1.) Mass

2.) Can occupy space (Volume)

**Answer:**

2nd one In my opinion....

**Answer:**

**Mass = 15.20 g of KCl**

**Explanation:**

The balance chemical equation for the decomposition of KClO₃ is as follow;

2 KClO₃ = 2 KCl + 3 O₂

**Step 1: **Calculate moles of KClO₃ as;

Moles = Mass / M/Mass

Moles = 25.0 g / 122.55 g/mol

Moles = 0.204 moles

**Step 2: **Find moles of KCl as;

According to equation,

2 moles of KClO₃ produces = 2 moles of KCl

So,

0.204 moles of KClO₃ will produce = **X** moles of KCl

Solving for **X**,

** X** = 2 mol × 0.204 mol / 2 mol

** X** = 0.204 mol of KCl

**Step 3: **Calculate mass of KCl as,

Mass = Moles × M.Mass

Mass = 0.204 mol × 74.55 g/mol

**Mass = 15.20 g of KCl**

**Answer:**

If one astronaut used more force, then that one would be faster than the other. The independent variable is force. The dependent variable is speed.

**Explanation:**

Force is what is to be changed. Speed is what is being measured.

IV = Changed/factor DV=Measured/Changes by factor
