Carbon Dioxide from the air is used to make sugars during the Photosynthesis.
The Photosynthesis is a process in which green plants uses the sunlight to create dioxygen and their food.
The formula of the dioxygen is: 6HO2 + 6CO2 --> C6H12O6 + 6O2
We can clearly see the formation of Glucose, a kind of sugar, from his presence in the product part: C6H12O6
Hope this Helps! :)
Answer
Option D
When a grignard Reagent reacts with Ethylene Oxide... A Primary Alcohol is Formed.
CH2OCH2 + RMgX ==> RCH2CH2OMgX
When You Hydrolyze
You have
RCH2CH2OH
The Text written below may come in handy someday.
Hope you find it helpful.
One of the preparation of Alcohols is via Reaction with "Grignard Reagents" .
Grignard Reagents have the formula "RMgX"
Where R is an alkyl group eg CH₃, C₂H₅ etc
X is a halogen eg Cl,Br etc
Ethylmagnesiumbromide fits the description of grignard Reagent from what I wrote above.
The formula for Ethylmagnesiumbromide is
"C₂H₅MgBr"
Now
When grignard reagents react with Alkanals... They form alcohols.
Note this trend.
When a grignard reagent reacts with Methanal(Formaldehyde)... It forms a Primary Alcohol.
When a grignard reagent reacts with any other Alkanal besides Methanal(formaldehyde) ... it forms Secondary Alcohols.
Explanation:
The prefix trans- and its variant tra- mean "across".
A translucent substance allows some light to go "across" it to the other side. Also, think about a transparent substance: it allows light to go "across" it; or a translation, it is a going "across" from one language into another.
Explanation:
from definition of density we have
density=mass/volume
and density=55 mass=220g
volume=220/55
volume=4ml
or 4×10^-3l
Answer:
The concentration of the copper(II) sulfate solution is 0.99 M
Explanation:
Step 1: Data given
Mass of copper(II) sulfate = 79 grams
Volume of the flask = 500 mL
Molar mass copper(II) sulfate = 159.61 g/mol
Step 2: Calculate moles copper(II) sulfate
Moles CuSO4 = Mass CuSO4 / molar mass CuSO4
Moles CuSO4 = 79.0 grams / 159.61 g/mol
Moles CuSO4 = 0.495 moles
Step 3: Calculate concentration
Concentration CuSO4 = moles / volume
Concentration CuSO4 = 0.495 moles / 0.5 L
Concentration = 0.99 M
The concentration of the copper(II) sulfate solution is 0.99 M
