Answer:

I don't really get your question but I think my answer relates to your question :)

Explanation:

Due to the high availability of sunlight, sea grass can get the sufficient light energy to carry photosynthesis and storage of energy.

Photosynthesis is a biochemical process by which green plants synthesis energy and in the leaves by the aid of light energy. Here, the light energy is converted to chemical energy.

Plants need sunlight for the light reaction of photosynthesis. In the absence of sunlight, they cant synthesis energy and the chlorophyll does not get active. They will grow towards sunlight.

The sea grass are getting sufficient light energy for the synthesis of energy. The energy storage molecules ie. ATP in sea grass will be synthesized in higher rate with the presence of sun shining.

Answer:

when the electron moves from the first orbit to the third it gains energy  but when it jumps from a higher energy orbit to a lower the energy is being radiated. So whihever is the higher energy you know what it is.

Explanation:

Answer: The concentration of hydrogen ions in the given solution is [tex]6.2 \times 10^{-4}[/tex].

Explanation:

Given : pH = 4.32

pH of a substance or solution is the negative logarithm of hydrogen ion concentration.

[tex]pH = - log [H^{+}][/tex]

Substitute the value into above formula as follows.

[tex]pH = - log [H^{+}]\\= - log (4.32)\\= 6.2 \times 10^{-4}[/tex]

Thus, we can conclude that the concentration of hydrogen ions in the given solution is [tex]6.2 \times 10^{-4}[/tex].

Answer:

two

Explanation:

Every observer would observe the same image location and every light ray would follow the law of reflection. Yet only two of these rays would be needed to determine the image location since it only requires two rays to find the intersection point.

Answer:  11.02 moles of Ag can be formed.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Cu=\frac{350.00g}{63.55g/mol}=5.51moles[/tex]

The balanced chemical equation is:

[tex]Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag[/tex]  

According to stoichiometry :

1 moles of [tex]Cu[/tex] produces =  2 moles of [tex]Ag[/tex]

Thus 5.51 moles of [tex]Cu[/tex] will produce=[tex]\frac{2}{1}\times 5.51=11.02moles[/tex]  of [tex]Ag[/tex]  

Thus 11.02 moles of Ag can be formed.

Answer: Atm

I took a test and got it right.

Water cannot dissolve all substances that are made from ionic bonds probably because some ionic bonds are too strong for the attractions of water molecules to pull them apart.

However, some ionic bonds formed from ions of elements are unable to be dissolved by water and this is probably attributed to the fact that those bonds are too strong to be pulled apart by water molecules.

Answer: 1 molar NaOH contains 40 grams of NaOH per every liter of water

Explanation:

so 2 M NaOH contains twice that amount, ie. 80 grams per liter. Then, ine 250 ml of weater, there should be 80/4 = 20 grams of solid NaOH dissolved.

Answer:

176 g/mol

Explanation:

To get this, multiply the weight of the molecule by Avogadro's number:

(2.93×[tex]10^{-22}[/tex]) × (6.022×[tex]10^{23}[/tex]) = 176.44 g/mol

Answer:

it improves the accuracy of the results

Answer:

29.4mol

Explanation:

Using mole = mass ÷ molar mass

Molar mass of HF (hydrogen fluoride) = 1 + 19 = 20g/lol

Using the formula;

Mole = mass/molar mass

Mole = 588/20

Mole = 29.4mol

Answer:

7500 mmHg

Explanation:

From the question,

Applying Boyles Law,

PV = P'V'................ Equation 1

Where P = original pressure, P' = final pressure, V = Original Volume, V' = Final Volume.

make P' The subject of the equation

P' = PV/V'.............. Equation 2

Given: P = 650 cm³, P = 750 mmHg, V' = (650×10/100) = 65 cm³ (Reduced by 10 percent of it original volume)

Substitute these values into equation 2

P' = (650×750)/65

P' = 7500 mmHg

1.Exhaust from farming machines pollutes the air

2.Cows give off methane gas that gets into the atmosphere

3.The land the farm was cleared away on effects other recosystems

Explanation:

Farming adversely affected the earth systems such as climate change, deforestation, biodiversity loss, irrigation problems, pollutants, soil degradation, and waste production.

Agriculture causes a number larger of environmental issues that cause environmental degradation such as climate change, deforestation, biodiversity loss, irrigation problems, pollutants, soil degradation, and waste production.

For example, exhaust from farming machines pollutes the air, Cows give off methane gas that gets into the atmosphere and the land the farm was cleared away on effects other ecosystems.

So we can conclude that farming adversely affected the earth systems such as climate change, deforestation, biodiversity loss, irrigation problems, pollutants, soil degradation, and waste production.

(17.0 g N2) / (28.02 g/mol N2) = 0.607 moles N2

Convert to moles of NH3:

(0.607 moles N2)(2 moles NH3 / 1 mole N2) = 1.213 moles NH3

Convert to grams of NH3:

(1.213 moles NH3)(17.03 g/mol NH3) = 20.66 g NH3

Explanation:

To calculate the heat released in the reaction, we use the formula-

Q = m×c×Δt

Where

Q - The heat energy

m - the mass of the object/substance being heated

c - the specific heat of the object/substance being heated

Δt -  the change in temperature in °C
