When 5g of calcium is burnt in 2g of oxygen, then 7 g of calcium oxide is produced. What mass of calcium oxide will be produced when 50g of calcium is burnt in 20 g of oxygen ? Which law of chemical combination will govern your answer ?
When 5g of calcium is burnt in 2g of oxygen, then 7 g of calcium oxide of produced. What mass of calcium oxide will be produced when 5g of calcium is burnt in 20 g of oxygen ? Which law of chemical combination will govern your answer ?
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 combination will govern your answer?
Calcium carbonate decomposes, on heating , to form calcium oxide and carbon dioxide. When 10 g of calcium carbonate is decomposed completely, then 5.6 g of calcium of oxide is formed. Calculate the mass of carbon dioxide formed. Which law of chemical combination will you use in solving this problem ?
The weight of oxygen that will react with 1 g of calcium is
The atomic mass of calcium (Ca) is 40 g. The number of moles in 60 g of calcium are
