H3c6h507(aq) + 3nahco3(aq) - na3c6h5o7(aq) + 3c02(g) + 3__
which product formula correctly completes the equation?

2 h₂o
3 naoh
4 cooh

a) the particles of the chair are strongly held together.

answer: i dont know the answer but this might

explanation:

l

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
