Let the hydrated compound be CaSO4.xH2O
mass of the caso4= 43.63g /(40+32+64+18x)* (40+32+64)= 36.45g
136+18x=( 43.63*136) / 36.45= 162.78
18x = 162.78- 136= 26.8
x = 1.48 = 1.5
Formula of hydrate = CaSO4.1.5H2O = 2CaSo4. 3H2O

Thus A is the correct answer.

The formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1. as shown below:

  • N_2 + 3H_2 \rightarrow 2NH_3
<h3>What is the equation of the formation of ammonia?</h3>

Ammonia gas is formed from the reaction between nitrogen gas and hydrogen gas.

Three moles of hydrogen gas will react with 1 mole of nitrogen gas to form 2 moles of ammonia gas.

The equation of the reaction is given below as:

N_2 + 3H_2 \rightarrow 2NH_3

Therefore, the formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1.
