<u>Answer: </u>One isotope has a percentage abundance of 75.75 % and the percentage abundance of another isotope is 24.24%.
<u>Explanation:</u>
We are given the two stable isotopes of chlorine with their respective masses. The average atomic mass of chlorine is also given.
Average atomic mass of chlorine = 35.45 amu.
Let us assume the fractional abundance of one isotope be 'x' and the fractional abundance for another isotope will be (1 - x) because the total fractional abundance is always equal to 1.
Fractional abundance = x
Mass = 34.97 amu
Fractional abundance = 1 - x
Mass = 36.95 amu
The formula for the calculation of average atomic mass is given by:
Putting values in above equation, we get:
Converting these two fractional abundances into percentage abundances by multiplying it with 100.
Hence, one isotope has a percentage abundance of 75.75 % and the percentage abundance of another isotope is 24.24%.
Answer:
Image result for Which hydrogen is an unsaturated hydrocarbon ?
Alkenes have the general formula CnH2n, and are examples of unsaturated hydrocarbons. The presence of a double bond compound's structure causes there to be two fewer hydrogen atoms in the molecule than there are in an alkane with the same number of carbon atoms.
Answer:
All of the above
Explanation:
Molecules make up matter so they are considered matter as well.

Explanation:
The pH is larger than 7.
The relationship between pH and pOH is
pH + pOH = 14
if something is base, it's pH is greater than 7.
it's pOH is between 0 and 7.
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
