Answer:
Yes.
Explanation:
Yes, I agree with Bryce and his lab partner because titration is completed when the solution changes its colour. Add chemical from the burette until the solution change its colour so then calculate the amount of chemical is used from the burette and the time at which the titration is completed. Always be careful for calculating the titration in order to get accurate data of the solution.
The mole ratio between sodium bicarbonate and that of acetic acid is 1:1
<h3>What is mole ratio?</h3>
A mole ratio can be defined as that ratio in whole numbers between the amounts in moles of any two compounds involved in a balanced chemical reaction.
- The mole ratio of each individual element is found by dividing the number of moles of each by the smallest number of moles.
In conclusion, the mole ratio between sodium bicarbonate and that of acetic acid is 1:1

A) Answer D. Clouds forming high in the atmosphere are referred to as cirrus, cirrostratus, and cirrocumulus.
B) Clouds tend to form at higher altitudes because as<span> air rises, the moisture in it slowly reaches its saturation point and when this happens, tiny crystals of water start to condense and form clouds.
C) Precipitation: Water that falls to the ground from clouds, such as in rain, snow, sleet, or hail.</span>
Answer:
3.01 × 10^24 atoms of vitamin D
Explanation:
The number of atoms, molecules or ions present in a substance is given by the Avogadro's number which is 6.02 × 10^23.
Hence;
1 molecule of vitamin D contains 6.02 ×10^23 atoms
5 molecules of vitamin D contains 5 × 6.02 ×10^23/1
= 3.01 × 10^24 atoms of vitamin D
