Answer:
<u>1)Thus based on the diagram , the values of principle quantum number that can be assigned to the electrons are : 2,3 and 4.</u>
<u>2)This quantum number tells us the shell in which an electron is present and how far it is roughly from the nucleus.</u>
Explanation:
According to the rules of electron filling in subshells in quantum mechanics , <em>Aufbau's principle states that :</em>
<em>"An electron must be filled in a lower energy state or subshell and then higher. If they have the same energy , the one with lesser principal quantum number will be filled first."</em>
Thus ,
The series of filling goes like:
Thus , the subshells in the given information have 1,3 and 1 orbitals respectively. Thus it has to be which is possible in two cases :
1)Thus based on the diagram , the values of principle quantum number that can be assigned to the electrons are : 2,3 and 4.
2)This quantum number tells us the shell in which an electron is present and how far it is roughly from the nucleus.
There are 11 Carbon atoms in the compound.
<u>Solution:</u>
Carbon atom count is the ratio of the M peak to the M+1 peak.
Here M peak is 57.10% and M+1 peak is 6.83%. On applying the values in the formula we get,
Therefore, the number of Carbon atoms in the compound are 11.
Refer the image attached below for a better understanding of M peak and M+1 peak.
The heaviest ion that has the greatest m/z value is said to be the molecular ion peak in mass spectrum.
Ideal Gas Law equation: PV= nRT
⇒ V= nRT/ P
⇒ V= (1.50 mol)* (0.08206 L*atm/ (K*mol))* 273 K/ 1.00 atm= 33.6 L.
The final answer is 33.6 L.

It should be 8 O atoms. 3O atoms in Na2S2O3 and 5O atom in 5H2O. The reason there are 5 O atoms are because the 5 in front of H2O means you multiply each atom in the compound by that number (like the distributive property). The H2 molecule becomes 10 Hydrogen atoms (5*2) and the Oxygen becomes 5 Oxygen atoms (5*1). Then you add the 5O atoms to the 3O atoms which equals 8
Answer:
The Answer is option D
Explanation:
The nucleus of a radioactive element is unstable. The nucleus will break down over time, reducing the amount of the element remaining.
