2) A solution consists of 0.50 mole of CaCl2 dissolved i 100. grams of H20 at 25°C. Compared to the boiling
point and freezing point of 100. grams of H20 at
standard pressure, the solution at standard pressure
has
(A) a higher boiling point and a lower freezing
point
(B) a lower boiling point and a lower freezing point
(C) a lower boiling point and a higher freezing
point
(D) a higher boiling point and a higher freezing
point
3) Which solution has the highest boiling point at

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.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
