Alvap, water = 40.7 kJ/mol A sample of water has a mass of 100.0 g.
Calculate the amount of heat required to change
the sample from ice at 45.00°C to water vapor at
175.0°C. Relevant constant values are given to the
right
AHius, water = 6.01 kJ/mol
Ср. vapor =
= 1.84 J/g. °C
KJ
DONE
Cp, liquid = 4.18 J/g•°C
Cp, ice = 2.09 J/g. °C
molar mass of water = 18.00 g/mol

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
