Question

If 3g of carbon burns in 8g oxygen to produce 11g of carbon dioxide. Then how much carbon dioxide will be produced if 12g of carbon is burnt in 32g if oxygen? Which law of chemical combination will govern your answer?

Answer 1

Answer:

44g CO2

Explanation:

3g carbon+ 8g oxygen= 11g carbon dioxide

therefore,

4(3g carbon+8g oxygen)=4×11g carbon dioxide

=12g carbon+32g oxygen=44g carbon dioxide

[law of proportion]
