Answer:
A.
Explanation:
In an endothermic reaction heat is applied.
The answer for the following question is explained.
<u><em>Therefore the number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1).</em></u>
Explanation:
Here;
n represents the principal quantum number
l represents the Azimuthal quantum number
m represents magnetic quantum number
s represents spin quantum number
n = 5,
l = 2,
m = -2,
s = +1/2
Here, it implies 5d orbital.
In the 5d orbital, 10 electrons.
As the magnetic quantum number is -2, and so it can have 1 electron.
<u><em>Therefore the number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1)</em></u>
A census is a survey of a complete population and not just a small sample.
You can hold a census of your entire school, your whole city, or the entire state.
A census has to include EVERYONE in the population you want to draw conclusions on. A sample would only include a small number of people from any group. The census must survey all of them.
Answer:
35.4575 amu
Explanation:
We use the relative abundance of each of the isotopes.
Let the isotopes be A and B.
Since A is having an abundance of 75.53, the abundance of B would be 100 - 75.53 = 24.47%
The average atomic mass is calculated as follows;
(75.53/100 * 34.96885) + (24.47/100 * 36.96590) = 26.4119 + 9.0456 = 35.4575 amu
