Use your balanced reaction to make a "for every" statement for magnesium and hydrogen gas in this reaction. For every 1 mole of magnesium, the reaction makes 1 mole of hydrogen gas.

For every 1 mole of magnesium, the reaction makes 2 moles of hydrogen gas.

For every 24.305 mole of magnesium, the reaction makes 2.016 mole of hydrogen gas.

For every 1 mole of magnesium, the reaction uses up 1 mole of hydrogen gas.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

it should be all of them because it asks if you included all of those in your answer

explanation:
