Ineed getting an idea for my science fair idea but my teacher said it had to be something useful and that you can research on. no silly experiments that last a day, !

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?

For each of the following compounds, write the formula then predict whether it would be a strong, weak, or non-electrolyte when placed in di water. for the ionic compounds only, put (s) or (aq) after the forrmula formula strong, weak or non electrolyte? a calcium hydroxide b. silver carbonate c. lead(ii) sulfate d. phosphorus trifluoride e. sodium phosphide f barium sulfate g. strontium acetate h. zinc nitrate

Why is carbon ideal for making different compounds?
