)What is the correct formula for the ionic compound that forms when oppositely- charged ions of calcium and carbonate attract? (ANSWERS ARE IN THE IMAGE)

CaCO₃

Explanation:

Calcium ion is written as Ca²⁺

Carbonate ion is written as CO₃²¯

During bonding, the +2 ions from the calcium and the –2 ions from the carbonate will cancel out given a net charge of zero as shown below:

Ca²⁺ + CO₃²¯ —> CaCO₃

Thus, the correct formula for the ionic compound that forms when oppositely charged ions of calcium and carbonate attract is CaCO₃.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
