Answer:
Hello dear,
● Benzene to benzaldehyde -
There are several ways to convert benzene into benzaldehyde.
1) Riemer-Tiemann reaction -
- In this reaction, benzene is converted to benzaldehyde with the help of CHCl3 & NaOH.
C6H6 ---> C6H5-CHO
Catalyst - CHCl3 & NaOH
2) Gatterman-Koch reaction -
- In this reaction, benzene is converted to benzaldehyde with the help of CO/HCl & AlCl3/CuCl.
C6H6 ---> C6H5-CHO
Catalyst - CO/HCl & AlCl3/CuCl

Hope this helps...
Explanation:
Answer:
Carbon-14 has a half life of 5730 years. This means it takes 5730 years for half of the carbon-14 atoms to decay to carbon-12 in a given sample (eg: 100 carbon-14, one half life = 50 carbon-14, 50 carbon-12).
Explanation:
Enter a chemical formula to calculate its molar mass and elemental composition: Notice: your ... as a zero '0' Molar mass of Na2Co3*10H2O<span> is 402.9319 g/mol ...</span>
Answer: There are
five <span>bonding pairs of electrons in Methanol.
Explanation: Those electron pairs which are being shared between two atoms in molecule are called as
bonding pair electrons. While, those electron pairs which are not involved in bond formation and are not shared between two atoms are called as
Non-Bonding electron pairs.
In molecule of
Methanol as shown below, it can be seen that carbon atom is forming four bonds with three hydrogen atoms and one oxygen atom by sharing four electron pairs and oxygen is forming two bonds, one with carbon atom and one with hydrogen atom. There are two lone pair of electrons present on oxygen atom which are not taking part in and formation.</span>
<u><em>NOTES TO TAKE DOWN: </em></u>
<em>Apparent brightness is a human measurement, and it would change for each star if the measurement were taken from another location. The more precise counterpart of apparent brightness is called absolute brightness (or absolute magnitude) and is the measure of the luminosity of a star, but on a common scale.</em>
<u><em>ANSWER:</em></u>
<em>Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer.</em>
