Sodium. Oxygen is electronegative and hece pulls bonding electron towards oxygen atom, creating a partial negative charge on the oxygen atom. As unlike charges attract, it is then attracted to the positively charged sodium ion.

In this situation, the oxygen atoms of the water molecules would be attracted to the sodium atoms from the sodium chloride because oxygen has a charge of -2 and sodium has a charge or +1 (opposite signs attract).

Answer: circle graph.

Justification:

A circle graph (also known as pie chart) is excellent to visualize the relative size of different sectors. Being the entire circle 100%, each sector will show the percent of each category.

In the given example, the circle will be divided in 3 different sectors, in which the size is proportional to the percent of each one.

In the given case:: 

<span>pH less than 8: 20%
</span><span>
</span><span> pH between 8 and 8.5: 50%,
</span><span>
</span><span>pH greater than 8.5: 30%
</span><span>
</span><span>
</span><span>So, a sector whose area is 20% will represent the first category, a sector whose area is 50% will represent the second category, and a sector whose area is 30% will represent the third category. The whole circle is 100%, this is the sum of the 3 categories is 100%.

Andru [333]

Answer:

{ \rm{2\: moles  \: of \: sodium \: chlorate = 2 \: moles \: of \: sodium \: choride}} \\ { \rm{10 \: moles \: of \: sodium \: chlorate = ( \frac{10}{2}  \times 2) \: moles}} \\  \\  = { \boxed{ \rm{ \: 10 \: moles \: of \: sodium \: chloride}}} \\
