Answer:
Pretty sure the answer is B
The pressure of hydrogen gas formed is 720.8 mmHg.
<h3>What is Partial Pressure ?</h3>
The pressure exerted by a (specified) component in a mixture of gases.
We have to understand one thing that the Hydrogen, which is collected over water, will be mixed with water vapor.
This means that the total pressure of the mixture will have two components.
- the partial pressure of Hydrogen
- the vapor pressure of water at 21.5 C
The vapor pressure of water at that temperature is approximately
19.231 mmHg.
This means that
740 = 
+ 19.231
= 740-19.231
= 720.8 mmHg
Therefore the pressure of hydrogen gas formed is 720.8 mmHg.

Answer:
The correct answer is - cellular respiration is when <u><em>chemical</em></u> energy from sugar/glucose is converted to cellular <u><em>energy in the form of ATP</em></u><em><u>.</u></em>
Explanation:
Cellular respiration is a set of metbolic reaction that takes place inside the cell and breaking the sugars or nutrients to convert the chemical energy present in the nutrients into the cellular energy whic is used by cells that is ATP and release water and carbon dioxide as waste.
In this process the ammount of energy store in the cellular currecncy or ATP which is the form of energy that is utilized by the to perform its sunction. The chemical energy that is present in the nutrients or sugar is come from light energy which is stored in the nutrients by photosyntheis process.
Homogeneous mixture made up of two or more substances
Answer:
Solution
Explanation:
An homogenous mixture made up of two or more substances is called a Solution.
Solutions are homogenous mixtures of solutes and solvents.
- In a solution, the solute particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- It is usually present in smaller amount than the solvent
- The solvent is the dispersing medium which allows for the solute to go into solution.
