Answer: left and right hemisphere ya
Explanation:
Complete question:
Write the condensed formula from left to right, starting with (CH3)x where x is a number.
See attached image for the structure formula of the compound
Answer:
(CH₃)₂CHC(CH₃)₃ named as 2,2,3-Trimethylbutane
Explanation:
If we number the longest chain of the carbon starting from the left, we will observe that there are four carbons in the straight chain as shown in the image.
Starting from first carbon from the left of the carbon chain, at carbon number number 2, there two alkyl group, that is two methyl (CH3 is two). Also at carbon number 3, there are three alkyl group, that is three methyl (CH3 is three).
The condensed formula will be written as;
(CH₃)₂CHC(CH₃)₃
This compound is named as 2,2,3-Trimethylbutane, an isomer of Heptane
If an emergency vehicle passes you in traffic, just as it passes you the pitch of the siren changes as it approaches, the siren’s pitch sounds higher than when it is moving away from you.the frequency increases as the siren is moving toward you, and decreases as it is moving away, is correct
This change is a common physical demonstration of the Doppler effect.
<h3>What is Doppler effect ?</h3>
This effect refers to the increase in the frequency of sound, as the source and observer move toward (or away from) each other.
The effect causes the sudden change in pitch noticeable in a passing siren.
Hence Option (B) i.e, the frequency increases as the siren is moving toward you, and decreases as it is moving away, is correct
