Question

1) Give the total number of electrons avaliable for bonding in the molecule CH3COOCH3 ____

2)The functional group, COOH would be associated with an ___________?

a) ester

b) ketone

c) a carboxylic acid

d) all correct

3) A strong acid has a pH that is _______

a) higher than a weak acid

b) lower than a weak acid

c) higher than a weak base

d) two of the choices are correct

4) Aluminum has a density of 2.70 g/ml what volume would be occupied by a block of Al that weighs 4.32 kg?

5) 1000 nutritional calories would equal?

a) 1000 cal

b) 1.000x10^6 cal

c) 1.000 cal

d) 4184 J

6) N2 + 3H2 = 2 NH3 how many moles of N2 will be needed to react with 1.00 mol of H2?

1) CH3COOCH3

C = 4

H = 1

O = 2

total bonding electrons = 22

2) answer = option C = catboxyllic acid

3) answer = option B = lower than weak acid

4) d = mass / volume

volume = mass / density

volume = 4320 g / 2.70 g/mL

volume = 1600 mL

5) option a = 1000 cal

6) 3 mole H2 require 1 mole N2

1.0 mol H2 require 1 / 3 = 0.33 mol N2
