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%.

The final volume of the balloon is 84.75 ml
<u><em>calculation</em></u>
The volume is calculated using Charles law formula
that is V1/T1= V2/T2 where,
V1= 5.00 x10^2 ml
T1= 22.0 °c into kelvin = 22 + 273 = 295 K
V2= ? ml
T2 =0.500 x 10^2 K
make V2 the subject of the formula by multiplying both side by T2
V2 is therefore = T2V1/T1
V2 = (0.500 x 10^2 K x 5.00 x10^2 ml) / 295 K = 84.75 ml
Kinetic
Kinetic - energy in motion
Potential - energy being stored
M(Na2CO3•10H2O)=23*2+12+16*3+180=286g/mol
So lets take 1 mol of this compound
m(comp)=286 gram
m(H2O)=180 gramm
w(h2o)=180/286=0.6293(62.93%)
Answer 62.93% water
