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.
The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.
Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.
The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.
The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.
