Answer:-
H2SO3 (aq)
Explanation:-
NaCl, KOH and HCl ionic compounds.
Ionic compounds dissociate into ions in water.
Ions can carry electricity in water. So NaCl, KOH and HCl are all strong electrolytes.
H2SO3 is not a strong acid and dissociates to a small extent into ions in water.
Hence number of ions formed is less. Hence it is a weak electrolyte.
Answer:
The answer you have selected is correct
Explanation:
delta g must be negative in order for the reaction to be spontaneous bb ♡
Explanation:
The total mass is:
100 g + 200 g
= 300 g
The mass of salt is:
0.20 (100 g) + 0.10 (200 g)
= 20 g + 20 g
= 40 g
So the concentration is:
40 g / 300 g
≈ 13.33%
Round as needed.
