Are hydrogen bonds formed between all molecules? No because hydrogen can only form these bonds with oxygen atoms.
No because hydrogen can only form these bonds with highly electronegative atoms.
Yes because hydrogen can easily form bonds with atoms that have a neutral charge.
Yes because hydrogen can form these bonds with weakly electronegative atoms.

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
