23) _Zn +_Pb(NO2),
What is the balanced equation to this formula?

All the coefficients are 1

Explanation:

This equation is already balanced, but for future problems my chem teacher taught us by using a T-chart for product side and reactant side so we could see easier how to guess and check

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.
