Answer:
11.4 moles of H₂SO₄ are needed to completely react the 7.6 moles of Al
Explanation:
The equation indicates that 2 moles of aluminum react to 3 moles of sulfuric acid in order to produce 1 mol of aluminum sulfate and 3 moles of hydrogen gas.
The reaction is: 2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
This question can be solved with an easy rule of three. Ratio in the reaciton is 2:3, so we propose:
2 moles of Al react with 3 moles of sulfuric acid
Then, 7.6 moles of Al will react with 11.4 moles of H₂SO₄
Answer:
Explanation:
Vaporization Equation => Q = m·ΔHv
m = 0.5Kg water = 500g water
ΔHv = Heat of vaporization = 540 calories/gram
∴Q = 500g x 540cal/g = 270,000 calories x 4.184 joules/cal = 1,129,680 joules = 1130 Kilojoules (3 sig. figs.)
Answer:
To convert 100.0 g of water at 20.0 °C to steam at 100.0 °C requires 259.5 kJ of energy. Let me know if this helped?
