Question

I just need some help getting the answers for this portfolio, but if someone could not only give the answers, but also explain how to get those answers so I better understand how to do this myself... It would be greatly appreciated.

Answer 1

The balanced chemical reaction has equal number of atoms in reactant side as well as product side.

Step-by-step explanation:

The balanced chemical reactions is as follows.

1.

`Zn+2HCl\rightarrow ZnCl_(2)+H_(2)`

2.

`4Fe+3O_(2)\rightarrow 2Fe_(2)O_(3)`

3.

`2H_(2)O_(2)\rightarrow 2H_(2)O +O_(2)`

4.

`NaHCO_(3)+HC_(2)H_(3)O_(2) \rightarrow NaC_(2)H_(3)O_(2)+H_(2)CO_(3)`

`H_(2)CO_(3)\rightarrow H_(2)O+CO_(2)`

`NaHCO_(3)+HC_(2)H_(3)O_(2)\rightarrow H_(2)O+CO_(2)+NaC_(2)H_(3)O_(2)`
