The answer is 3.10 because it's still the same amount moles of iron.
The statement that best describes the variables in a controlled experiment is independent variable while all other conditions are unchanged.
<h3>What is an experiment?</h3>
An experiment is a scientific research, findings or investigation about a subject matter with the aim of validating a claim and establishing theories.
A controlled experiment refers to an experiment in which the variables involved and the control factor are kept in the same group except for one variable which can be changed.
Therefore, The statement that best describes the variables in a controlled experiment is independent variable while all other conditions are unchanged.

Answer:
To find the volume of the gas. So if you have the amount of gas in moles. So the first step is to multiply the amount of moles that is 2.4 with liters to find the answer.
Explanation:
Answer : The total mass of oxygen gas released in the reaction will be, 12.8 grams
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of 
= Total mass of 
or,
Total mass of = Mass of 
+ Mass of 
As we are given :
Total mass of 
= 16.12 grams
The mass of 
= 9.72 grams
So,
Total mass of = Mass of + Mass of
Therefore, the total mass of oxygen gas released in the reaction will be, 12.8 grams
