If you don't mind having 97%ethanol, methylated spirits(the 3% is why its called methylated). That would be the only normal way of getting some, do you mind if I ask why.
Ammonium Hydroxide? That is just ammonia in water. Get a NH4+ and OH- and obviously the H+ will be attracted to the OH- and you'll get water. If you have some other source of OH-(NaOH) then the vast majority of the ammonia will be NH3. Apart from that, yeh:
NH3+HCl -->NH4Cl
To melt is the latent heat of fusion. Silly name but hey.
To boil is latent heat of vapourisation
The important bit is the state symbols because nothing else is happening. All others in solution(aq).
Ag+ + NO3- + Na+ + Cl- --->AgCl(s) + NO3- + Na+
AgCl is a white precipitate which dissolves in dilute ammonia solution so is a good test for Cl- ions. The same happens with Br- - to give … Read more
P2O5+ 3H20 --->2 H3PO4
Nice, get someone else to do your exam!
Propane(van der waals/temporary dipole)
Methoxymethane(dipole-dipole)
Ethanol(hydrogen bonds)
Basically it because of the structure.
H3PO4 is
O-H
/
O=P-O-H
\
O-H
so each H+ can be removed to leave -Ominus.
H3PO3 is
O-H
/
O=P-H
\
O-H
Pminus is just too unstable compared with Ominus. Oxygen is more electronegative, but I reacon its more complex than … Read more
