Answer: 1. The ratio of the reactant aluminum to the product aluminum sulphate is 2:1
2. Option D. 1,3,2,2
Explanation: 1. From the balanced equation:
2Al + 3H2SO4 -> Al2(SO4)3 + 3H2
2moles of Al produced 1mole of Al2(SO4)3. Therefore, the ratio will be 2:1
2. C2H4 + 3O2 ---> 2CO2 + 2H2O from the equation, the coefficients are 1,3,2,2
