2.<span> It's important to know your blood type because it prevents the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery. If two different blood types are mixed, it may lead to a clumping of blood cells that can be potentially fatal.</span>

Answer:
The Kelvin temperature scale reflects the relationship between temperature and average kinetic energy.
Explanation:
The Kelvin temperature of a substance is directly equal to the average kinetic energy of the particles of a substance.
<span>Question: Organic chemistry is the study of compounds containing?
Answer: (A) Carbon
Organic chemistry is the study of compounds that contain the element carbon, or the study of carbon-containing molecules and the compounds they form. An entire branch of chemistry (carbon chemistry) is dedicated to this subject. Which means carbon is quite important, after all it is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and Organic compounds together scientists can learn more about life, the human body, and how it works!</span>
Answer:
The answer to your question is 203.8 g
Explanation:
Data
Average atomic mass = ?
Centium-200
Centium-203
Centium-209
Equal amounts
Process
1.- Determine the abundance of each isotope.
If they are in equal amounts in nature, just divide 100 by 3
100/3 = 33.33 % or 0.333
2.- Determine the Average atomic mass
Average atomic mass = Atomic mass 1 x abundance + Atomic mass 2 x
abundance + Atomic mass 3 x abundance
- Substitution
Average atomic mass = 200 x 0.333 + 203 x 0.333 + 209 x 0.333
- Simplification
Average atomic mass = 66.6 + 67.6 + 69.6
Result
Average atomic mass = 203.8 g
