes participation of people in political activities even at grass - root levels. This efficiency enhances the Federalism of India. Media has many roles in shaping public opinion in our society. Let's discuss them one by one. In economic terms, media shows the expenditure, budgets and taxes to the citizens of a nation.
It makes people aware of the different types of money related issues that they have to face. Even it checks that no people are harassed by fake news on balances. Its makes people rise over their concern directly to the government so that actions can be taken for them. In social terms, media promotes the functioning of the government. It helps people to convey their social problems to the government. Even many NGOs and Human Rights Organizations take help of medias to make people aware of their rights.
Commonly Media acts as an inference or better to say 'compass' which gives direction to the views of people. It organises the vast multitudes of opinions into a single issue which can be beneficial to all the groups of society. It works 24 × 7 and makes people get in touch with latest developments. As 'Opposition' in Politics, media acts as a hub where the opposition party by taking views of public claims the wrong decisions of Ruling Party.
Also, during elections media shows mirror about different parties to people so that we can make right decision in voting. All these were some positive aspects of media's influence on public opinions. Now let's discuss about some negative aspects also. Nowadays its a common seen trend that media enlarges a short issue just to gain popularity. This results in riots, violence, protests, etc. because the issue which could have been solved by a single subtle discussion, now has been made a larger issue.
Let me present an example. I have a friend, Cupicake. She remains quite much familiar with medias. Some days ago, she received a post which asked her to share the image attached with it to her other friends. That image was of a case where Police was beating a few groups of people. She has shared that. This led a immediate violence in that region and finally it was known that Police was beating a few robbers. Now who to put blame of that riot ? Of course we are the one who done it.
At last I would like to conclude my speech by just saying that, it is the duty of media to transfer right and reliable information to people and its duty of people to share and trust upon right information from a good source. In this way the world and the nation would be leaded to right path.
Thank you one and all.

Give the hybridization for the C in HCN
Answer:
[tex]\huge\boxed{sp \ hybridization}[/tex]
Explanation:
In HCN,
Carbon is singly - bonded ( 1 sigma bond ) to Hydrogen while triply - bonded ( 1 sigma, 2 pi bonds) to Nitrogen.
Thus, the Stearic No. for Carbons is:
= No. of sigma bonds + No. of lone pairs
= 2 + 0
= 2
According to Stearic No.:
=> sp = 2
=> sp² = 3
=> sp³ = 4
Hence,
The hybridization of C in HCN is sp.

A heat engine with 0.500 mol of a monatomic ideal gas initially fills a 3000 cm3 cylinder at 800 K. The gas goes through the following closed cycle: - Isothermal expansion to 4000 cm3. - Isochoric cooling to 300 K. - Isothermal compression to 3000 cm3. - Isochoric heating to 800 K.
Answer:
Explanation:
[tex]\text{For isothermal expansion:}[/tex]
[tex]W_1 = nRT_1 In (\dfrac{V_2}{V_1}) \\ \\ W_1 = 0.5 \times 8.314 \times 800 \times In (\dfrac{4000}{3000})\\ \\ W _1 = 956.72 \ J \\ \\ Q_1 = W_1 = 956.72 \ J \ since \ (dU=0) \\ \\ \\ \text{For isochoric cooling,} W_2 = 0} \\ \\ Q_2 = nCr \Delta T \\ \\ Q_2 = 0.5 (\dfrac{3R}{2})(T_2-T_1) \\ \\ Q_2 = 0.5 \times \dfrac{3\times 8.314}{2}(-500)= -3117.75[/tex]
[tex]\text{For Isothermal compression:}\\\\ W_3 = nRT_2 \ In (\dfrac{V_4}{V_3}) \\ \\ 0.5 \times 8.314 \times 300 \times In (\dfrac{3000}{4000}) \\ \\ W_3 =- 358.77 \ J \\ \\ Q_3=W_3= - 358.77 \ J[/tex]
[tex]\text{For isochoric heating; }W_4 =0} \\ \\ Q_4 = nC_v\Delta T \\ \\ = 0.5 \times \dfrac{3}{2}\times 8.314 \times 500 \\ \\ Q_4 = 3117.5 \ J[/tex]
[tex]\text{Total workdone W}= W_1 + W_2+W_3+W_4 \\ \\ W = 956.71 \ J + 0 + (-358.77 \ J) +0 \\ \\ \mathbf{W = 597.94 J} \\ \\ \\ \eta = \dfrac{Work \ done}{heat \ taken } \\ \\ \eta = \dfrac{W}{Q_1+Q_4} \\ \\ \eta = \dfrac{597.94 \ J}{956.71 \ J + 3117.5 \ J} \\ \\ \eta = 0.1468 \\ \\ \mathbf{\eta = 14.68\%}[/tex]
A sample of aluminum, which has a specific heat capacity of 0.897·J·g−1°C^−1 , is put into a calorimeter (see sketch at right) that contains 300.0g of water. The aluminum sample starts off at 94.5°C and the temperature of the water starts off at 21.0°C .When the temperature of the water stops changing it's 23.8°C .The pressure remains constant at 1atm .Calculate the mass of the aluminum sample.
Answer: The mass of aluminium sample is 55.4 gram
Explanation:
[tex]Q_{absorbed}=Q_{released}[/tex]
As we know that,
[tex]Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})[/tex]
[tex]m_1\times c\times (T_{final}-T_1)=-[m_2\times c\times (T_{final}-T_2)][/tex]
where,
[tex]m_1[/tex] = mass of aluminium = ?
[tex]m_2[/tex] = mass of water = 300.0 g
[tex]T_{final}[/tex] = final temperature = [tex]23.8^0C[/tex]
[tex]T_1[/tex] = temperature of aluminium = [tex]94.5^oC[/tex]
[tex]T_2[/tex] = temperature of water = [tex]21.0^oC[/tex]
[tex]c_1[/tex] = specific heat of aluminium = [tex]0.897J/g^0C[/tex]
[tex]c_2[/tex] = specific heat of water = [tex]4.184J/g^0C[/tex]
Now put all the given values in equation (1), we get
[tex]-[m_1\times c_1\times (T_{final}-T_1)]=[m_2\times c_2\times (T_{final}-T_2)][/tex]
[tex]-[m_1\times 0.897\times (23.8-94.5)^0C]=[300.0g\times 4.184\times (23.8-21.0)][/tex]
[tex]m_1=55.4g[/tex]
Therefore, the mass of aluminium sample is 55.4 gram

