Draw the lewis structure of h2o. include any nonbonding electron pairs. draw the molecule by placing atoms on the grid and connecting them with bonds. include all lone pairs of electrons.

The structure of water has 2 atoms of Hydrogen and 1 atom of oxygen.

The hydrogen atom has 1 valence electron and oxygen has 6 valence electrons. The bonding of 2 hydrogens will result in the 2 pair of loan pair to the oxygen atom.

The bonding electrons in the water molecule are 4, 2 of hydrogen and 2 of oxygen. 4 Non-bonding electrons or 2 loan pairs are present in the molecule of water.

The lewis structure for the water is represented in the image attached.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
