The calcium ion is Ca2+ and the hydride ion is H-. So, the subscript for the Ca is 1 and the subscript for H is 2. The formula unit is CaH2. The subscript 1 for Ca is not written. When there is no subscript it is understood to be 1.

How many grams of calcium hydride are needed to form 4.850 g of hydrogen gas?

To calculate the amount of calcium hydride needed to form 4.850 g of hydrogen gas, you need to use the molar ratio between calcium hydride (CaH2) and hydrogen gas (H2), which is 1:2. Therefore, you would need half as many grams of calcium hydride as the grams of hydrogen gas produced, so 2.425 g of calcium hydride would be needed.
