When 3.00 g of carbon is burnt in 8,00 g of oxygen, 11.00 g of carbon dioxide is produced. What mass of carbon dioxide will be formed when 3.00 g of carbon is burnt in 50.00 g of oxygen? Which law of chemical combination will govern your answer ? |

Answer» Solution :`"CARBON + Oxygen" to "Carbon dioxide"` `C + O_(2) to CO_(2)` `12g + 32 g to 44 g` `:.` 3g of carbon BURNS in 8 g of oxygen producing 11 g of carbon dioxide. So, when there is 3.00 g of carbon and 50.00 g of oxygen, then also only 8G of oxygen will be used forming 11.0 g of carbon dioxide. 42 g of oxygen (50 g-8g) will remain unused. The answer is GOVERNED by the law of constant proportion. |
