Solution Summary: The author explains that precipitation reaction occurs between cation and anions in aqueous solution combines to form an ionic solid mass called precipitate.
For the following chemical reactions, determine the precipitate produced when the two reactants listed below are mixed together. Indicate “none” if no precipitate will form.

Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.
we were assigned to dilute 900ppm
in to 18ppm by using only 250ml vol
flask. firstly we did calc and convert
900ppm to 0.9 ppm to dilute in 1 liter.
to begin the experiment we took
0,225g of kmno4 and dissolved in to
250 vol flask. then further we took 10
ml sample sol and dissolved in to 100
ml vol flask and put it in to a
spectrometer and got value of 0.145A
.
upon further calc we got v2 as 50ml
. need to find DF, % error (expval and
accptVal), molarity, molality. please
write the whole report. thank you

Q5. Predict the organic product(s) for the following transformations. If no reaction will take place
(or the reaction is not synthetically useful), write "N.R.". Determine what type of transition state
is present for each reaction (think Hammond Postulate).
