Question

barium nitrate has the formula ba(no₃)₂. which statement is true about barium nitrate? each molecule contains four different elements. each molecule contains three atoms. each molecule contains seven different bonds. each molecule contains six oxygen atoms.

Explanation:

In the formula Ba(NO₃)₂, the sub - script 2 outside the parentheses means that all the atoms within the parentheses are multiplied by 2. There is 1 barium (Ba) atom, 2 nitrogen (N) atoms, and 2×3 = 6 oxygen (O) atoms. There are 3 different elements (Ba, N, O). The number of atoms is 1 + 2+6 = 9. Information about the number of bonds is not provided by just the formula in a simple way as stated in the option about bonds.

Answer:

Each molecule contains six oxygen atoms.
