Water is a polar molecule, meaning it carries partial charges ( δ + or δ − ) on opposite sides of the molecule. For two formula units of NaCl , place the sodium ions and chloride ions where they would most likely appear based on the grouping of the water molecules in the areas provided. Note that red spheres represent O atoms and white spheres represent H atoms.

The sodium molecules (Na +) will side with the Oxygen molecules (O-), while the chlorine molecules (Cl-) will side with the hydrogen molecules (H +).

Explanation:

As you know, NaCl is a polar substance, since it can establish ionic bonds with a water molecule (H2O), allowing it to be completely dissolved by it.

As you may already know, the water molecule has an electronic gradient. This is because the oxygen molecule is very electronegative, pulling the two hydrogen molecules, fortiment. This causes the water molecule to create poles: a negative pole on the oxygen side and a positive pole on the hydrogen side.

When NaCl comes into contact with water, positive Na + molecules are attracted to the negative pole of the water molecule, while negative Cl- molecules are attracted to the positive pole of the water molecule.

if kj of heat is transferred o 1200 g liquid water at 36'c, what would the new temperature of the water be? (he specific heat capacity of liquid water is 4.186 j/g''c)

a. 15'c

b.100'c

c.51'c

d.36'c

hi,

henry is an economist and wants to understand the relationship between inflation and consumer spending habits. for his research, he needs the consumer price index for 2014 and the inflation rate. based on the prices of goods given, what will he find to be the cpi and inflation rate for 2014? assume that a consumer’s basket for three consecutive years consists of the following:

you dont privide answer choices.

answer - 15% of a inflatation rate is 15% less in cpi
