Question

Which of the following products would be possible in the reaction of 2 moles of aluminum (Al) with 6 moles of hydrochloric acid (HCl)? A. 2 moles of AlCl2 and 1 mole of H2 B. 3 moles of AlCl3 and 2 moles of H2 C. 2 moles of AlCl3 and 3 moles of H2 D. 3 moles of AlCl2 and 3 moles of H2

Answer 1

Balanced equation:

`2 \ Al + 6 \ HCl \to 2 \ AlCl_3 + 3 \ H_2`
2 moles of Al react with 6 moles of HCl. 2 moles of AlCl₃ and 3 moles of H₂ are produced.

The answer is C.
