When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is 96, 485 coulombs (C) and 1 ampere = 1 coulomb/second (C/s). What mass of Cu(s) is electroplated by running 28.5 A of current through a Cu2+ (aq) solution for 4.00 h? Express your answer to three significant figures and include the appropriate units.
How many minutes will it take to electroplate 37.1 g of gold by running 5.00 A of current through a solution of Au+(aq)? Express your answer to three significant figures and include the appropriate units.

0 is the only option that belongs to the set of Whole numbers.

Step-by-step explanation:

We know that whole numbers:

are general counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on.contains natural numbers that start from 1 onwards.contains positive integers along with 0.

In general, the set of whole numbers is:

W = {0, 1, 2, 3, ...}

Thus, the set of whole numbers DOES NOT include negative integers and fractions.

Therefore, 0 is the only option that belongs to the set of Whole numbers.
