When 3.0 g of carbon is burnt in 8.00 g 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 combinations will govern your answer?

(a) State the postulate of dalton’s atomic theory which can explain the above law.

(b) State the postulate of dalton’s atomic theory which can explain the law of conservation of mass.

carbon + oxygen = caron dioxide

3.00g + 8.00g = 11.00g

now if oxygen is increased upto 50.00g

so, let the chemical combination be X g

3.00g + 50.00g = X g

therefore, X = 11.00 g

because, 8.00 g of can react with 3.00g of carbon

so, if carbon remains same then the oxygen will also be same...

rest of 42.00g will be wasted .

sorry dear friend i am not knowing the part (a) & (b) currently but hope the othe helps u :)

Part-I
The answer is govern by the the law of definite proportions.

Reason : 3.0 g of carbon combines with 8.0 g of oxygen to give 11.0 of carbon dioxide.Now, same amount of 3.00 g of carbon is burnt in 50.00 g of oxygen, only 8.00 g of oxygen will be used and again their is production of only 11g of carbon dioxide. The remaining 42.00 g of oxygen will remain as is. So, The answer is govern by the the law of definite proportions.

Part : II

(a)State the postulate of dalton’s atomic theory which can explain the above law.
(b) State the postulate of dalton’s atomic theory which can explain the law of conservation of mass

Answer 2

when 3.00 g of carbon is burnt in 8.00g of oxygen then the mass of carbon dioxide formed =11.00g

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

3.00g +8.00g =11.00g

SO LIKEWISE

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
