Calculate the molarity of 0.300 mol of Na2S in 1.75 L of solution.
Jobisdone [24]
First equation:
molarity=
no.of moles of solute (Na2S)/volume of solution
0.300/1.75 = 0.171
second equation:
same law
but in volume it is milliliter so you have to convert it by multiplying it with 10^-3
(10 power -3)

Nh4cl is sometimes preferred instead of hcl or h2so4 for "acid" work-up after grignard reactions, particularly when the expected
Free_Kalibri [48]

Nh4cl is sometimes preferred instead of hcl or h2so4 for "acid" work-up after grignard reactions, particularly when the expected and desired product is a tertiary alcohol because NH4+ is a much milder acid than HCl or H2SO4, which achieve the protonation of

the oxyanion to yield the alcohol while minimizing the risk of dehydration.

Ammonium chloride (NH4Cl) is the used as reagent that quenches the magnesium alkoxide product of the Grignard addition.

It is a proton source without being acidic as in acidic medium the protonation of the tertiary alcohol product and elimination to the alkene.

In the presence of HCl or any other strong acid protonation proceed and form alkene but not with ammonium chloride.

Thus from above we concluded that Nh4cl is preferred instead of hcl or h2so4 for "acid" work-up after grignard reactions.

Why are some rocks more easily weathered than other rocks
dmitriy555 [2]
Because of their atom's composition. some are naturally packed closer together and stronger and more durable, while others tend to be more loose and breakable and/or weaker/less durable. also with how their atoms are composed is how the atoms interact with each other/ how they share or give or take electrons.
