How many electron pairs exist in single bonds double bonds and triple bonds?

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

In which phase(s) do the molecules take the shape of the container?
