Question

question 9 (1 point)
write the name of each chemical formula
bin

question 10 (1 point)
write the name of each chemical formula
sno₂

Explanation:

For \(BiN\), bismuth (\(Bi\)) is a metal and nitrogen (\(N\)) is a non - metal. Using the naming rules for ionic compounds (metal + non - metal), we name it bismuth nitride.
For \(SnO_{2}\), tin (\(Sn\)) is a metal with variable oxidation states. Oxygen (\(O\)) has an oxidation state of \(- 2\). In \(SnO_{2}\), using the formula \(x + 2\times(-2)=0\) (where \(x\) is the oxidation state of \(Sn\)), we find \(x = + 4\). So, following the naming rules for ionic compounds with metals having variable oxidation states (using Roman numerals), we name it tin(IV) oxide.

Answer:

bismuth nitride
tin(IV) oxide
