the heat of vaporization of water at 100°c is 40.66 kj/mol. calculate the quantity of heat that is absorbed/released when ""7.00"" g of steam condenses to liquid water at 100°c.

How have the greenhouse gasses increased from the year 2000 to 2018

Adilute aqueous potassium nitrate solution is

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)
