The double-replacement reaction of sulfuric acid with aluminum hydroxide produces aluminum sulfate salt and water. balance this skeleton equation, then determine the mole ratio of h2so4: h2o. h2so4 + al(oh)3 al2(so4)3 + h2o? (how do i determine the mole ration? )
a) 1: 1
b) 2: 3
c) 3: 1
d) 3: 6
e) 6: 3

D) 3:6

Explanation:

This is a double displacement reaction in which exchange of ions take place.

According to the law of conservation of mass, mass is neither created nor destroyed. Thus the mass of products must be equal to the mass of reactants.The number of atoms of each element must be same on both sides of the reaction.Thus the equation is balanced.

The balanced chemical equation is:

The mole ratio of is 3:6.

i think   the answer is c hope i'm right
