Draw a physical model that shows the reaction of zinc metal and hydrochloric acid (hydrogen chloride). Zinc + Hydrochloric Acid → Zinc Chloride and Hydrogen Gas

Zn + 2HCl → ZnCl2 + H2

Be sure to label your model to clearly show how you are representing the atoms, how they are rearranged and that mass is conserved in the reaction.

I don't need it drawn, if you can just explain to me the reaction and what happens i can draw it. Please?

Anurse used a 0.02-mg/l solution of disinfection to clean a patients wound. what is the concentration of the solution expressed as a percentage?

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
