Question
11. Is this compound an acid or a base: H20?
Answer: IT IS A BASE
A substance that accepts and H+ from water is considered a base. Both NH3 and H2O are amphoteric (they have H atoms that can be donated as H+ ions and thus act as acids and lone-pair electrons that can accept an H+ and thus act as bases). Thus, either NH3 or H2O can act as an acid or a base.
PLZ GIVE BRAINLIEST +THANKS :)
Answer:
Neutral
Explanation:
It has a pH of 7, so it is considered neutral, and neither an acid nor a base. This means it is a neutral!

Answer:
yessss what's ur snapp?
NaClO, K2CO3, and NaF will form basic soltions.
Solution is here,
for initial case,
temperature(T1)=70°C=70+ 273=343K
vloume( V1) =45 L
for final case,
temperature( T2)=?
volume(V2)= 91.3 L
at constant pressure,
V1/V2 = T1/T2
or, 45/91.3 = 343/ T2
or, T2= (343×91.3)/45
or, T2=695.9 K = (695.9-273)°C=422.9°C