Describe how to prepare 100.00 mL of a 0.250 M sodium chloride (NaCl) solution using sodium chloride powder.
Answer:
The answer to your question is given below.
Explanation:
We'll begin by converting 100 mL to L. This can be obtained as follow:
1000 mL = 1 L
Therefore,
100 mL = 100 mL × 1 L / 1000 mL
100 mL = 0.1 L
Next, we shall determine the number of mole of NaCl in the solution. This can be obtained as follow:
Volume of solution = 0.1 L
Molarity of NaCl = 0.250 M
Mole of NaCl =?
Molarity = mole / Volume
0.250 = mole of NaCl / 0.1
Cross multiply
Mole of NaCl = 0.250 × 0.1
Mole of NaCl = 0.025 mole
Finally, we shall determine the mass of 0.025 mole of NaCl. This can be obtained as follow:
Mole of NaCl = 0.025 mole
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
Mass of NaCl =?
Mole = mass / Molar mass
0.025 = mass of NaCl /58.5
Cross multiply
Mass of NaCl = 0.025 × 58.5
Mass of NaCl = 1.46 g
Thus, to prepare the solution, weigh out 1.46 g of NaCl and dissolve in 1 L of water.
Describe the critical property ofelectrons in 2s versus 2p orbitals that causes the radial distribution functions of these orbitals to have different shapes about the nucleus such that 2s electrons effectively penetrate closer to the nucleus than do electrons in 2p orbitals.Then, write an expression for the potential energy function describing this effect.
Answer:
Answer is explained in the explanation section below.
Explanation:
Penetration refers to the proximity of electrons in an orbital to the nucleus.
Deeper-penetrating electrons have less shielding and therefore a higher Effective nuclear charge (Zeff), but they better shield other electrons.
To illustrate penetration, we may use the idea of Zeff, or effective nuclear charge. It's actually the difference between the number of charged protons and the number of shielded electrons. To put it another way, how effective the nucleus is at attracting electrons. Since they do not shield themselves, the core electrons penetrate the most and are exposed to the most strong nuclear charge.
The electron probability density is highest in the orbital's centre or nucleus for 28-orbitals.
In a multi-electron unit, the electron density near the nucleus of an atom for each shell and subshell of an electron is used to measure the nucleus penetration by an electron.
Since it has a higher electron density near the nucleus, the 2s electron penetrates the nucleus of the atom more than the 2p electron.
A 2s electron is less well shielded by the core electrons than a 2p electron because it can spend more time near the nucleus as a result of the penetration.
Mathematical Expression:
v = [tex]\frac{-Zeff * e^{z} }{r^{2} }[/tex]

