Suppose 12.0 g of silicon (Si) reacts with 70.0 g of oxygen (O 2 ) to give

Question:

Suppose 12.0 g of silicon (Si) reacts with 70.0 g of oxygen (O₂) to give 25.6 g of the compound silicon dioxide (SiO₂). In the process, all the silicon gets used up, but some oxygen is left over.

(a) For the law of conservation of matter to be obeyed, how much oxygen is unused?

(b) What is the percent Si in SiO₂?
