Answer:
9.3 x 10^ -5 in standard notation is 0.000093
Explanation:
Since 10 is raised to a -5, this means that there should be 5 zeros before the non-zero digits
Answer:
Explanation:
First thing is we have assume all the percents are grams so we have
68.279g C, 6.2760g H, 3.7898g N, and 21.656g O
Now convert each gram to moles by dividing the the molar mass of each element
68.279g/12.01g= 5.685 moles of C
6.2760g/1.01g= 6.214 moles of H
3.7898g N/14.01g= 0.271 moles of N
21.656g O/ 16.00g= 1.354 moles of O
Now to find the lowest ratios divide all the moles by the smallest number of moles you found, in our case, the smallest moles is 0.271 moles of N so divide everything by that....
5.685 moles/0.271 moles ------> ~21 C
6.214 moles/0.271 moles --------> ~23 H
0.271 moles / 0.271 moles ---------> 1 N
1.354 moles/ 0.271 moles ----------> ~5 O
So the empirical formula is C21H23NO5
Jupiter weather phenomena that are similar to those in earth. The lighting storms which have been discovered in jupiter's atmosphere...

Quantum numbers are the conserved quantities in the system that expresses the position of the electron. The second quantum number describes the electron subshells.
<h3>What are quantum numbers?</h3>
Quantum numbers are the energy and the position defining values of the electron in the atomic structure. There are four basic quantum numbers, principal, magnetic, azimuthal, and spin quantum.
The second quantum number (I) is the angular quantum number that describes the magnitude of the subshells (s,p, d, and f) or the type of the subshells. It is also known as the Azimuthal quantum number.
Therefore, the second quantum number shows the electronic subshells.
