I need some advice, so i talk to this one guy and there’s sort of like a problem. When i talk to someone i want like a minute to like reply back or sum... so this guy i well like A LOT and i think he feels the same way but when we talk there’s like a week when he reply’s back. SO like he say’s hey they i reply back in like 4 minutes and say hey then like 2 weeks later he says wyd. I really need to know what to do with him bc we’ve been doing this for like 6 months and there’s no difference what do i do with him???

that's what i got you can count the number of atoms

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
