Since the atomic mass is an average of the masses of all isotopes of that element, you have to consider which isotope is most abundant. In this case, the atomic mass is closest to twelve, so the most abundant isotope of carbon is Carbon 12.
Answer:
Observing and questioning
Explanation:
The Scientific Method:
- Observe
- Question
- Hypothesis
- Experiment
- Collect Data
- Analysis
- Conclusion
This is because its forward momentum is greater when it goes faster, therefore it requires more force/friction to slow it down to a halt.
Answer is: near equivalence point indicator should change color, so we must pick indicator who changes color near pH of equivalence point.
Equivalence point is
the point which there is stoichiometrically equivalent amounts of acid and
base. <span>

showing the change in pH of a solution, which is being titrated) for
titration and determine equivalence point.</span></span>
