-> Acidic

-> Basic

-> Neutral

Explanation:

Hello,

In this case, considering the given salts, , , one classifies them as follows:

- : ammonium chloride is an acidic salt since it comes from ammonium hydroxide which is a weak base and hydrochloric acid which a strong base, thus, due to the partial neutralization, there are still traces of an acidic character which provides such behavior for this salt.

- : sodium hypochlorite is a basic salt since it comes from sodium hydroxide which is a strong base and hypochlorous acid which is a weak acid by means of the contrary behavior of the since traces of a basic character promote such basic behavior.

- : potassium nitrate is a neutral salt as long as it comes from the potassium hydroxide which is a strong base and the nitric acid which is a strong acid, promoting the complete neutralization.

Best regards.

i think that is the right

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
