The longest hydrocarbon chain in the given compound is hexane, therefore it is the parent chain to be considered with one methyl group attached to the 3rd carbon and one chloro attached on the 2nd carbon, therefore the name of the compound is 2-chloro-3-methylhexane

Answer:
A) Melting
Explanation:
The three changes of phase described in this problem are:
- Melting: melting occurs when a substance in solid state turns into liquid state. Since molecules in liquid state have more energy than molecules in solid state (because in liquids, molecules can slide past each other, while in solids they can't move, but only vibrate), thermal energy must be added in order to melt a substance
- Freezing: freezing occurs when a liquid substance turns into solid state (the opposite of melting). Since molecules in liquid state have more energy than molecules in solid state, thermal energy must be removed from the substance in order to cause freezing
- Condensation: condensation occurs when a gaseous substance turns into liquid state. Since molecules in gaseous state have more energy than molecules in liquid state, thermal energy must be removed from the substance in order to cause condensation
So the correct option is
A) melting
Climate is the answer because a meteorologist study climate
1) A. the have different protons.
The number of protons is the atomic number and this is how the products are ordered in the periodic table. Every element has different atomic number.
2) A. 8 p, 8 e and 8 n
The atomic number of O is 8, which means it has 8 protons. The number of protons must equal the number of electrons.
3) C. atoms bond with one another in a molecule.
That is what a molecule is: a group ot atoms bonded.
4) D. the bond results from the attractive forces of two opposite charges.
Ionic bonds are formed between ions, a positive ion (cation) and a negative ion (anion).
5) A. the physical and chemical properties of HCl are different from those of H2 and Cl2
You can check physical properties (density for example) and chemical properties (how they react with other elements) in some tables o textbooks.
