What is the basic unit of chemistry

The atom

How is electroplating done

the metal on which electroplating is to be done is taken as cathode ( negative electrode) . the metal of which electroplating is to be done is taken as anode ( positive electrode) and the salt solution of the metal of which electroplating is to be done is taken as electrolyte .

example-

if we want to electroplate iron with copper then iron is taken as cathode and copper is taken as anode and electrolyte is copper sulphate.Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes. This is done through the use of copper in a copper sulfate bath.

How is stoichiometry used

Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.

What occurs at the cathode of a galvanic cell

The reduction half-reaction of a redox reaction

How do periodic trends illustrate stability and change in chemistry

Periodic trends illustrate how some elements are very reactive while others are stable.

What is the voltage of an electrolytic cell with nickel and copper electrodes

-0.59 V

What will form a spontaneous redox reaction between two elements

The element with the greater reduction potential is the one that is reduced.

What drives a galvanic cell

A Spontaneous Redox Reaction

What is the overall voltage for a redox reaction with the half reactions Ag e Ag and Cu2 2e

0.80-0.34

What would be the percent yield of the reaction be if the theoretical yield is 11.22 g but the actual yield was 8.67 g

In this case the yield is 77,27 %.

What power source contains a chemical that releases electrons on one side and a chemical that accepts the electrons on the other side.

A Battery

In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made

The amount of Koh

which equation is balance in a basic solution

CIO H2O 2e- CI- 2OH
