The classification of the alcohols gives;
- Compound 1 - Primary alcohol
- Compound 2 - Tertiary alcohol
- Compound 3 - Secondary alcohol
- Compound 4 - Secondary alcohol
<h3>What are alcohols?</h3>
Organic compounds occurs in families. The family of compounds is called a homologous series. The homologous series always have a functional group. The functional group is the atom, group of atoms or bond that is responsible for the chemical reactivity of the members of a given homologous series.
Now we know that the alcohols are those organic compounds that contains the -OH group. The could be aliphatic or alicyclic compounds. We shall now proceed to name the kind of alcohols that each of the compounds shown are;
- Compound 1 - Primary alcohol
- Compound 2 - Tertiary alcohol
- Compound 3 - Secondary alcohol
- Compound 4 - Secondary alcohol

Answer:
The correct answer is sedimentary rock.
Explanation:
The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.

Answer:
107,200J or 25.62 kcal
Explanation:
The latent heat of water is 4.2J/g °C so the energy needed to increase the tempearture from 80 °C to 100°C will be:
40g * 4.2J/g °C * (100-80°C )= 3,360J
The heat of vaporization of water is 2260J/g so the energy need to change water from liquid to gas is:
40g * 2260J/g = 90,400J
The heat needed to increase steam temperature should be same as latent heat of water, 4.2J/g °C . So, the energy needed to increase temeprature from 100 to 180 will be:
40g * 4.2J/g °C * (180-100°C )= 13,440J
The total energy needed will be: 3,360J + 90,400J +13,440J= 107,200J
Answer:
Water will generally require more energy for a phase change compared to a similar substance without hydrogen bonds.
