Answer:0.026ml
Explanation:
Details are found in the image attached. We must subtract the saturated vapour pressure of hydrogen gas at the given temperature from the total pressure of the hydrogen gas collected over water to obtain the actual pressure of hydrogen gas and substitute the value obtained into the general gas equation. The dry hydrogen gas has no saturated vapour pressure hence the value is substituted as given. All temperatures must be converted to Kelvin before substitution.
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g) (option A).
<h3>What is a balanced equation?</h3>
A chemical equation is said to be balanced when the number of atoms of each element on both sides of the equation is the same.
According to this question, the chemical equation between nitrogen and hydrogen is given as follows: N₂(g) + H₂(g) → NH3(g)
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g).

Answer:
A. an equal and opposite reaction force
Explanation:
This means that there is a natural reaction of force
Answer:
<u>B</u> What role do animals have in the carbon cycle?
Group of answer choices
use water and release oxygen
<u>use sugar and release carbon</u>
use carbon and release oxygen
use carbon and release nitrogen
<u>D, E</u> Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.
Group of answer choices
There is more available space for carbon to become fossil fuels.
There is less carbon in storage.
There will be less carbon in the water.
<u>There is more carbon in the atmosphere.</u>
<u>There will be more carbon respired by organisms.</u>
There will be less carbon released through decomposition.
Explanation:
Animals obtain energy through sugar from the food they eat and release carbon into the air through respiration. Therefore, they partake in the carbon cycle by using sugar and releasing energy.
As far as the second question, when fossil fuels are burned, the carbon contained within them is released into the atmosphere in the form of carbon dioxide. So, there will obviously be a greater amount in the atmosphere.
I would like to apologise in advance if either of my option choices were incorrect.
