Answer:
ok all you need is a little study
Explanation:
organic chemistry isn't something to worry about is something that is a very simple concept if you understand what you're doing so a little bit of studying will help you go through it and you really don't this is not the topics that you will really understand if you just go through it as once so there is no need to worry about organic chemistry it is very simple concept just learning you are a you are close just learn all those simple aspects alkane etc it's very easy
The awnser to your question would be B
Reaction equation:
Zn + 2HCl → ZnCl₂ + H₂
One mole of gas occupies 22.4 L at STP
Moles of H₂ = 112/22.4
= 5 moles
The theoretical amount of Zn needed is 5 mol
The actual amount = 5/0.85
= 5.88 moles
mass = moles x Mr
mass = 5.88 x 65
mass = 382.2 g
The answer is D.
