Cubic metre is the metric unit for measuring volume. The cubic centimetre has a particular nomenclature called a millilitre.
The 3-dimensional space that is occupied by matter or surrounded by a surface is measured in volume, which is expressed in cubic units. A derived unit called the cubic metre serves as the SI unit of volume.
A unique designation for the cubic decimeter is the litre. To reduce the chance of confusion between the lowercase letter "ell" (l) and the number one (1), the symbol for the litre is an uppercase letter "ell". The litre cannot be represented by the script letter l (l).

b. silicon-32
c. silicon-46
d. silicon-153
The correct answer is option a, silicon-14
Number of electrons = 14
Number of protons = 14
Number of neutrons = 18
Since atomic number is equal to the number of protons, the atomic number of this specific silicon isotope is 14.
Also, mass number is equal to number of protons and number of neutrons. So mass number so this specific silicon isotope is 14 + 18 = 32
The name of this specific silicon isotope is silicon-14.
Silicon-14 is represented as ³²Si₁₄
B. atom
C. element
D. mineral
A: Scientists have not yet gotten a fusion reaction to happen on Earth.
B: Per gram of fuel, fission releases more energy than fusion.
C: The energy from fusion cannot yet be converted to electricity.
D: Fusion requires conditions that use too much energy to maintain.
According to the nuclear fission and nuclear fusion reactions,energy from fusion cannot yet be converted to electricity.
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Answer:
The correct answer is option c) water and salts
Explanation:
Organic compounds contain carbon and hydrogen bonds. Both nucleic acids and proteins contain these. Water (H2O) and salts (Ex:NaCl) do not.
The pair of compounds that can be classified as inorganic from the given options are water and salts. These lack a carbon-hydrogen bond, unlike nucleic acids and proteins, which are organic.
The pair of compounds that can be classified as inorganic are water and salts. Inorganic compounds are defined as compounds that do not contain a carbon-hydrogen bond, which makes them different from organic compounds. Both water (H2O) and salts, like table salt (NaCl), do not contain any carbon-hydrogen bonds, so they are considered inorganic compounds. On the other hand, nucleic acids and proteins are both complex structures that include carbon-hydrogen bonds, making them organic compounds.
