When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 15.6 g of carbon were burned in the presence of
NeX [460]

Answer: 5.72 g mass of carbon dioxide was produced

Explanation:

C+O_2\rightarrow CO_2

Moles of C =\frac{\text{mass of carbon}}{\text{molar mass of carbon}}=\frac{15.6 g}{12 g/mol}=1.3 moles

Mass of O_2 reacted = 59.1 g - 17.5 g = 41.6 g

Moles of O_2\text{ reacted}=\frac{\text{mass of}O_2}{\text{molar mass of}O_2}=\frac{41.6 g}{32 g/mol}=1.3 moles

According to reaction 1 mole O_2 produces 1 mole of CO_2 then 1.3 mole of O_2 will produce \frac{1}{1}\times 1.3 moles of CO_2

Mass of CO_2:

=Moles of CO_2 × molar mass ofCO_2 = 1.3 ×44 g/mol =

=57.2 grams

5.72 g mass of carbon dioxide was produced
