A solution whose concentration of solute is equal to the maximum concentration that is predicted from the solute's solubility is called saturated solution.
Solubility can be defined as a terminology that is used to describe how readily a chemical substance or compound can be dissolved in a solvent to form a solution.
In Science, a chemical substance or compound is said to be soluble if it dissolves completely in a solvent while it is insoluble if it doesn't dissolve or only dissolves partially.
In conclusion, a saturated solution refers to a solution whose concentration of solute is equal to the maximum concentration that is predicted from the solute's solubility.

Answer:
These all are example of ionizing radiations.
Explanation:
Alpha beta and gamma radiations are the examples of ionizing radiations. When an atom is an excited state and having high energy, the atom is in unstable state. The excess of energy is released by the atom to get the stability. The released energy is in the form of radiations which may include alpha, beta, gamma, X-ray etc.
Alpha radiations:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic
number 2 less than the starting atom.
Beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
Gamma radiations:
Gamma radiations are high energy radiations having no mass.
Answer:
a
Explanation:
(2) It has a higher concentration of OH– than H3O+ and causes litmus to turn blue.
(3) It has a higher concentration of H3O+ than OH– and causes methyl orange to turn yellow.
(4) It has a higher concentration of OH– than H3O+ and causes methyl orange to turn red.
A solution with a pH of 9 will have a higher concentration of and will turn red litmus to blue.
It is the degree of acidity or alkalinity of substances.
A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline or basic.
A base generally have as the only negative ions when ionized in aqueous solutions. Bases also turn red litmus to blue.
Thus, a solution with a pH of 9 will have a higher concentration of and will turn red litmus to blue.

Answer: Option (2) is the correct answer.
Explanation:
It is known that when pH of a solution is less than 7 then the solution is acidic in nature and turns blue litmus into red. Whereas when pH of a solution is more than 7 then the solution is basic in nature and turns red litmus into blue.
Hydrogen ions can also be released in the form of hydronium ions ().
And, when a solution has pH 9 then it means the solution is basic in nature.
That is, there will be more number of hydroxide or ions as compared to hydrogen ions or ions.
Thus, we can conclude that the statement it has a higher concentration of OH– than H3O+ and causes litmus to turn blue correctly describes a solution with a pH of 9.
14/7N + ____ ---> 14/6C + 1/1H
Explanation:
The given reaction equation is as follows.
+ ___
As there is release of one hydrogen which shows that mass number has increase by 1 on the product side.
Therefore, particle must be added in order to balance the given reaction equation.
Hence, the complete reaction equation will be as follows.
To complete the nuclear reaction equation, the particle required is a neutron (1/0n). It's calculated based on the law of conservation of mass and atomic numbers in nuclear reactions.
To complete the nuclear reaction equation 14/7N + ____ ---> 14/6C + 1/1H, we need to conserve both the mass number (the sum of protons and neutrons) and atomic number (number of protons). On the left side of the equation, we have nitrogen (represented by 14/7N), with a mass number of 14 and atomic number of 7. On the right side, Carbon (14/6C) has atomic number 6 and a mass number of 14 and Hydrogen (1/1H) has atomic number 1 and a mass number of 1. So, to balance the equation we need an element with atomic number (7-6-1) = 0 and mass number (14-14-1) = -1. This element is a neutron (represented as 1/0n), as it has a mass number of 1 and atomic number of 0.

b. tremendous amounts of mass.
c. a series of chemical reactions.
d. particle accelerators.
In nuclear fission, great amounts of energy are produced from very small amounts of mass, as described by Einstein's mass-energy equivalence principle E=mc². The energy is derived from the conversion of a small amount of nuclear mass.
During the process of nuclear fission, large amounts of energy are actually released from very small amounts of mass. This is in accordance with Einstein's mass-energy equivalence principle expressed in his famous equation E=mc², where E represents energy, m is the mass, and c² is the speed of light squared. This equation depicts that even small amounts of mass can produce tremendous energy when speed of light is raised to power of two which is a very large number. Therefore, the correct answer to your question is Option A: very small amounts of mass.
