Question

12gof carbon burnt in 32g of oxygen to form 44g of co2 what mass of carbon dioxide will be formed when 6g of carbon is burnt in excess of oxygen ?​

Answer 1

Explanation:

Considering that 1 atom of carbon reacts with 2 atoms of oxygen;

Considering that 1 dozen atoms of carbon reacts with 2 dozen atoms of oxygen;

Considering that a mole is a number in the same way that a dozen is a number;

Considering 1 mole of carbon atoms reacts with 2 moles of oxygen atoms;

Considering that 1 mole of carbon atoms is 12 grams and 2 moles of oxygen atoms is 32 grams

THEN 12g C + 32g O = 44 g CO₂
