Answer : The correct option is (A) Salt.
Explanation :
Solute : It is defined as a substance which is dissolved in a solvent. It is a smaller component of a solution.
Solvent : It is defined as a substance that dissolves a solute. It is a larger component of a solution.
In a salt and water solution, the solute is salt component and the solvent is water component.
Therefore, the correct answer is Salt.
A base turns blue litmus red.
A base turns orange litmus red.
A base turns yellow litmus blue.
Answer;
A base turns red litmus blue.
Explanation;
Litmus paper is an acid/base indicator that changes color to identify bases and acids.
Red litmus paper is used in chemical laboratories to identify bases. A base is a substance that accepts hydrogen ions (H+) in water. The color of a red litmus paper remains the same under acidic conditions and turns blue under basic conditions.
Blue litmus paper turns red under acidic conditions and remains the same under basic conditions. An acid is a substance that releases hydrogen ions in an aqueous solution. Blue litmus paper is prepared by treating plain paper with lichen-blue litmus. Blue litmus paper is typically used to test acids, such as sulphuric acid, hydrochloric acid, nitric acid, ethanoic acid, citric acid, and vinegar.

Answer:
Thermohaline Circulation
Explanation:
The process is known as “Thermohaline Circulation”. In the Earth’s polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
b) compound
c) isotope
d) proton
e) molecule
Answer:
A
Explanation:
An element is a substance that cannot be broken down into simpler substances using ordinary chemical procedures. To disintegrate an element, procedures like nuclear reactions needed to be used.
In fact, it was thought of that the elements are indivisible during the days of Dalton, but advances in science and technology has shown that these elements could be broken down albeit not easily
An element is a substance that cannot be broken down into other substances by ordinary chemical methods. It is the basic unit of all matter. Examples of elements include gold, silver, and carbon.
A substance that cannot be broken down into other substances by ordinary chemical methods is called an element. This is because elements are the fundamental materials of which all matter is composed. For instance, gold, silver, and carbon are examples of elements. Unlike compounds, isotopes or molecules, an element is made up of the same type of atom and cannot be decomposed into simpler substances by any ordinary chemical processes.
