When the following equation is balanced with the lowest whole number coefficients possible, what is the coefficient in front of AlCl3?


Al (s) + ZnCl2 (aq) ----> Zn (s) + AlCl3 (aq)

  • 1
  • 2
  • 3
  • 6

Verified Answer :

coefficient is 2
2Al (s) + 3 ZnCl2s (aq) --> 3 Zn (s) + 2 AlCl3 (aq) 

Answer: The coefficient in front of \(AlCl_3\) is '2'.

Explanation:

Coefficient is defined as number coming before the formula unit of molecule of a compound in chemical reaction.

\(2Al(s)+3ZnCl2(aq)\rightarrow 3Zn(s)+2AlCl3(aq)\)

From the balance chemical equation, 2 moles of aluminum are reacting with 3 moles of zinc chloride to give 3 moles of zinc metal and 2 moles of aluminium chloride as a product.

Here, the coefficient of the aluminum chloride is '2'.
