Explanation:
A normal model is represented as (μ, σ). Therefore for (1.5, 0.18), the mean (μ) = 1.5 and the standard deviation (σ) = 0.18
The z score shows by how many standard deviations the raw score is above or below the mean. It is given as:
a) For x < 1.35 s
From the normal distribution table, the percent of drivers have a reaction time less than 1.35 seconds = P(x < 1.35) = P(z < -0.83) = 0.2033 = 20.33%
b) For x > 1.9 s
From the normal distribution table, the percent of drivers have a reaction time greater than 1.9 seconds = P(x > 1.9) = P(z > 2.22) = 1 - P(z<2.22) = 1 - 0.9868 = 0.0132 = 1.32%
c) For x = 1.45
For x = 1.75
From the normal distribution table, P(1.45 < x < 1.75) = P(-0.28 < z < 1.39) = P(z < 1.39) - P(z< - 0.28) = 0.9177 - 0.3897 = 0.528 = 52.8%
d) A percentage of 10% corresponds to a z score of -1.28
e) P(z < z1) - P(z< -z1) = 60%
P(z < z1) - P(z< -z1) = 0.6
P(z < -z1) = 1 - P(z < z1)
P(z<z1) - (1 - P(z < z1)) = 0.6
2P(z<z1) - 1= 0.6
2P(z<z1) = 1.6
P(z<z1) = 0.8
From the z table, z1 = 0.85
The reaction time between 1.35 and 1.65 seconds
Answer:
1s² 2s²2p³
Explanation:
If the atom has seven electrons, it is Element 7 (nitrogen).
In the Periodic Table, you count the electrons in all the subshells up to
No. 7.
In the first Period, you have filled the 1s level (2 electrons).
In the second Period, you have filled the 2s subshell (2 electrons) and put three electrons in the 2p subshell.
Thus, the electron configuration is
1s² 2s²2p³
Note how the superscripts tell you the number of electrons in each subshell: <em>2 + 2 + 3 = 7</em>.
C₆H₅NO₂
<h3>Further explanation</h3>Nitrobenzene contains:
- 5 hydrogen atoms,
- 6 carbon atoms,
- 2 oxygen atoms, and
- 1 nitrogen atom.
The chemical formula for nitrobenzene is C₆H₅NO₂.
Nitrobenzene is one of benzene derivatives, precisely including the type of monosubstituted benzenes.
The molecular structure of phenyl is formed by removing one H atom from the benzene
molecule. A substituent is bound to the C atom which loses the H atom so it is called monosubstituted benzene.
In the naming of monosubstituted benzenes, benzene is the parent name and the substituent is indicated by a prefix.
- nitro is the substituent
- benzene is the parent name
When benzene is reacted with a mixture of concentrated nitric acid and concentrated sulfuric acid, it yields nitrobenzene.

<u>Notes:</u>
- Benzene and compounds having similar chemical properties to benzene are called aromatic compounds.
- Benzene is a colorless, poisonous liquid with a specific odor. it dissolves in organic solvents in organic solvents such as alcohol, ether, and acetic acid. Benzene is also good for non-polar substances.
- Nitrobenzene is used in the manufacture of aniline and other organic chemicals. Nitrobenzene is a pale yellow, oily, and highly toxic liquid with the odor of bitter almonds.
