Looking at the chemical reaction above, 32 grams of Oxygen gas combine with an unknown amount of Carbon to produce 44 grams of Carbon dioxide when heat is added. What is the unknown amount of carbon in this chemical reaction?

12 g of C.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

O2 + C —> CO2

Finally, we shall determine the mass of O2 and C that reacted. This can be obtained as follow:

Molar mass of O2 = 16 × 2 = 32 g/mol

Mass of O2 from the balanced equation = 1 × 32 = 32 g

Molar mass of C = 12 g/mol

Mass of C from the balanced equation = 1 × 12 = 12 g

Thus, from the balanced equation above, 32 g of O2 reacted with 12 g of C.
