Answer:
R is universal gas constant
It is has fixed value which would depend upon the units in which P,V and T expressed in the equation PV=nRT
R=
nT
PV
It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
The vapour pressure of a substance actually differs
relative to the temperature. So to know which compound has the vapour pressure
of 58 kilopascals at 65 degrees Celsius, we refer to standard tables of
temperature vs Vapour pressure.
From the tables or graph, the answer here is:
