Chlorobenzene would essentially be a benzene ring that is substituted with chlorine. Thus it would have 6 carbon atoms, in its molecular formula.
Answer: Option (C) is the correct answer.
Explanation:
A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.
Basically in a neutral atom electrons are present in their parent shell.
For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is 
.
Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.
Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.
The answer to the question is B D E
Answer:
D. increase of carbon dioxide
Explanation:
Breathing is automatic and is controlled subconsciously by respiratory center at base of brain. It continues during the time of the sleep and even when the person is not in conscious. Sensory organs in brain and in aorta and the carotid arteries monitor blood and sense the oxygen and the carbon dioxide levels. <u>Usually, increased concentration of the carbon dioxide is the strongest stimulus for the breathing to occur more deeply and more frequently. </u>
When carbon dioxide concentration in the blood is high, the brain increases the frequency and the depth of breaths.
