When carbon is burned in air, it reacts with oxygen to form carbon dioxide. when 27.6 g of carbon were burned in the presence of 89.6 g of oxygen, 16.0 g of oxygen remained unreacted. what mass of carbon dioxide was produced?

101.2 g of carbon dioxide was produce.

Explanation:

Given data:

mass of mass of carbon = 27.6 g

mass of oxygen = 89.6 g

mass of unreacted oxygen = 16 g

mass of carbon dioxide produced = ?

Solution:

To solve this problem first of all we will calculate the mass of oxygen that reacted.

mass of reacted oxygen = total mass - unreacted mass

mass of oxygen= 89.6 g - 16 g

mass of oxygen= 73.6 g

mass of carbon dioxide produced = mass of oxygen + mass of carbon

mass of carbon dioxide produced = 73.6 g + 27.6 g

mass of carbon dioxide produced = 101.2 g

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
