The correct answer option is A) benzene.
<u>Explanation:</u>
Benzene is an organic chemical compound (hydrocarbon), consisting of 6 carbon atoms and 6 hydrogen atoms.
Out of all the given options, Benzene will solidify the earliest before reaching a temperature of 0 degree Celcius, when cooled.
The reason being that it has a freezing temperature of 5.5 degree Celcius while all other substances have their freezing points which are below 0 degree Celcius.
I'd recommend checking out some videos on youtube to get some good examples worked out, for example, the video "<span>How to Balance Chemical Equations in 5 Easy Steps: Balancing Equations Tutorial" is done well.</span>
Answer: all atoms of the same element have the same atomic number.
Explanation:
atomic mass differentiates them, which is the same as the mass number.
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%.

They have began to grow apart, as their lives are changing and as they are growing older, they are growing further apart.
I would say the answer is B - Differentiating
