Answer: Hydrogen gas will be given off

Explanation:

Whenever a metal reacts with an acid, a salt of the metal is formed and hydrogen gas is given off.

For instance: The reaction of Zinc metal on Hydrochloric acid.

Zn(s) + 2HCl(aq) ---> ZnCl2(aq) + H2(g)

From the equation provided, hydrogen gas is given off as a by-product

If 3.3167 moles of Al are produced, how many moles of<br> AlCl3 were reacted?<br> I
tresset_1 [31]

Answer:

3.3167 moles Of AlCl3

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

3Ca + 2AlCl3 —> 3CaCl2 + 2Al

From the balanced equation above,

2 moles of AlCl3 reacted to produce 2 moles of Al.

Finally, we shall obtained the number of moles of AlCl3 that reacted to produce 3.3167 moles of Al as follow:

From the balanced equation above,

2 moles of AlCl3 reacted to produce 2 moles of Al.

Therefore, 3.3167 moles Of AlCl3 will also react to produce 3.3167 moles of Al.

Thus, 3.3167 moles Of AlCl3 is needed for the reaction.
