I was doing a question that asks the molarity of a 10 mL of tartaric acid that is titrated to phenolphthalein endpoint with 20 mL of 1.0 M NaOH. I worked it out by equating the molarity of the NaOH times its volume to that one of the tartaric acid and got a value of 2.0 M but as tartaric acid is...

(3R, 4S)-3-ethyl-3,4-dimethyl-1-hexene Draw the Fischer Projection of the compound above. Here is the answer: Is there a mistake at the upper stereocenter? I think so.

So I have a few dumb questions. I'm still in high school and am doing something on magnetic properties of transition metals. I'm facing a few roadblocks. 1) What're compounds like $\ce{CoBr2, CoCl2, AgI, AgBr, AgCl, AgF, MnBr, Co(CN)2}$, supposed to be? Are they the same as the coordinate comple...

We have a investigation in my chemistry class in which we must calculate the amount of calcium carbonate in sea shells. We can have as many sea shells as we wish, lab equipment, and hydrochloric acid of varying concentration from $0.5~\mathrm{mol~dm^{-3}}$ to $2~\mathrm{mol~dm^{-3}}$. How is it t...
