Water

how many oxygen atoms are in a molecule of water?

1

how many hydrogen atoms are in a molecule of water?

2

maximum number of bonds that one molecule can share is...

4

where is the majority of negative charge on the water molecule?

Around the oxygen

what do the solid lines between the small and large circles represent?

Covalent bond

Hypotonic

Having a lower concentration of solute than another solution

Hypertonic

More dissolved stuff; less water

what kind of charge would the oxygen atom have compared to the hydrogen atom?

Negative

what kind of charge would the hydrogen atom have compared to the oxygen atom?

Positive

What arrangement of electrons would result in a nonpolar molecule?

The bonding in the molecules have to be equally shared between the atoms

What type of molecules make up water?

The scientific term for water is H2O. This means that in each water molecule there is two hydrogen atoms and one oxygen atom.

Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances interact with water?

They cannot mix

capillary action

adhesion of water to glass (or paper etc) that causes water to rise against gravity

What kind of charge would the hydrogen atoms have compared to the oxygen?

higher positive charge

the small unshaded circles in model 2 are?

hydrogen

describe the arrangement of the water molecules in model 2 with one another

hydrogen atom is attracted other atom of water molecules

Why is water good for you?

keeps you hydrated, flushes fat, helps liver and kidney function.

describe the cause of the attractions between molecules of water

opposite charges atract

How many hydrogen atoms are in a molecule of water?

two

according to model 2 what is represented by the dotted lines?

weak attraction
