Based on the electronegativity values, which molecule has a polar covalent bond? * Answers
A) Nitrogen molecule (N2)
B) Sodium fluoride
C) Sulfur teteraiodide
D) Dihydogen monoxide

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

Use this information to determine the number of calends electrons in the atoms. which of the following correctly compares the stability of the two atoms? a) both are unreactive b) both are highly reactive c) a is unreactive and d is reactive d) a is reactive and d is unreactive

Answer explain why it is not possible to deduce a complete order of reactivity.
