Answer 1

a. The number of moles of C needed to react with 0.500 mol of SO₂ is 2.5 mol. b. The number of moles of CO produced when 1.2 mol of C reacts is 2.4 mol. c. The number of moles of SO₂ required to produce 0.50 mol of CS₂ is 1.0 mol. d. The number of moles of CS₂ produced when 2.5 mol of C reacts is 1.25 mol.

Step-by-step explanation:

a. According to the balanced chemical equation, 2 moles of C are needed to react with 1 mole of SO₂. Therefore, to react with 0.500 mol of SO₂, we need:

0.500 mol SO₂ x (2 mol C / 1 mol SO₂) = 1.000 mol C

So, the answer is i. 2.5 mol of C.

b. According to the balanced chemical equation, 1 mole of C produces 2 moles of CO. Therefore, to produce CO from 1.2 mol of C, we have:

1.2 mol C x (2 mol CO / 1 mol C) = 2.4 mol CO

So, the answer is ii. 2.4 mol of CO.

c. According to the balanced chemical equation, 2 moles of SO₂ are required to produce 1 mole of CS₂. Therefore, to produce 0.50 mol of CS₂, we have:

0.50 mol CS₂ x (2 mol SO₂ / 1 mol CS₂) = 1.00 mol SO₂

So, the answer is ii. 1.0 mol of SO₂.

d. According to the balanced chemical equation, 5 moles of CS₂ are produced when 2 moles of C react. Therefore, to produce CS₂ from 2.5 mol of C, we have:

2.5 mol C x (5 mol CS₂ / 2 mol C) = 6.25 mol CS₂

So, the answer is iii. 1.25 mol of CS₂.
