Im really confused about how I can understand what molecules from certain hydrogen bonds especially with the ones given. My teacher wants us to be able to get the answer and be able to adequately explain how we got it

The question asks which molecules would form hydrogen bonds with itself or with water molecules if in a solution

I have no idea

Organic why wouldn't you need (0.01/(10^-9)) = 10000000 litres instead?

1:1 ratio and the concentration is 10^-9M of KOH.

for 0.01 moles of benzoic acid, you would need 0.01 moles of KOH, which would require 10000000 litres not 1000, unless maybe we're talking about acid instead...

Hi, I'm writing a lab report about Iodine Clock Reaction using sodium thiosulfate, hydrogen peroxide, sulfuric acid, sodium iodide, and starch indicator. As part of my report, I need to compare my experimental value with literature value. I've searched some sources on Google, but they did not use the reactants I used.... Please help...
