What are the bonding states for the following materials? 1. Brass 2. Rubber 3. BaS 4. Solid xenon
MaRussiya [10]

Answer:

A chemical bond is defined as the force which helps to bind more than two atoms in a molecule. There are different types of chemical bonding are present in molecules such as:

1) Ionic bonding: Because of the transfer of electrons it is present in ionic compounds. BaS is an example of ionic bonding which is containing some covalent character.

2) Covenant bonding: Because of the sharing of electrons it forms molecules. Rubber is the example of covalent bonding with some van der walls.

3) Metallic bonding: In the free state it is present in atoms of metal such as Brass is a good example of a metallic bonding because it is a metal alloy.

4) Van der walls bonding: In atoms, It includes repulsion and attraction. Solid xenon is the example of Van der wall bonding because it is an inert gas.

First we need to calculate the number of moles of FeS_{2}:

number of moles = mass (grams) / molecular mass (g/mol)

number of moles of FeS_{2} = 198.2/120 = 1.65 moles

From the chemical reaction we deduce that:

if            4 moles of FeS_{2} produces 8 moles of SO_{2}

then  1.65 moles of FeS_{2} produces X moles of SO_{2}

X = (1.65×8)/4 = 3.3 moles of SO_{2}

Now we can calculate the mass of SO_{2}:

mass (grams) = number of moles × molecular mass (grams/mole)

mass of SO_{2} = 3.3×64 = 211.2 g
