Answer is: B. Decomposition.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

Electrolysis of water is the decomposition reaction, because from one molecule (water) two molecules (hydrogen and oxygen) are produced.

Water is separeted into two molecules:

Reaction of reduction at cathode: 2H⁺(aq) + 2e⁻ → H₂(g).

Reaction of oxidation at anode: 2H₂O(l) → O₂(g) + 4H⁺(aq) + 4e⁻.

Answer:

The answer to your question is below

Explanation:

Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.

Kind of elements Difference of electronegativity Bond

a) MgO Metal - Nonmetal 3.44 - 1.31 = 2.13 Ionic

b) SrCl₂ Metal -Nonmetal 3.16 - 0.95 = 2.21 Ionic

c) O₃ Nonmetal- Nonmetal 3.44 - 3.44 = 0 Covalent

d) CH₄O Nonmetal-Nonmetal 3.44 - 2.55 = 0.89 Covalent

Carbon, Hydrogen and oxygen are nonmetals

2) Silver coins can conduct electricity.

Triss [41]

The answer is D. Stars are formed from interstellar clouds because of the Law of Universal Gravitation. The interstellar clouds are termed as nebula. When other stars dies a supernova occurs then the gravity from this pushes matter into the clouds until it cannot overcome the gravitational pull and it collapses which heats matter up forming a star.
