1. Ms. Smith left the ice cream out long enough that it melted. She wasn't concerned though as she knew that it would be okay once it was put back into the freezer. She knew this because she remembered that a. removing; move faster badding; move slower C. removing; move slower energy causes particles to , allowing the ice cream to solidify. Gold has a density of 19.32 g/cm³, Quartz has a density of 2.64 g/cm³ and Copper has a density of 8.92 g/cm. While digging in the backyard, you find an object that has a mass of 26.76 g and a volume of 3 cm. If density is mass divided by volume, what substance did you find? 2. a. Copper b. Gold C. Quartz Randy was helping his dad rake and burn the leaves in their yard this fall. He asked his dad why there was nothing, but ashes left once the leaves were burned. His dad explained that this was a change that occurred and caused the matter in the leaves to turn into a different kind of matter. He said this was because the leaves had flammability which is a ....... 3. a. physical change b. physical property C. chemical change d. chemical property

During the discussion of gaseous diffusion for enriching uranium, it was claimed that 235UF6 diffuses 0.4% faster than 238UF6. Show the calculation that supports this value. The molar mass of 235UF6 = 235.043930 + 6 ×18.998403 = 349.034348 g/mol, and the molar mass of 238UF6 = 238.050788 + 6 × 18.998403 = 352.041206 g/mol.

Let's say you blew three baloons to the same size and left one baloon at room temperature, and kept one baloon in an ice bath, and one baloon above a hot water container. You left the laboratory for 30 minutes and when you came back, you saw that the size of the baloon in the ice bath was smaller than before and size of the baloon above hot water container was larger than the original size. As chemistry student, how do you explain the reason for this observation.
