Select the correct answer How is the salt formed in a neutralization reaction written in a chemical reaction?
A. The cation is from the base and the anion is from the acid.
B.
The cation is from the acid and the anion is from the base.
C. The cation and anion both come from the dissociation of water.
D.
The cation and anion may come from either acid or base, depending on their equilibrium constants.

have a great day because if you dont you and i will be sad

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2

you gotta add the following molecules so we can give u an answer
