Chemistry

The atom

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.

The average atomic mass represents the weighted average of the masses of the isotopes of the element.

16.0 lbs = 7,257 g of O2

Oxygen exists in the gas form as 02

7,257g O2 * 1 mol O2/ 32 g * 2 mol O / 1 mol O2 * 6.022x10^23 atoms/mol

= 2.73E26 atoms of O

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

There are relatively few atoms, but they make many molecules.

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