Final answer:
The type of salt obtained from Magnesium chloride and Calcium carbonate, and the respective acid and base sources for these salts.
Step-by-step explanation:
The salt obtained from Magnesium chloride and Calcium carbonate is Magnesium chloride.
Magnesium chloride yields an acidic salt, and the acid source for this salt is hydrochloric acid.
Calcium carbonate, on the other hand, yields a basic salt, and the base source for this salt is calcium hydroxide.
