Sort the following chemicals for their ability to act as an oxidizer. List from strongest to weakest; 1 being strongest, 6 being
2 answers:
Explanation:
A oxidizing agent or oxidizer is a substance that loses electrons and itself gets reduced.
Also, a substance or element that has more positive value of or reduction potential will act as a strong oxidizer because it will easily get reduced.
Therefore, standard reduction potential of the given elements is as follows.
K = -2.92
Ag = 1.83
Au = 0.80
Cu = 0.16
Ni = -0.23
Ca = -2.76
Hence, Ag has the highest positive value and calcium has the lowest. Thus, list from strongest to weakest oxidizer are as follows.
Ag > Au > Cu > Ni > Ca > K

Answer: compound
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air
