Question

the weight of oxygen that will react with 1g of calcium is
​

Answer 1

1g of oxygen will react with 1 g of calcium and form calcium oxide.

2Ca+O 2 = 2CaO.

HOPE THIS HELPS U!!!!!!!!

Answer 2

Answer:

The reaction is

2Ca + O2 = 2Ca

moles of Ca in 1 g = 1/40

now moles of O2 needed for 1/40 moles of Ca

= 1/2*(1/40) = 1/80

So, mass of O2 will be = 32 * (1/80) = 2/5 = 0.4g
