A chemist fills a reaction vessel with 0.654 g silver chromate (Ag, CrO4) solid, 0.840 M silver aqueous solution, and 0.688 M chromate aqueous solution at a temperature of 25.0° C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction:

Ag2CrO4(s) ---> 2Ag+ (aq) + (CrO4)2- (aq).

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

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.
