Which one of the following salts has the highest molar solubility in water?
1 answer:
Answer:
Correct option is
C
Ag
2
CO
3
; K
sp
=6.2×10
−12
(A) For CaCO
3
,S=
Ksp
=
8.7×10
−9
=9.3×10
−5
M
(B) For CuS,S=
Ksp
=
8.5×10
−45
=9.2×10
−23
M
(C) For Ag
2
CO
3
,S=(Ksp/4)
1/3
=(6.2×10
−12
/4)
1/3
=1.15×10
−4
M
(D) For Pb(IO
3
)
2
,S=(Ksp/4)
1/3
=(2.6×10
−13
/4)
1/3
=4×10
−5
M
Hence, Ag
2
CO
3
has the greatest molar solubility in pure water.

so one liter is about 2. something gallons so at 12.8 km/l you would get about 30 mpg which is insane but yeah
The molarity remais the same
Answer:
the answer is C
Explanation:
it can form 3 bonds
D.) Balanced equation is Zn + 2HBr - - - > ZnBr2 + H2.
