Calculate the qsp or ksp, as indicated, and determine whether a precipitate will form when each of the following mixtures is prepared. (you may assume temperature is held constant, volumes are additive, and that the initial solutions, prior to mixing, are unsaturated.) (a) 25.30 ml 1.48 ✕ 10−4 m cacl2 is mixed with 25.16 ml 3.02 ✕ 10−3 m naf. (ksp for caf2

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.

Acertain atom has 22 protons and 19 electrons. this atom loses an electron. the net charge on the atom is now 4+1+01-4-. if this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be 3+2+02-3-.
