Calcium chloride has a heat of solution listed as -81.3 kJ/mol when dissolved in water. Using this, suppose we dissolve 10.0 g of calcium chloride in 50.0 mL of water at 25 degrees Celsius. What will be the new temperature of the water? (assume that Csolution = 4.18 J/g degrees Celsius)

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.

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
