Question

Zinc+hydrochloric acid= complete and balance. Show work.no need to explain just show what’s steps are being done.

Answer 1

`2Zn+2\text{HCl}\rightarrow2\text{ZnCl}+H_2`

Explanations:

According to the question, we are balancing the equation between the zinc element and hydrochloric acid as shown:

`aZn+b\text{HCl}\rightarrow cZnCl+dH_2`

Next is to balance the chemical reaction by determining the coefficient

For the zinc element:

a = c

For the hydrogen element:

b = 2d

For the Chlorine element

b = c

Recall that d = b/2 = c/2

Substitute the coefficient into the reaction in terms of "c"

`\begin{gathered} aZn+b\text{HCl}\rightarrow cZnCl+dH_2 \\ \text{cZn}+\text{cHCl}\rightarrow\text{cZnCl}+(c)/(2)H_2 \\ \text{Cancel out the constant '}c\text{'} \\ Zn+\text{HCl}\rightarrow\text{ZnCl}+(1)/(2)H_2 \\ \text{Multiply through by 2} \\ 2Zn+2\text{HCl}\rightarrow2\text{ZnCl}+H_2 \end{gathered}`

This gives a balanced chemical reaction for the reaction
