The main reason for the observed trend is that Explain your reasoning. additional oxygen atoms draw electron density away from more electrons in the valence shell add electron density to more electronegative elements weaken atoms with a larger atomic radius weaken

A1.5l container holds p.50 grams of an unknown gas at a pressure of 0.44 atm and a temperature of 50.c what is the molar mass of the unknown gas

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?
