Chemistry

A liquid with something dissolved in it

The molecular formula specifies the actual number of atoms of each element in a molecule.

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.

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

A+B ➝AB

it loses mass

62

-2.37 - 0.34

Putting different ideas together

In this case the yield is 77,27 %.
