Which statement best describes why a solution of 6.00 g of Ca(NO3)2 in 30.0 g of water has a greater boiling-point elevation than a solution of 3.00 g of Ca(NO3)2 in 60.0 g of water? Question 3 options:

The solution with the higher molality will have the higher boiling point.

The solution with the lower molality will have the higher boiling point.

The solution with more moles of Ca(NO3)2 will have the lower boiling point.

The solution with fewer moles of Ca(NO3)2 will have the higher boiling point.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
