Answer:
The answer to your question is 22.5 moles of H₂SO₄
Explanation:
Data
moles of H₂SO₄ = ?
moles of Al = 15
Balanced chemical reaction
2Al + 3H₂SO₄ ⇒ Al₂(SO₄)₃ + 3H₂
To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical reaction.
2 moles of Al ------------------- 3 moles of H₂SO₄
15 moles of Al ------------------ x
x = (15 x 3) / 2
x = 45/2
x = 22.5 moles of H₂SO₄
-Conclusion
22.5 moles of H₂SO₄ react completely with 15 moles of Al.
Answer:
the second one is the correct answer
Yes
It could have a non sufficient engine for the size of the plane so then I put couldn’t take off
Answer:
-the reactants have more energy stored because you didn't get a great amount ( if any ) of energy released after the reaction was complete.
-Mg + O2 = MgO + energy
Ideal Gas Law: PV=nRT
Divide both sides by P to isolate volume (V).
V=nRT/P
