Question

Aluminium reacts with hcl to produce h2 according to equation

Answer 1

Answer:

6HCl(aq) + 2Al(s) ---------> 2AlCl$_{3}$(aq) + 3H$_{2}$(g)

Explanation:

HCl + Al ---------> AlCl$_{3}$ + H$_{2}$

The above equation is an incomplete one as it is a skeleton chemical equation.

A skeleton chemical equation is one that is not balanced. If an equation is not balanced, it means that the number of atoms of each element on either side of the arrow is not equal.

Hence, below is the balanced form of the above equation,

6HCl + 2Al ---------> 2AlCl$_{3}$ + 3H$_{2}$

Let's also mention the state of the compounds beside their names in the reaction itself,

6HCl(aq) + 2Al(s) ---------> 2AlCl$_{3}$(aq) + 3H$_{2}$(g)

Answer 2

Answer:

Explanation:

2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g) What Mass Of H2(g) Is Required From The Reaction Of 0.75 G Of Al(s) With Excess Hydrochloric Acid? ... The Reaction Of Coal And Water At A High Temperature Produces A Mixture Of Hydrogen And Carbon Monoxide Gases.
