When you initially standarized your NaOH sollution, you diluted your HCl stock solution and added water to it. If you used 24.8 ML of 0.18 M HCl stock solution and added another 26.2 mL of water, what is the new molarity of the acid?
why is it easier to analyze a mixture of atomic species by absorption spectroscopy than it is to analyze a mixture of molecular species?
write the balanced chemical equation for each of the following equilibrium constant expressions: a)Kc=[CO2][H2]/[CO][H2O. b)Kc=[H2][F2]/[HF]^2. c)Kc=[O2][HCl]^4/[Cl2]^2[H2O]^2. d)Kc=[CS2][H2]^4/[Ch4][H2S]^2.
Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.
