Question

Цепочка по химии !Ca-Ca(OH)2-Caso4-H2So4Na-Na2o-NaOH-Cu(OH)2-Cuo

Answer 1

1) Са+Сu(ОН)2= заканчивать не буду
2)Сa(OH)2+Na2SO4=
3)CaSO4+HCl
1) Na+H2O=Na2O2-  это промежуточная Na2O2+2Na=2Na2O
2)Na2O+ H2O=
3)NaOH+CuCl2=
4) Cu(OH)= разлагается при температуре  CuO+H2O

Answer 2

Ca + 2H2O ---> Ca(OH)2 + H2
Ca(OH)2 + H2SO4 ---> CaSO4 + 2H2O
3CaSO4 + 2H3PO4 --> Ca3(PO4)2 + 3H2SO4

2Na + O2 ---> Na2O
Na2O + H2O --> 2NaOH
2NaOH + CuCl2 ---> 2NaCl + Cu(OH)2
Cu(OH)2 --t--> CuO + H2O

Answer 3
