Question

When 3.0 g of carbon is burnt in 8.00 g oxygen, 11.00 g of carbon dioxide is Droduced. What mass of carbon dioxide will be formed when 3.00 g of carbon is burnt in 50.00 g of oxvgen? Which law of chemical combination will govern your answer?

Answer 1

when 3.00 g of carbon is burnt in 50.00g of oxygen then the mass of carbon dioxide formed =53.00g

according to the law of conservation of mass the total mass before and after the reaction remains same.

3.00g +50.00g =53.00g

Answer 2

Answer:

53g and law of constant proportion,

Explanation:

The above reaction will be following the law of constant mass proportion which states that the mass in the reactant side will be same as the total mass in the product side.

So, from the first equation we will get that C+O2->CO2 where reactant mass (3+8)=product mass(11).

Again for the next equation we will have C+2O2 -> CO2 +O2 in which the masses will be 3+50 which will be equal to 53g which will also be the mass of the product.
