Question

Balance the equation: Al + H2SO4 -----> Al2(SO4)3 + H2

Answer 1

When you are balancing the above equation, make sure to balance the oxygen atoms by identifying the required compound.

Since sulfate has 4 oxygen atoms and there are 3 moles, one may have to 4*3=12 to get the required atoms.


With 12 0 and 3 S on each side, one may have to increase the lone reactant Al by 2 2Al + 3H2SO4 = Al2 (SO4.3 + 3H2

Answer 2

$\huge\mathfrak{Question :}$

Balance the equation...

Al + H2SO4 ----> Al2(SO4)3 + H2


$\huge\mathfrak\red{Answer :}$

$2Al$ + $3H_{2}SO_{4}$ ----> $Al_{2}(SO_{4})_{3}$ + $3H_{2}$


In above equation...

Number of Al on both sides = 2

H = 6

S = 3

O = 12

Means the equation is balance...
