MgCO3 + 2LiCl is the product of the above reaction.
Hope this helps you.
Answer:
Neutral
Explanation:
They have the same # of protons and electrons
To write a complete balanced reaction of a redox reaction, we need to know the half reactions of the molecules involved in the reaction and to balance these reactions. From, the problem statement ClO2- is oxidized to ClO4- so the half reaction would be:
(ClO)2- = (ClO)4-
To balance,
We first balance the elements except O and H in the reaction.
(ClO2)- = (ClO4)-
Then, we balance O by adding H2O and balance H by adding H+
(ClO2)- + 2H2O = (ClO4)- + 2H+
Then, we balance the charges by adding electrons,
(ClO2)- + 2H2O = (ClO4)- + 2H+ + e-
Then for Ag+ to Ag,
Ag+ = Ag
We just need to balance the charge,
Ag+ + e- = Ag
To determine the final equation, we add both half reactions:
(ClO2)- + 2H2O = (ClO4)- + 2H+ + e-
Ag+ + e- = Ag

Answer:
The highest molar concentration is in the solution of potassium chloride because it's the one, with the highest molar mass.
Explanation:
If we have the same mass and the same volume in all the solutes and solutions, we should know the molar mass for each, to calculate how many moles of solute are we having.
a. LiOH → 23.94 g/m
b. KCl → 74.55 g/m
c. KOH → 56.1 g/m
d. NaOH → 40 g/m
The highest molar mass is in option b. It will have the most moles.
