Answer:
A) 1.5 moles  B) 1.5 moles  C) 3.5 moles  D) 2/3 moles
Explanation:
A) 1 mole of COâ‚‚ gives 1 mole of CHâ‚„ and 2 moles of Hâ‚‚O, i.e, 3 moles of products. So 0.5 moles of COâ‚‚ gives 3 x 0.5 = 1.5 moles of products.
B) 1 mole of BaCl₂ gives 2 moles of AgCl and 1 mole of Ba(NO₃)₂, i.e, 3 moles of products. So 0.5 moles of BaCl₂ gives 3 x 0.5 = 1.5 moles of products.
C) 1 mole of C₃H₈ gives 4 moles of H₂O and 3 moles of CO₂, i.e, 7 moles of products. So 0.5 moles of C₃H₈ gives 7 x 0.5 = 3.5 moles of products.
D) 3 moles of H₂SO₄ gives 1 mole of Fe₂(SO₄)₃ and 3 moles of H₂, i.e, 4 moles of products. So 0.5 moles of H₂SO₄ gives 4/3 x 0.5 = 2/3 moles of products.
The moles of product will be:
A) 1.5 moles
B) 1.5 moles
C) 3.5 moles
D) 2/3 moles
Balanced chemical equation:
It occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. The number of moles of product for each reaction will be:
Let's solve each given reaction one by one for moles of product:
A) CO₂(g) + 4H₂(g) → CH₄ (g) + 2H₂O(l)
1 mole of COâ‚‚ produces 1 mole of CHâ‚„ and 2 moles of Hâ‚‚O.
Thus, 3 moles of products. So, 0.5 moles of COâ‚‚ gives 3 * 0.5 = 1.5 moles of products.
B) BaCl₂ (aq) + 2AgNO₃ (aq) → 2AgCl (s) + Ba(NO₃)₂ (aq)
1 mole of BaCl₂ gives 2 moles of AgCl and 1 mole of Ba(NO₃)₂.
Thus, 3 moles of products. So, 0.5 moles of BaClâ‚‚ gives 3 * 0.5 = 1.5 moles of products.
C) C₃H₈ (g) + 5O₂ (g) → 4H₂O (l) + 3CO₂(g)
1 mole of C₃H₈ gives 4 moles of H₂O and 3 moles of CO₂.
Thus, 7 moles of products. So, 0.5 moles of C₃H₈ gives 7 * 0.5 = 3.5 moles of products.
D) 3H₂SO₄ (aq) + 2Fe (s) → Fe₂(SO₄)₃ (aq) + 3H₂ (g)3 moles of H₂SO₄ gives 1 mole of Fe₂(SO₄)₃ and 3 moles of H₂.
Thus, 4 moles of products. So, 0.5 moles of Hâ‚‚SOâ‚„ gives 4/3 * 0.5 = 2/3 moles of products.
