Answer: When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

Add all the values for the volume added then divide by 3 because there are three values
D: the composition of the materials that make up the planet
<u>Answer:</u> 6 moles of 
will be decomposed.
<u>Explanation:</u>
We are given:
Moles of oxygen gas produced = 9 moles
The chemical equation for the decomposition of follows:
By the stoichiometry of the reaction:
If 3 moles of oxygen gas is produced by 2 moles of
So, 9 moles of oxygen gas will be produced by = 
of
Hence, 6 moles of will be decomposed.
