Answer: 3.00 molecules
Explanation:
Given that:
Mass of CO2 = 132.03 grams
Number of molecules of CO2 = ?
Molar mass of CO2 = ?
For the molar mass of CO2: Atomic mass of Carbon = 12; Oxygen = 16
= 12 + (16 x 2)
= 12 + 32 = 44g/mol
Apply the formula:
number of molecules = (mass in grams/molar mass)
N = (132.03 grams/44g/mol)
N = 3.00 molecules
Thus, there are 3.00 molecules of CO2 in 132.03 grams of CO2.

<h2>Answer:</h2>
<u>The correct answer is Thermal Energy</u>
<h2>Explanation:</h2>
Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. Since the matchstick produces heat energy and heat is referred o thermal energy so it is the correct answer.
