Question

I REALLY NEED HELP PLEASE!!!!!!!!

1. 2Al + 3H2SO4 -> Al2(SO4)3 + 3H2 In the balanced equation above, what is the ratio of the reactant aluminum to the product aluminum sulfate?

2. What coefficients would be needed to balance the following chemical equation? Put them in order separated by commas. If no coefficient is needed, put a 1. example: 1,2,3,4 C2H4(g) + O2(g) ------> CO2(g) + H2O(g) A. 1,2,3,3 B. 2,1,1,2 C. 1,3,2,3 D. 1,3,2,2

Answer 1

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
