The reaction includes the single replacement reaction and redox
<h3>Further explanation</h3>
Single replacement : one element replaces another element in a compound
A + BC ⇒ AC + B
The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number
3CuCl + 2Al => 3Cu + 2AlCl₃
Al replacing Cu in the CuCl compound
3Cu²⁺ + 6e⁻⇒ 3Cu reduction(oxidation number from +2 to 0)
2Al⇒2Al³⁺+6e⁻ oxidation(oxidation number from 0 to +3)
When water reaches its boiling point and turns into water vapor, the molecular structure of water remains the same. It is only the state of the substance that is changed in this process. I hope this helps you
26 because you need to do 54-28=26
The atomic mass number is the number of protons AND neutrons together.
