Consider the combustion of propane: C3H8 + 502 - 4 H2O + 3 CO2 AHzn =-2221 kJ/mol Cindy and her lab partner Lou have no clue what to do in their lab and are mimicking Billy and Susie. If Cindy and Lou have 1050 g of
propane (23.8 moles), calculate how much heat energy can they produce by burning their propane. Is that enough to melt their unobtanium?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
