A 1.000 L vessel is filled with 2.000 moles of
N2, 1.000 mole of H2, and 2.000 moles of NH3.
When the reaction
N2(g) + 3 H2(g) ββ½ 2 NH3(g)
comes to equilibrium, it is observed that the
concentration of H2 is 1.97 moles/L. What is
the numerical value of the equilibrium constant Kc

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point
