Which type of matter is composed or two or more elements that are chemically combined in a fixed proportion?
1 answer:
Hello.
When dealing with two or more elements in a fixed proportion, your answer is going to be "B.) Compound." The explanation is pretty basic when you narrow it down - think of it like the English version of a compound sentence; there are two independent clauses that have related ideas (such as this one, for example).
Let's use an example of a compound element, such as
, or Water.
This is a compound element that is composed of the two elements "Hydrogen" and "Oxygen" - for every 2 Hydrogen atoms there is one Oxygen atom.
I hope this helps!

Answer:
The age of the sample is 4224 years.
Explanation:
Let the age of the sample be t years old.
Initial mass percentage of carbon-14 in an artifact = 100%
Initial mass of carbon-14 in an artifact =
Final mass percentage of carbon-14 in an artifact t years = 60%
Final mass of carbon-14 in an artifact =
Half life of the carbon-14 =
Solving for t:
t = 4223.71 years ≈ 4224 years
The age of the sample is 4224 years.
