In the reaction
2k + 2h20 - 2koh + h2, which compound has an element ratio of 1: 1: 1

a) кон
b) h2
c) k

a) KOH

Explanation:

In the given balanced reaction

                         2K + 2H2O → 2KOH + H2

In the compound KOH,

The elements are K,O, and H and in the compound, there is one mole each of K , O ,and H.

So the element ratio here is 1 : 1 : 1.

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.
