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%.

Answer:
Lies predominantly to the left.
Explanation:
In the reaction:
NH4⁺(aq) + Br-(aq) ⇄ NH3(aq) + HBr(aq)
Conjugate acid + Ion ⇄ weak base + strong acid
HBr is a strong acid whereas NH3/NH4⁺ are the weak base and its conjugate base. A strong acid as HBr dissociates completely in solution as H⁺ and Br⁻. That means in solution you will never have HBr without dissociation doing the reaction:
<h3>lies predominantly to the left.</h3>
Answer: hope this is hopeful
Explanation:
1.So, potassium atom is bigger than sodium atom.
2.Sodium: The valence electron of sodium is in the 3s orbital. Potassium: The valence electron of potassium is in the 4s orbital. Atomic Size. Sodium: Sodium atom is
3. • While excess of sodium is harmful for us, low levels of potassium have also been found to be associated with certain disorders of lungs and heart.

This is an example of convection
