Question

Consider the reaction
Al(OH)3 + 3HCI → 3H2O + AICI3
If 14.0 grams of aluminum hydroxide are
allowed to react with hydrochloric acid,
how much aluminum chloride is
produced?
a) 14.0g b)17.9 g c) 23.9 g d) 30 g
​

Answer 1

Answer:

the answer is

... c). 23.9

Answer 2

Answer:

c) 23.9 g

Explanation:

Al(OH)3 + 3HCl    →    3H2O + AlCl3

78g        3×36.5g      3×18g     133.5g

78g of Al(OH)3 react with HCl to produce 133.5g of AlCl3

Similarly

14g of Al(OH)3 react with HCl to produce (133.5/78) × 14 = 23.9 g of AlCl3