For each of the following acid-base reactions,
calculate the mass (in grams) of each acid necessary
to completely react with and neutralize 3.65 g of the
base.
Part A
HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq)
Part B
2 HNO3(aq) + Ca(OH)2(aq)
2 H2O(1) + C
Answer: A. 3.28 g of HCl
B. 6.30 g of [tex]HNO_3[/tex]
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} NaOH=\frac{3.65g}{40g/mol}=0.09moles[/tex]
[tex]\text{Moles of} Ca(OH)_2=\frac{3.65g}{74g/mol}=0.05moles[/tex]
a) [tex]HCl(aq)+NaOH(aq)\rightarrow H_2O(l)+NaCl(aq)[/tex]
According to stoichiometry :
1 mole of [tex]NaOH[/tex] require = 1 mole of [tex]HCl[/tex]
Thus 0.09 moles of [tex]NaOH[/tex] will require=[tex]\frac{1}{1}\times 0.09=0.09moles[/tex] of [tex]HCl[/tex]
Mass of [tex]HCl=moles\times {\text {Molar mass}}=0.09moles\times 36.5g/mol=3.28g[/tex]
b) [tex]2HNO_3(aq)+Ca(OH)_2(aq)\rightarrow 2H_2O(l)+Ca(NO_3)_2(aq)[/tex]
According to stoichiometry :
1 mole of [tex]Ca(OH)_2[/tex] require = 2 moles of [tex]HNO_3[/tex]
Thus 0.05 moles of [tex]Ca(OH)_2[/tex] will require=[tex]\frac{2}{1}\times 0.05=0.1moles[/tex] of [tex]HNO_3[/tex]
Mass of [tex]HNO_3=moles\times {\text {Molar mass}}=0.1moles\times 63g/mol=6.3g[/tex]

Hey! I was wondering how to get the solution to this question!
A solution was prepared by dissolving 0.541 g of benzoic acid (HC6H5COO) in 100 mL of
water. The pH was measured to be 2.78. What is the Ka for benzoic acid?
Answer:
6.22 × 10⁻⁵
Explanation:
Step 1: Write the dissociation reaction
HC₆H₅COO ⇄ C₆H₅COO⁻ + H⁺
Step 2: Calculate the concentration of H⁺
The pH of the solution is 2.78.
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog -2.78 = 1.66 × 10⁻³ M
Step 3: Calculate the molar concentration of the benzoic acid
We will use the following expression.
Ca = mass HC₆H₅COO/molar mass HC₆H₅COO × liters of solution
Ca = 0.541 g/(122.12 g/mol) × 0.100 L = 0.0443 M
Step 4: Calculate the acid dissociation constant (Ka) for benzoic acid
We will use the following expression.
Ka = [H⁺]²/Ca
Ka = (1.66 × 10⁻³)²/0.0443 = 6.22 × 10⁻⁵

5. 1.250 g of an alloy which is 90.00 % Ag and 10.00 % Cu is reacted with nitric acid producing AgNO3 and Cu(NO3)2 dissolved in solution. To the solution of the nitrate compounds is added a piece of copper wire that reacts only with the AgNO3 in solution to precipitate all of the silver, and produce additional Cu(NO3)2 (aq) . (The equation for this single-replacement reaction is: AgNO3(aq) + Cu(s) Cu(NO3)2(aq) + 2 Ag(s) ) The resulting solution containing all of the Cu(NO3)2 produced by the above processes is treated with excess zinc to precipitate the entire amount of copper (ll) ion present. ( The equation for this step is Cu(NO3)2(aq) + Zn(s) Zn(NO3)2(aq) + Cu(s) ) What mass of copper will be precipitated?
Answer:
See explanation
Explanation:
According to the question Copper is obtained from the original alloy and the copper wire used to displace the silver.
So,
Mass of the copper from the original alloy: (10.00 % * 1.250 g) = 0.125 g
We now need to obtain the mass of the copper from the wire, then we consider how much silver is precipitated:
Mass of silver in the alloy; 90.00 % * 1.250 g = 1.125 g
So,
Amount of silver precipitated =
1.125 / 107.9 = 0.01043 mole
From the reaction equation, it takes two moles of silver to displace one mole of copper.
Hence, the amount of copper from the wire is: 0.01043 / 2 = 0.005213 mol
And a mass of 0.005213(63.55) = 0.3313 g
Total mass of copper= 0.125 + 0.3313 = 0.456 g
