Question

1. ZnCl2+Na3 Po4->Mgz3(Po4)2+NaCl 2. Ca(No3)2+K2Co3->CaCo3+KNo3 3. NaOH+H2So4->Na2So4+H2o Уровнить нужно

Answer 1

3ZnCl2 + 2Na3Po4 -> Zn3(Po4)2 + 6NaCl

 Ca(NО3)2 + K2CО3 -> CaCО3 + 2KNО3

2NaOH + H2SО4 -> Na2SО4 + 2H2О

Answer 2

1. 3ZnCl2 + 2Na3Po4 -> Zn3(Po4)2 + 3NaCl

2. Ca(NО3)2 + K2CО3 -> CaCО3 + 2KNО3

3. 2NaOH + H2SО4 -> Na2SО4 + 2H2О
