To make a solution of lemonade, lemon juice and sugar are dissolved in water. the water is the <u>Solvent </u>in this example.
Solvent Examples. Common examples of solvents consist of water, ethanol, methanol, and acetone. The term 'solvent' may be defined as a substance that has the ability to dissolve a given solute to form a solution with it.
Solvents are substances that are used to dissolve the solutes used in the formulation. These solutes can be solids, liquids, or gaseous in nature. Thus solvents are used to get a solution upon interacting the solute with a suitable solvent.
Solvents are usually, however not usually, liquids. They can also be gases or solids. The material dissolved in the solvent is referred to as the solute. collectively, the solvent and solute comprise the solution.

Answer: The Earth is an oblate spheroid which is more elongated along the equator.
Regions along the equator receives more amount of direct sunlight from the sun causing higher temperatures along the region. While places along the poles receives less amount of heat since heat is scattered in a larger area due to the shape of the Earth around the poles.
Explanation: So places along the equator experiences higher temperature due to the direct hit of sunlight. And places along the polar regions experiences cooler temperature since it receives less amount of sunlight.
Answer: The mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For a neutral atom:
Atomic number = Number of electrons = Number of proton
Atomic number= Number of protons = 8
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Given: Number of neutrons = 9
Thus mass number = Number of protons + Number of neutrons = 8 + 9 = 17.
Isotopes are elements which have same atomic number but different mass number.
Thus the mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.

Valence Shell Electron Pair Repulsion (VSEPR) theory Electron pairs around a central atom arrange themselves so that they can be as far apart as possible from each other. ... The repulsion between negatively charged electron pairs in bonds or as lone pairs causes them to spread apart as much as possible.
