Answer:
The correct place to click on any of the double peak showing between 2500 and 3000
on the uploaded question
Explanation:
The group which is being highlighted is an Aldehyde functional group denoted by this structure (
)
This groups stretch on the infrared spectrometer gives two medium intensities peaks
Its stretch comes at 2820 - 2850 peak 1
and at 2720 - 2750 peak 2
So the correct click would be on any of the two peaks between 2500 - 3000 region
Answer: CaCO3 reaction.
Explanation: CaO and combine together to result in the formation of calcium carbonate compound. we know it is a synthesis reaction.so we can conclude that the most likely products of Cao + co2 → CaCO3 reaction.

Answer: B. 0.6125 m
For spherical concave mirror:
Height of the object, 
Height of the image, 
Object distance, u=-0.7 m
we need to find the distance of the image, v.
These are related by the following formula:
Insert the values:
Hence, option B is the correct.
