Answer:
a unit of measurement equal to 149.6 million kilometers, the mean distance from the center of the earth to the center of the sun.
Explanation:
Answer:
The class of this compound is <u>aldehyde or ketone (i).</u>
Explanation:
Absorption peak at 1720 cm-1 shows the presence of a carbonyl group, possibly an aldehyde or ketone with C=O bond.
Further information on molecular formula would be required for structural elucidation.
Answer: Option (c) is the correct answer.
Explanation:
Polar molecules are defined as the molecules that chemically combine together and have partial opposite charges.
For example,
is a polar molecule as due to the difference in electronegativity of hydrogen and oxygen atom there is partial positive charge on hydrogen atom and partial negative charge on oxygen atom.
On the other hand, molecules which are neutral in nature are known as non-polar molecules. A non-polar molecule is formed by equal sharing of electrons.
For example,
is a non-polar molecule.
As in a large polar molecule, there will be greater force of attraction between the oppositely charged ions due to large surface area. Hence, large amount of heat needs to given in order to break the bonds.
Therefore, we can conclude that a large polar molecule will have the highest boiling point.
Yes, it is a Compound.
They both comprehend with the atoms of each sourse!
Answer:
Nichrome
Answer: Hot water system coils are commonly made up of metal alloys which are a combination of two or more elements. The most commonly used metal alloy is “Nichrome”. Nichrome is an alloy of nickel (80%) and chromium (20%).
