Your toothpaste probably contains around 62g of fluorine per tube. How many miles are in one tube?

3.26mole

Explanation:

Given parameters:

Mass of fluorine  = 62g

Unknown:

Number of moles in one tube  = ?

Solution:

A mole is the amount of substance that contains the avogadro's number of particles.

We can find the number of moles of a substance by;

                  Number of moles  =

            Molar mass of Fluorine  = 19g/mol

Substitute in the equation:

           Number of moles  =   = 3.26mole

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
