Answer:
4 L or 4000 mL
Explanation:
This question asks for the use of combined gas law:
(P1)(V1) / (T1) = (P2)(V2) / (T2)
...where pressure (P) is in atm, volume (V) is in liters, and temperature (T) is in kelvin.
1000 ml is 1 L, and everything else is already in the right units.
(1 atm)(1 L) / (20 K) = (0.5 atm)(V2) / (40 K)
Just solve the equation for V2, and you get a new volume of 4 liters
(1)(1) / (20) = (.5x) / (40)
1 / 20 = .5x / 40
2 = .5x
x = 4
In nitration u add two concentration acids HNO3 and H2SO4 both are strong acids. always the acid base neutralization reactions are fastest. even though NH2 group in aniline is a weak base, its neutralization with a very strong acid is still faster than nitration. hence if u carry the acid base reaction u would end up with an NH3+ group. hence the meta substitution can't be rule out here and u would get all products ortho,meta and para...
Answer:
the quantity of solution to moles for d is significantly lower.
Explanation:
the larger the amount of liquid, the less amount of ions to dissociate hence having a lesser amount of chloride ions.
compared to b which is less liquid and a higher concentration
Higher temp means lower vapor pressure
