Which of the following does ((not)) describe a single-displacement reaction?

a. occurs when one element replaces another element in a compound.

b. ab+c > ac+b

c. occurs when a substance is broken down into two or more simpler substances.

d. also called a redox reaction

The correct answer is option C.

Explanation:

Single replacement reaction : It is a type of chemical reaction in which element exchange their position with the position of another element in its compound molecule.

It is also called redox reaction because one element getting oxidized and another one getting reduced.

Hence, the correct answer is option C.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
