Question

Which of the following is not true of covalent bonds? they are never polar there is electron sharing they are between two nonmetals they are strong which of the following bonds is the most polar? N..O Os NaO FCl in ionic equations which of the following are written as ions soluble ionic compounds insoluble ionic compounds strong acids strong acids weak acids covalent compounds in a solution there is more solute than solvent more solvent than solute equal amounts of solute and solvent the relationship between solute and solvent cannot be determined. A20% salt solution by mass has 20g of salt in 100g of water 20g of salt in 100g of solution 20g of salt in 80g of solution cannot be determined from the information here

Explanation / Answer

6. a they are never polar. if they have electronegativity diference, they are partially polar.

7. c Na-O , Na is metal electropositive , others are non-metals electronegative

8. a, c, d

9. b more solvent than solute to make a solution

10. c 20 g salt in 100 g solution
