Fill in the missing reactant and then balance each equation. k(s) + → koh(aq) + h2(g) k (s) + 3h2o →2koh (aq) + 2h2 (g) bi(no3)3(aq) + → bi2s3(s) + hno3(aq) hno3(aq) + → ba(no3)2(aq) + h2o(l)

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible?

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
