Water molecules are ____________ because the hydrogen atoms are positively charged on one end and the oxygen atoms are negativel
y charged on one end. Molecules that are ____________ share electrons equally. Sodium chloride (NaCl) is an example of a ____________ molecule because it is soluble in water. Molecules that are ____________ are insoluble in water. It is ____________ that most molecules formed with nonpolar bonds dissolve easily in water.

First, place no. 5 in front of the CO2 in order to balance the carbon atoms. Next, place no. 6 in front of H2O to balance the hydrogen atoms. Lastly place no. 8 in front of the O2 so that there are 16 oxygen atoms on both sides of the reaction.
