Answer:
60 mph (miles per hour)
Explanation:
0.5 hours is 1/2 of an hour, so to get the number of miles for a whole hour you multiply the miles ran by 2.
30 times 2 is 60.
Answer:
The answer to your question is: letter D
Explanation:
A. a motile archaea Archea don't have peroxisomes then this option is wrong.
B. a nonmotile eukaryote The new organism has flagella then it can move, so this option is wrong.
C. a motile bacterium Bacterium don't have peroxisomes so this option is wrong.
D. a motile eukaryote This is the correct option because an eukaryote can have all the characteristics described.
Answer :
- <u>Part A :</u> The given unbalanced redox reaction is,
![NH^+_4+MnO^-_4\rightarrow NO^-_3+Mn^{2+}](https://tex.z-dn.net/?f=NH%5E%2B_4%2BMnO%5E-_4%5Crightarrow%20NO%5E-_3%2BMn%5E%7B2%2B%7D)
Now we have to balance the given redox reaction in acidic medium by half reaction method.
1st half reaction : ![8H^++MnO^-_4+5e^-\rightarrow Mn^{2+}+4H_2O](https://tex.z-dn.net/?f=8H%5E%2B%2BMnO%5E-_4%2B5e%5E-%5Crightarrow%20Mn%5E%7B2%2B%7D%2B4H_2O)
2nd half reaction : ![3H_2O+NH^+_4\rightarrow NO^-_3+10H^++8e^-](https://tex.z-dn.net/?f=3H_2O%2BNH%5E%2B_4%5Crightarrow%20NO%5E-_3%2B10H%5E%2B%2B8e%5E-)
For net balanced reaction, 1st half reaction is multiplying by 8 and 2nd half reaction is multiplying by 5
The net balanced redox reaction is,
![8MnO^-_4+14H^++5NH^+_4\rightarrow 8Mn^{2+}+17H_2O+5NO^-_3](https://tex.z-dn.net/?f=8MnO%5E-_4%2B14H%5E%2B%2B5NH%5E%2B_4%5Crightarrow%208Mn%5E%7B2%2B%7D%2B17H_2O%2B5NO%5E-_3)
- <u>Part B :</u> The given unbalanced redox reaction is,
![Cr(OH)_3+ClO^-_3\rightarrow CrO^{2-}_4+Cl^-](https://tex.z-dn.net/?f=Cr%28OH%29_3%2BClO%5E-_3%5Crightarrow%20CrO%5E%7B2-%7D_4%2BCl%5E-)
Now we have to balance the given redox reaction in basic medium by half reaction method.
1st half reaction : ![Cr(OH)_3+H_2O+5OH^-\rightarrow CrO^{2-}_4+5H_2O+3e^-](https://tex.z-dn.net/?f=Cr%28OH%29_3%2BH_2O%2B5OH%5E-%5Crightarrow%20CrO%5E%7B2-%7D_4%2B5H_2O%2B3e%5E-)
2nd half reaction : ![ClO^-_3+6H_2O+6e^-\rightarrow Cl^-+3H_2O+6OH^-](https://tex.z-dn.net/?f=ClO%5E-_3%2B6H_2O%2B6e%5E-%5Crightarrow%20Cl%5E-%2B3H_2O%2B6OH%5E-)
For net balanced reaction, 1st half reaction is multiplying by 2.
The net balanced redox reaction is,
![2Cr(OH)_3+ClO^-_3+4OH^-\rightarrow 2CrO^{2-}_4+Cl^-+5H_2O](https://tex.z-dn.net/?f=2Cr%28OH%29_3%2BClO%5E-_3%2B4OH%5E-%5Crightarrow%202CrO%5E%7B2-%7D_4%2BCl%5E-%2B5H_2O)
There are four quantum numbers for an orbital, namely, principal quantum number n, azimuthal quantum number l, magnetic quantum number
and spin quantum number s. No two orbitals can have same value for all the four quantum numbers.
Principal quantum number tells about the position of orbital that is shell number, azimuthal quantum number describes the shape of orbital, for s, p, d, f,... orbitals, the value is 0, 1, 2, 3,... so on. The value of magnetic quantum number varies from -l to +l (including zero), it defines the sub shell of electron. Spin of the electron defines its movement that is clockwise or anticlockwise thus, there are only two possible values for spin quantum number: +1/2 or -1/2.
For 2p orbital, principal quantum number n is 2 (denotes the shell) and azimuthal quantum number for p orbital is 1. Thus, different values for magnetic quantum number will be -l to l that is -1, 0,1.
Therefore, for 2p subshell there are 3 different
values.
