<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Galvanization is defined as the process in which a protective layer of zinc is applied to iron or steel to prevent the metal from rusting.
Zinc prevents the oxidation of iron and acts as a reducing agent in the process.
The half reaction for the process follows:
<u>Oxidation half reaction:</u> 
<u>Reduction half reaction:</u> 
Net chemical equation: 
Hence, the balanced chemical equation is written above.
Word equation - calcium + oxygen -> calcium oxide
Chemical equation - Ca + O2 -> CaO2

I think the answer would be medium
Answer:
The answer is
<h2>

</h2>
Explanation:
To find the number of atoms given the number of moles we use the formula
N = n × L
where
N is the number of entities
n is the number of moles
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question

Substitute the values into the above formula and solve
That's
<h3>

</h3>
We have the final answer as
<h3>

</h3>
