Help me ASPAP

Explanation:

1.  H2O

Lewis Dot:  

See the attachment.

Note the б+ and б- signs on the H and O atoms, respectively.  Those represent the slightly positive and slightly negative sides of the water molecule.  Those slight charges on a single water molecule are attracted to their opposite charges on neighboring H2O molecules, as shown in the graphic.  This interaction is what gives water it's cohesive properties.

3.  The property of cohesion describes the ability of water molecules to be attracted to other water molecules. which allows water to be a "sticky" liquid.

The hydrogen bonds are attractions of electrostatic force.  They arise due to the difference in charge between the slightly positive hydrogen ion and the slightly negative oxygen ion. Hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond, and it is what gives water it's cohesiveness, or ability to support water spiders, paper clips, and produces a loud noise in the event of a belly flop in a pool (including the yelp from the swimmer).

4.  I'm not sure what is being asked for the two blanks.  Water is polar and dissolves salts (ionic compounds) and hydrophilic molecules (water-loving molecules).

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

58750.08068 is the answer i think
