Химические уровнения 1. Al+H2SO4 = ? 2. NaOH + H2SO4 = ? 3. Ba(OH)2 + HPO3 = ?

Question

Химические уровнения
1. Al+H2SO4 = ?
2. NaOH + H2SO4 = ?
3. Ba(OH)2 + HPO3 = ?

Answer 1

2Al+3H2SO4=Al2 (SO4)3+ 3H2(стрелка вверх)
2NAOH+H2SO4=NA2SO4+2H2O
Ba (OH)2+2HPO3=Ba (PO3)2+2H2O

Answer 2

2Al+3H2SO4=Al2(SO4)3+3H2
2NaOH+H2SO4=Na2SO4+2H2O
