Answer:
The answer to your question is: 1.28 x 10 ¹⁵ g of Fe₂(SO₄)₃
Explanation:
Single replacement reaction:
2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
M Fe = 55.8 g/mol
M H₂SO₄ = 98.1 g/mol
M Fe₂(SO₄)₃ = 399.9 g/mol
M H₂ = 2.0 g/mol
Fe₂(SO₄)₃ = 3.21 x 10¹² mol
Fe₂(SO₄)₃ = ? g
1 mol of Fe₂(SO₄)₃ ----------------- 399.9 g/mol of Fe₂(SO₄)₃
3.21 x 10¹² mol Fe₂(SO₄)₃ -------- x
x = (3.21 x 10¹² x 399.9 ) / 1
x = 1.28 x 10 ¹⁵ g of Fe₂(SO₄)₃
Carrying capacity, D
Emigration, C
Limiting factor, A
Population dynamics, B
The correct answer would be A. Energy is released.
