Answer: Option (d) is the correct answer.
Explanation:
It is known that length of a bond is inversely proportional to the bond strength. This also means that a single bond has long length due to which it is weak in nature.
And, a double bond is shorter in length and has more strength as compared to a single bond. Whereas a triple bond has the smallest length and it has high strength as compared to a double or single bond.
For example, carbon monoxide is CO where there is a triple bond between the carbon and oxygen atom.
Carbon dioxide is where there exists a double bond between the carbon and oxygen atom.
A carbonate ion is when two oxygen atoms are attached through single bond with the carbon atom and another oxygen atom is attached through a double bond to the carbon atom.
Hence, we can conclude that order of increasing bond strength of the given carbon oxygen bond is as follows.
Carbonate ion < carbon dioxide < carbon monoxide
Answer:
New volume = 150 mL
Explanation:
Initial temperature, T₁ = 35°C
Initial volume, V₁ = 350 mL
We need to find the change in volume when the temperature drops to 15°C.
The relation between the temperature and the volume is given by Charle's law. Let new volume is V₂. It can be given by :
So, the new volume is 150 mL.
