Question

Осуществите цепочку превращений:SrO → Sr(OH)2 → SrCl2 → Sr(NO3)2

Answer 1

Ответ:

1) SrO + H2O = Sr(OH)2

2) Sr(OH)2 + 2HCl = SrCl2 + 2H2O

3) SrCl2 + 2AgNO3 = Sr(NO3)2 + 2AgCl

Answer 2

SrO → Sr(OH)2 → SrCl2 → Sr(NO3)2

SrO (Strontium oxide) reacts with water (H2O) to form Sr(OH)2 (Strontium hydroxide): SrO + H2O → Sr(OH)2

Sr(OH)2 reacts with hydrochloric acid (HCl) to form SrCl2 (Strontium chloride): Sr(OH)2 + 2HCl → SrCl2 + 2H2O

SrCl2 reacts with nitric acid (HNO3) to form Sr(NO3)2 (Strontium nitrate): SrCl2 + 2HNO3 → Sr(NO3)2 + 2HCl
