SEP Analyze Date Look at Figure 1. In summer, at which depth, A, B, or C, is the water likely to be (a) most dense? (b) least dense? Explain why this is so in
terms of the spaces between molecules. (Hint: Think about where the water is
the coldest as a lake freezes.) Use what you know about kinetic molecular theory
in your answer.

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
