2 NaCl + Pb(NO3)2 --> 2 NaNO3 + PbCl2 How many grams of PbCl2 are produced from the reaction of 12.3 g of NaCl and 40.8 g ofPb(NO3)2? What is the limiting reactant? (2 gram to gram conversions determining g PbCl2) Molar mass of NaCI= 58 g/mol , Molar mass of PbCl2 =277g/mol, Molar mass of Pb(NO3)2= 331 g/mol

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.
