Consider the reaction of zinc metal with hydrochloric acid, hcl() write the molecular equation for this reaction, then balance the equation.(b) calculate the moles of hcl needed to react completely with 8.25 moles of zinc.(c) calculate the grams of zinc chloride produced if 0.238 grams of zinc react completely.

a) Zn+HCL = ZnCl+ H2O

single replacement for the others its basic calculations based on the grams given

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
