Answer:
D
Explanation:
Drilling through the earth to reach areas hot enough to create steam is difficult because the drill can break down deu to hardness of the rocks
Answer:
90.3 L
Explanation:
Given data:
Volume of water produced = 77.4 L
Volume of oxygen required = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
It is known that,
1 mole = 22.414 L
There are 7 moles of oxygen = 7×22.414 = 156.9 L
There are 6 moles of water = 6×22.414 = 134.5 L
Now we will compare:
H₂O : O₂
134.5 : 156.9
77.4 : 156.9/134.5×77.4 =90.3 L
So for the production of 77.4 L water 90.3 L oxygen is required.
Answer:
Benzoyl Chloride
Explanation:
Friedel-Craft Acylation is reaction utilized to add electrophiles (particularly carbonyl group) across double bonds of aromatic compounds.
In given case benzophenone is synthesized using benzene and benzoyl chloride.
Mechanism:
Step 1: In first step benzoyl chloride is treated with lewis acid to generate an electrophile i.e. oxo(phenyl)methylium.
Step 2: In the second step benzene undergoes electrophilic substitution reaction and adds the electrophile.
Step 3: In last step the aromaticity of benzene is restored with the elimination of proton.
Answer:
The Aluminium electron configuration will be 1s^22s^22p^63s^23p^1. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
