Answer: its a single replacement reaction
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
<h3>What is a synthesis reaction?</h3>
A synthesis, or combination reaction, is a kind of reaction in which two substances combine to form a bigger molecule.
The generic reaction is:
a + b = c
Some common synthesis reactions are:
- Two elements combine to form a compound.
Fe + S = FeS
- One element and one compound combine to form a compound.
O₂ + 2 SO₂ = 2 SO₃
- Two compounds combine to form another compound.
CaO + CO₂ = CaCO₃
In all the examples above, we can verify that the substances (elements or compounds) combine with each other to form another substance (product).
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.

Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.
Quantitative data is defined as the data that can be counts in number or can be measured in numbers. There are two main types of quantitative data : discreate data and the continuous data. examples are age , date, distance , weight etc. so, the countable and measurable quantities in numbers is quantitative data. Wavelength here is measured in numbers . so, wavelength is the quantitative data.
Thus, Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.

Correct answer: <span>An isomer with a branched structure will require:
less energy to melt than the straight chain structure.
Reason:
</span>
The branched chain compounds have lower melting and boiling points as compared to straight chain isomers.This is due to the fact that branching makes the molecule more compact. This results in decreases in surface area of isomer. But, the intermolecular attractive forces depends on the surface area of compound. Thus, branched isomers have lower intermolecular force of interaction, as compared to straight chain isomers. Consequently, the melting/boiling points of the branched chain isomers are lower as compared to straight chain isomers.
