## Word Equation

The chemical reaction between aluminium sulphide and water produces hydrogen sulphide and aluminium hydroxide.

## Input Interpretation

The balanced chemical equation for the reaction is as follows:

Al2S3 + H2O → H2S + Al(OH)3

Aluminium sulphide and water react to form hydrogen sulphide and aluminium hydroxide.

## Balanced Equation

To balance the chemical equation, we need to add stoichiometric coefficients to both the reactants and products. The coefficients represent the relative number of molecules or atoms of each element involved in the reaction.

Al2S3 + H2O → H2S + Al(OH)3

Next, we need to set the number of atoms of each element in the reactants equal to the number of atoms in the products.

C1Al2S3 + C2H2O → C3H2S + C4Al(OH)3

This gives us a system of equations that we can solve algebraically.

Al: 2C1 = C4

S: 3C1 = C3

H: 2C2 = 2C3 + 3C4

O: C2 = 3C4

Since there are more variables than equations, we can arbitrarily set one of the coefficients to 1. For simplicity, let's set C1 to 1 and solve for the remaining coefficients.

C1 = 1

C2 = 6

C3 = 3

C4 = 2

Substituting these coefficients into the balanced equation, we get:

1Al2S3 + 6H2O → 3H2S + 2Al(OH)3

This is the balanced chemical equation for the reaction between aluminium sulphide and water, which produces hydrogen sulphide and aluminium hydroxide.
