ch. 14 & 7 IMF & chemical equations ; 40 points [2 ec]

1. identify the types of IMF in the following compounds; justify your response by including a sketch of the appropriate shape of the molecule and determining if it's a polar or nonpolar compound with its rationale. [10 points]

a. sulfur tetrafluoride

b. carbon tetrafluoride

2. Which compound, water or carbon dioxide, has larger boiling point ? Justify / rationalize your answer based on the type of IMF in the compound. [10 points]

3. Write the chemic equation, including information about the physical state of hte chemicals. Do not "balance" the chemical equations with the appropriate coefficients, but you'll have to use the appropirate chemical formula. [11 points]

a. mixing aqueous solutions of calcium nitratre and potassiu m carbonate forms an aqueous solution of potassium nitrate and a precipitate of calcium carbonate

b. the addition of solid sodium into liquid water forms hydrogen gas adn an aqueous solution of sodium hydroxide

c. an aqueous solution of hydrogen peroxide decomposes into liquid water and oxygen gas

4. fill-in the belo blanks to "balance" the chemical equations using the lowest ratio of integers; enter "1" as appropriate. [11 points]

a. __ H2 + __ Cl2 → __ HCl

b. __ C3H7OH + __ O2 → __ CO2 + ___ H2O

c. __ magnesium nitrate + __ litium phosphate → ___ magnesium phosphate + __ lithium nitrate
