61.0 mL of a solution(1.60 M) is diluted to a volume of 208 mL. A portion of that solution(104-mL) is diluted using 121 mL of H2O. determine the final concentration?
What are the effects of temperature, molarity, surface area, nature of the reactants, and the presence of a catalyst on the reaction rate of Zn(s)+2HCl(aq)-> ZnCl2(aq)+ H2(g)
Disposable lighters burn butane (C4H10) and produce CO2 and H20. Balance the chemical equation for this combustion reaction and determine how many grams of CO2 are produced by burning 1.00 g of C4H10.

Help me understand specifically why the dissociated phosphate ion would prefer to bond with cations like Al and Zn. I think I know why but help me better understand.
Measurements of strontium in enamel from extracted wisdom teeth were done by atomic absorption spectroscopy. Solutions were prepared with a constant total volume
A 0.5 M solution of hydrogen sulfide (H2S) contains 0.15 M nickel chloride NiCl2, and 0.35 M mercury nitrate Hg(NO3)2. The pH of this solution is made very acidic through the use of HCl so that all ions are in solution
