Answer:
19.3 L
Explanation:
V= n × 22.4
where V is volume and n is moles
First, to find the moles of CO2, divide 38.0 by the molecular weight of CO2 which is 44.01
n= m/ MM
n= 38/ 44.01
n= 0.86344012724
V= 0.86344012724 × 22.4
V= 19.3410588502 L
V= 19.3 L
Answer: A) Water Explanation: Water molecules are polar molecules
Answer:
Cohesion
Explanation:
Cohesion tension theory of water movement up the tree vessels
Cohesion is the term used to describe the binding forces present in water molecules through hydrogen bonds as such the water molecules have considerable tensile strenghth allowing them to be pulled up into the leaves of plants through the tree vessels without breakage as longitutudinal stress are placed on the water as it is pulled up
Answer:
A Fridiel craft catalyst will convert benzene to acetophenone.
Permanganate catalyst can be used to convert toluene to acetophenone.
Explanation:
Benzene can be reduced to acetophenone by the addition of anhydrous aluminium chloride, AlCl₃
The mechanism is as follows:
Benzene + Acetyl choloride → acetophenone
To convert toluene to acetophenone, the following steps are necessary:
- Oxidation of Toluene to Benzoic acid.
This is done by refluxing toluene with alkaline potassium permanganate (KMnO₄+ Na₂CO₃).
-
Benzoic acid is converted to Benzoyl chloride by treating with thioyl chloride and heating at about 80 ⁰C.
-
Benzoyl chloride is treated with methyl lithium to form Acetophenone.
Answer:
eight
Explanation:
Hence, from the above given configuration it is clear that the number of valence electrons in the Argon atom is eight.
