How many liters of bromine are needed to produce 12 miles of aluminum bromide?

Answer:

The answer is B.

Explanation:

Ethical concerns affect scientific research when scientists or groups of scientists let their personal bias or political persuasions affect the research being conducted. Scientific ethics involve doing experimentation and analysis of data without bias no matter what the conclusions point to.

Ethical principles dictate that researchers have a responsibility to ensure that their work does not cause harm to human beings, animals, or the environment. The correct answer is B. Scientists should not be allowed to conduct research that is harmful to others.

Research involving human subjects, for example, must adhere to strict ethical guidelines, such as informed consent and minimizing risks. Ethical review boards or committees often evaluate research proposals to ensure that potential harm is minimized or avoided.

Ethics significantly affect scientific research by guiding researchers to conduct their work responsibly, ensuring the well-being of individuals and society, and addressing potential conflicts between scientific advancement and ethical principles.

Therefore, the correct answer is B. Scientists should not be allowed to conduct research that is harmful to others.

Answer:

Radius of the steel ball is 4.6mm

Explanation:

Hello,

To find the radius of the steel, we'll have to calculate it from it's volume which can be gotten from the density of the material.

Data;

Mass = 3.25g

Density = 7.86g/cm³

Density = mass / volume

Volume = mass / density

Volume = 3.25 / 7.86

Volume = 0.413cm³

Volume of a steel = 4/3πr³

0.413 = 4/3 × π × r³

0.413 = 1.33 × 3.14 × r³

0.413 = 4.1762r³

r³ = 0.413 / 4.1762

r³ = 0.099

Take the cube root of both sides

r = 3√(0.099)

r = 0.46cm

From metrics table

1cm = 10mm

0.46cm = x mm

x = (0.46 × 10)

x = 4.6mm

The radius of the steel ball is 4.6mm

Step 2: Identify Conversions

Molar Mass of Cd - 112.41 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of Cd₃N₂ - 3(112.41) + 2(14.01) = 365.25 g/mol

Step 3: Convert

[tex]\displaystyle 1.450 \ mol \ Cd_3N_2(\frac{365.25 \ g \ Cd_3N_2}{1 \ mol \ Cd_3N_2} ) = 529.613 \ g \ Cd_3N_2[/tex]

Answer:

The electrons are found on the atomic nucleus.

Explanation:

Answer:

0.5 M

Explanation:

First we have to start with the molarity equation:

[tex]M=\frac{mol}{L}[/tex]

We need to know the amount of moles and the litters.

If we have 100 mL we can convert this value to “L”, so:

[tex]100~mL\frac{1~L}{1000~mL}[/tex]

[tex]0.1~ L[/tex]

Now we can continue with the moles, for this we have to know the formula of sodium sulfate [tex]Na_2SO_4[/tex], with this formula we can calculate the molar mass if we know the atomic mass of each atom on the formula (Na: 23 g/mol, S: 32 g/mol, O: 16 g/mol). We have to multiply each atomic mass by the amount of atoms in the formula, so:

[tex]molar~ mass~=~ (23*2)+(32*1)+(16*4)= ~ 142~ g/mol[/tex]

In other words:

[tex]1~mol~ Na_2SO_4=~142~g~ of~Na_2SO_4[/tex]

Now we can calculate the moles:

[tex]7.1~g~ of~Na_2SO_4\frac{1~mol~ Na_2SO_4}{142~g~ of~Na_2SO_4} [/tex]

[tex]0.05~mol~ Na_2SO_4 [/tex]

Finally, we can calculate the molarity:

[tex]M=\frac{0.05~mol~ Na_2SO_4 }{0.1~ L}[/tex]

[tex]M=0.5[/tex]

I hope it helps!

Answer:

0.50M of solution

Explanation:

Molarity is defined as the ratio between moles of solute (In this case, sodium sulfate, Na₂SO₄) per liter of solution.

Moles of 7.1g of Na₂SO₄ (Molar mass: 142g/mol) are:

7.1g Na₂SO₄ × (1mol / 142g) = 0.05 moles of Na₂SO₄.

In 100mL = 0.100L:

0.05 moles Na₂SO₄ / 0.100L = 0.50M of solution

Answer:

0.93L

Explanation:

We'll begin by calculating the number of mole of present 374g of KNO3. This is illustrated below:

Mass of KNO3 = 374g

Molar mass of KNO3 = 39 + 14 + (16x3) = 101g/mol

Number of mole of KNO3 =..?

Mole = Mass /Molar Mass

Number of mole of KNO3 = 374/101 = 3.7 moles

Now, we can calculate the volume of the solution as follow:

Mole of KNO3 = 3.7 moles

Molarity = 4M

Volume =..?

Volume = mole /Molarity

Volume = 3.7/4

Volume = 0.93L

Therefore, the volume of the solution is 0.93L

Answer:

THE VOLUME OF A 4 M SOLUTION THAT CONTAINS 374 g OF KNO3 IS 0.93 L

Explanation:

Number of moles = concentraion * volume

Number of moles can also be written as:

number of moles = mass / molar mass

Calculate the molar mass of KNO3 where (K = 39, N = 14, 0=16)

molar mass of KNO3 = (39 + 14 + 16*3) = 101 g/mol

So therefore:

mass / molar mass = concentration * volume

where;

mass = 374 g

molar mass = 101 g/mol

concentration = 4 M

volume = unknown

Hence,

374 / 101 = 4 * V

V = 374 / 101 * 4

V = 374 / 404

V = 0.9257 dm3

The volume of a 4M solution that contains 364 g of KNO3 is approximately 0.93 L

Answer:

Phenol reacts with formaldehyde to form Phenol-formaldehyde resins  which is used to make plastic bakelite. Phenol-formaldehyde resins are made through a step-growth polymerization reaction.

equation of polymerization reaction in which Phenol (HOC6H5) reacts with formaldehyde (CH2O) is as following:

1. HOC6H5 + CH2O =>  HOC6H4CH2OH (hydroxymethyl phenol)

hydroxymethyl phenol then reacts with another hydroxymethyl group in next two steps and form methylene bridge (at firs) and ether bridge (secondly)

2. HOC6H4CH2OH + HOC6H5  => (HOC6H4)2CH2 + H2O

3. 2 HOC6H4CH2OH => (HOC6H4CH2)2O (bisphenol F) + H2O

Bisphenol F is the the diphenol (HOC6H4)2CH2 that is formed as the result and used to produce epoxy resins.
