When nickel metal is added to a beaker of HCl(aq), a gas is produced. Knowing that nickel is oxidized and that hydrogen is reduced, write the balanced net equation for the reaction. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.) chemPadHelp How many electrons are transferred in the balanced equation

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.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
