Calculate the number of moles of H2SO4 required to react with 66.33 moles of Al. Do not include units in your answer. Round to the tenths place or further.

99.5 moles

Explanation:

The reaction equation is;

2Al(s) + 3H2SO4(aq) > Al2(SO4)3(aq) + 3H2(g)

From the balanced reaction equation;

2 moles of aluminium reacts with 3 moles of acid

Therefore 66.3 moles of Al reacts with x moles of acid

66.3 * 3 = 2x

x = 99.45 moles

x = 99.5 moles

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

it's filtration, but this is an assumption so my apologies if i got this
