Question

if 56g of calcium oxide reacts with certain amount of water (X g) , a new compound with mass 74 g is formed . The value of (X g) is
1)130
2)92
3)18
4) 8

Give only the answer (explanation) , if something different given I will report against you​

Answer 1

Answer:

option (3)

Explanation:

mass is same in both sides in a chemical reaction means

mass of reactant= mass of products

calcium oxide (56g) + water (x) = new compound (74g)

56g+x=74g

x=74-56

x=18g

Answer 2
