(A) 0.2
(B) 0.5
(C) 0.4
(D) 0.1
Heyy! Please help me in this question ​

Answer 1

Answer:

0.2

Explanation:

limiting reagent reaction:

H2SO4 + Ca(OH)2----> CaSO4 + H2O

For 1 mole of sulphuric acid 1 mole of Ca(OH)2 is required

=> for 0.5 mole of h2so4 0.5 mole Ca(OH)2 is required... but only 0.2 mole is given

=> Ca(OH)2 is the limiting reagent

Fron reaction..

1 mole of Ca(OH)2 gives 1 mole of CaSO4

=> 0.2 mole of Ca(OH)2 gives 0.2 moles of CaSO4
