How many moles of A1 are needed to react with each mole of CuSO4 in the reaction 2AI + 3CuSO4 -> 3Cu + AI2(SO4)3.

1 mole CuSO4 x (2 moles Al/3 moles CuSO4) = 1 x (2/3) = ? moles Al.

To determine the number of moles of A1 needed to react with each mole of CuSO4, we need to look at the balanced chemical equation and the stoichiometry of the reaction.

The balanced equation is:
2AI + 3CuSO4 → 3Cu + AI2(SO4)3

From the equation, we can see that 2 moles of A1 react with 3 moles of CuSO4.

Therefore, to find the ratio of moles between A1 and CuSO4, we can set up a proportion using this relation:

2 moles A1 / 3 moles CuSO4 = x moles A1 / 1 mole CuSO4

Simplifying the proportion, we have:
2/3 = x/1

Cross-multiplying, we find that:
2 × 1 = 3 × x

This simplifies to:
2 = 3x

To solve for x (the number of moles of A1 needed to react with each mole of CuSO4), we divide both sides of the equation by 3:

2/3 = x

Therefore, each mole of CuSO4 reacts with 2/3 moles of A1.

In summary, 2/3 moles of A1 are needed to react with each mole of CuSO4 in the given reaction.
