Question- To ensure that do not provide customers with substandard product, the local steel mill has instigated a quality control program using flame AAS. two of the trace elements they wish to monitor, Al and Ti, form stable oxides. Is this a potential problem for the analysis and, if so, can something be done so the analysis can still be performed?
Not confident which formulas/units I require to solve something like this
A 25.0 mL sample of 0.400 M NH3(aq) is titrated with 0.400 M HCl(aq). What is the pH at the equivalence point. (Kb of NH3 = 1.8 ´ 10-5)
if 18.6 of 0.800 solution are needed to neutralize 5.00 of a household ammonia solution what is the molar concentration
Combustion of a 0.1000 g sample of a compound containing only carbon, hydrogen, and oxygen in excess yields 0.1953 g CO2, and 0.1000 g H2O. A separate experiment shows that the molar mass is 90 Daltons. Calculate the mass percent composition.
What is the % yield of the reaction. Also what will happen if you place two electrodes in a solution of your product and connect the electrodes to the battery. What will occur
A 65.25 g sample of CuSO4•5H2O (M = 249.7) is dissolved in enough water to make 0.800 L of solution. What volume of this solution must be diluted with water to make 1.00 L of 0.100 M CuSO4
What are the highest and lowest possible energy of a photon that can be emitted by a hydrogen atom
