How many grams of brcl form when 239.7g cl2 react with excess br2

Mass = 1568.9 g

Explanation:

Given data:

Mass of Cl₂ = 239.7 g

Mass of BrCl form = ?

Solution;

Chemical equation;

Cl₂ + Br₂ →  2BrCl

Number of moles of Cl₂:

Number of moles = mass / molar mass

Number of moles = 239.7 g/ 35.5 g/mol

Number of moles =  6.8 mol

Now we will compare the moles of Cl₂ and BrCl.

                          Cl₂      :         BrCl

                            1       :            2

                         6.8      :        2×6.8 mol = 13.6 mol

Mass of BrCl:

Mass = number of moles × molar mass

Mass = 13.6 mol × 115.357 g/mol

Mass = 1568.9 g

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
