Answer: Option (C) is the correct answer.
Explanation:
When two nuclei and a subatomic particle like proton, neutron or high energy electron collide with each other then it results in the formation of two or more different nuclides.
For example,
Whereas in an electrochemical, thermochemical and chemical reaction there occurs change in number of electrons and not in number of protons or neutrons.
Thus, we can conclude that a change in the number of protons or neutrons occurs in nuclear reaction type of reaction.
A change in the number of protons or neutrons occurs inwhich type of reaction? A change in the number of protons or neutrons occurs innuclear reaction. The answer is letter C. The rest of the choices do not answerthe question above.
Answer & explanation:
For an atom to be electrically neutral, it must have the same amount of protons and electrons, but this does not always happen, so compounds called ions arise.
Ions are formed when an atom of an element has electron gain or loss due to reactions. They can be classified into cations and anions.
Anions are atoms that receive electrons, so they are negatively charged.
Examples: Cl⁻, O⁻², N⁻³
Cations are atoms that lose electrons and thus become positively charged.
Examples: Na⁺, Al⁺³, Pb⁺⁴
In addition, some compounds are formed in bonds between negative and positive ions. These are called ionic bonds.
Example: Formation of sodium chloride (table salt).
Na⁺ + Cl⁻ → NaCl
Answer:
Explanation:
Formic acid (HCOOH) is a weak electrolyte when dissolved in water. In an aqueous solution of formic acid, it partially ionizes into its constituent ions. The solutes present in this solution are the ions produced during ionization.
The chemical equation for the ionization of formic acid (HCOOH) in water is as follows:
HCOOH (aq) ⇌ H⁺ (aq) + HCOO⁻ (aq)
In this equation:
HCOOH represents formic acid molecules.
H⁺ represents the hydrogen ions (protons) that are formed when a molecule of formic acid loses a hydrogen ion (H⁺).
HCOO⁻ represents the formate ion, which is the conjugate base formed when a molecule of formic acid donates a hydrogen ion (H⁺).
Since formic acid only partially ionizes in water, not all molecules of formic acid dissociate into ions. This is why it is considered a weak electrolyte.
In living things, enzymes serve as a catalyst.
A material known as a catalyst would be an element or just a compound that quickens chemical reactions. The procedure of catalysis involves introducing a catalyst to a chemical reaction to speed up the process. The reaction does not consume catalysts, and they are unaffected after it.
Proteins called enzymes serve as biological catalysts. Chemical reactions are accelerated by catalysts. Numerous biological processes, including development, blood clotting, disease treatment, respiration, digestion, reproduction, as well as many more, are aided by enzymes.
Proteins are called enzymes to catalyze chemical reactions in our bodies. By reducing the activation energy, they serve as a catalyst to quicken the process. The enzyme has been referred to as a biocatalyst since it speeds up a chemical reaction again without altering its equilibrium.
Therefore, In living things, enzymes serve as a catalyst.
Hence, the correct answer will be option (B)
