What is the balance for the equation Al + HCl= AlCl3 + H2?

[ISneezeFunny]

to balance equations, separate each element

Al
H
Cl

then assign a letter (A, B, C, D) for each compound found in the equation above, and make an equation.

for Al: 1A = 1C
for H: 1B = 2D
for Cl: 1B = 3C

assume A = 1, and solve

A = 1
C = 1
B = 3
D = 3/2

now make them all whole

A = 2
C = 2
B = 6
D = 3

2Al + 6HCl = 2AlCl3 + 3H2
