Carbon tetrachloride was widely used for many years as a solvent until its harmful properties became well established. carbon tetrachloride may be prepared by the reaction of natural gas (methane, ch4) and elemental chlorine gas in the presence of ultraviolet light. write the unbalanced chemical equation for this reaction. (hcl is a product of this reaction. omit states-of-matter from your answer.)

3.09 lab: reaction of metals 1 which combinations of substances resulted in a chemical change? for each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. make a general statement about the reactivity of the metals in this experiment.
