For the balanced equation shown below, how many moles of Al will react with 98.7 moles of CuSO4

65.8 mol

Explanation:

Step 1: Write the balanced equation for the single displacement reaction

2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + 3 Cu

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of Al to CuSO₄ is 2:3.

Step 3: Calculate the number of moles of Al that will react with 98.7 moles of CuSO₄

98.7 mol CuSO₄ × 2 mol Al/3 mol CuSO₄ = 65.8 mol Al

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
