Question

1. choose the best answer using the periodic table. which of the following compounds would have the strongest bond? a compound with triple bonds a compound with double bonds a compound with single bonds 11. choose the best answer using the periodic table. what is the name of this compounds name: mg₃p₂? magnesium phosphorus phosphorus magnesium magnesium phosphide trimagnesium diphosphide 12. choose the best answer using the periodic table. what is the correct chemical formula for a compound made from li and o? li₃o li₂o li₃o₂ lio

Explanation:

Step1: Analyze bond strength trend

Bond strength increases with bond order: triple bonds > double bonds > single bonds, as more shared electron pairs create stronger attraction between atoms.

Step2: Identify correct ionic compound name

For $\text{Mg}_3\text{P}_2$: Mg has +2 charge, P has -3 charge. Use crisscross rule to confirm formula, then name as cation + anion (phosphide) with prefixes for subscripts when needed; here, it's magnesium phosphide.

Step3: Derive Li-O compound formula

Li has +1 charge, O has -2 charge. Crisscross charges to get subscripts: $\text{Li}_2\text{O}$.

Answer:

1. a compound with triple bonds
2. magnesium phosphide
3. $\text{Li}_2\text{O}$
