Question

count the number of atoms of each of the following elements and record them on the table down below

Answer 1

Answer:

Explanation:

Here, we want to count the number of atoms of each element

Let us start with the reactant side

There are 2 hydrogen atoms (symbol H)

There are 2 chlorine atoms (symbol Cl)

There are 2 Zinc atoms (symbol Zn)

For the product side:

There are 2 Zinc atoms (dark circle)

There are 2 Chlorine atoms (Symbol Cl)

There are 2 hydrogen atoms (symbol H)

We have the equation of the model as:

$2\text{HCl + 2Zn }\rightarrow2ZnCl_{}_{}+H_2$
