The density of air at sea level and 25°C is about 1.2 kg/m3 (1 m3= 1000 dm3= 1000 L) Out of the following balloons,

A Red Balloon with a volume of 3.5 *104 mL and a mass of 6.25*10-3 kg

A Blue Balloon with a volume of 4 liters and a mass of 7.14 g

A Green Balloon with a volume of 100 cm3 and a mass of 0.32 g

1. The (pick one) balloon would be most likely to float in air.

2. The density of Chlorine gas is 3.2 g/L. The balloon that is most likely to contain chlorine gas is the (pick one) Balloon.

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.

This chart lists four kinds of polymers and their sources. what can be known about all four polymers, despite their differences? they come from living things. they share ionic carbon bonds. they are at least 100 monomers long. they are made of repeating subunits.

Energy defines the different "states" of matter. in no more than 3 sentences, describe the amount of kinetic energy that each of the 3 states of matter possesses and relate that to the atom/molecular motion of each "state".
