<span>This type of reaction is called a synthesis reaction. This type of reaction occurs when two or more components combine to form a single compound. During this formation, heat and energy is released, ergo it is an exothermic type of reaction.</span>

Answer:
158.5g Zn are produced
Explanation:
To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:
<em>Moles Al -Molar mass: 26.98g/mol</em>
43.6g Al* (1mol/26.98g) = 1.616 moles Al
<em>Moles Zn:</em>
1.616 moles Al * (3mol Zn / 2mol Al) =
2.424 moles Zn are produced
<em>Mass Zn -Molar mass: 65.38g/mol-</em>
2.424 moles Zn * (65.38g / mol) =
<h3>158.5g Zn are produced</h3>
isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
