Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar c

Sati [7]

An ionic bond is formed by the transfer of electrons from one atom to the other. It is usually formed between a metal + non-metal.

A covalent bond is formed by sharing of electrons between two atoms. It is formed between two nonmetals. A polar covalent bond is formed between 2 non-metals which differ in their electronegativities. In contrast, in a non-polar covalent interaction the two atoms could either be the same or have very close electronegativities.

1) P and I : Both non-metals with different electronegativities= Polar Covalent

2) Fe and O: Metal + non-metal = Ionic

3) S and Cl: Both non-metals with different electronegativities= Polar Covalent

4) S and S: Both non-metals and the same atoms = Non-polar Covalent

5) Br and Br: Both non-metals and the same atoms = Non-polar Covalent

6) O and Cl: Both non-metals with different electronegativities= Polar Covalent

7) Be and Cl: Metal + non-metal = Ionic

8) Al and N: Metal + non-metal = Ionic

The empirical formula of pyrogallol is C2H2O. Its molar mass is 126 g mol-1. What is the molecular formula?C4H4O2C2H6O3C6H6O3C2H

VARVARA [1.3K]

Answer:

The molecular formula of pyrogallol is: C6H6O3

Explanation:

Step 1: Data given

Empirical formula of pyrogallol is C2H2O

Molar mass of pyrogallol = 126 g/mol

Molar mass of Carbon (C) = 12 g/mol

Molar mass of hydrogen (H) = 1.01 g/mol

Molar mass of oxygen (O) = 16 g/mol

Step 2: Calculate molar mass of the empirical formula

2*12 + 2*1+ 16 = 42 g/mol

Step 3: Calculate the molecular formula

To find the molecular formule , we should multiply the empirical formula by n

n can be found by dividing molar mass of pyrogallol by the molar mass of the empirical formula

n = 126 g/mol / 42 g/mol ≈ 3

We should mulitply the empirica lformula by 3

3*(C2H2O) gives C6H6O3

if we calculate the molar mass now:

6*12 +6*1 + 3*16 = 126 g/mol

The molecular formula of pyrogallol is: C6H6O3
