How does the structure of water explain the physical and chemical properties of water?

The structure of a water molecule shows that it is polar since oxygen is big and there are two small hydrogen atoms bonded to it. It shows the physical property by showing how it can attatch and create cohesion between other water molecules.

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.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
