1)Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder has a mass of 306.0 g. From this information, calculate the density of mercury. 2) A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block has a mass of 1587 g. From this information, calculate the density of lead. 3) 28.5 g of iron shot is with a volume of 3.6mL is poured into a pile. From this information, calculate the density of iron. 4) Liquid A has a density of 5 g/mL, Liquid B has a density of 3 g/mL, Liquid C has a density of 7 g/mL, Liquid D had 1 g/mL. Knowing this if these liquids were mixed, list the order of the layers they would settle in from top to bottom.

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

The image seems to be behind the mirror, but nothing is really there.just took the test.
