How many kilojoules of heat are released when 32.0 g of naoh are dissolved in water? (the molar heat of solution of naoh is –445.1 kj/mol.)

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
