If aqueous solutions of Na2CO3 and BaCl2 are mixed, which insoluble precipitate is formed?

barium chloride (BaCl2) is added to sodium carbonate (Na2CO3). The result is a white precipitate.

Explanation:

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
