Q.1 Define Molecular formula, Empirical formula, structural formula.

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs.

Q.2 Write the molecular formula of the following;

Potassium hydroxide - KOH

Magnesium chloride - MgCl_2

Sulphur Dioxide - SO_2

Potassium dichromate - K_2Cr_2O_7

Plaster of Paris - Ca_2H_2O_9S_2

Baking soda - NaHCO_3

Hope it's helpful to you

Answer:

Definition of molecular formula:

A molecular formula consists of a chemical symbols for the constituents element followed by numeric subscripts describing the number of atoms of each elements present in the molecule is called molecular formula.

Define Empirical formula:

A formula that gives the simplest whole number ratio of the different atoms in a compound.

Define Structural formula:

Structure formula is a form of the molecular formula that indicates the arrengment of atoms within a molecules by connecting atoms with a line is called structural formula.

Molecular formulas:

1) Potassium hydroxide = KOH

2) Magnesium chloride = MgCl2

3) Sulphur dioxide = SO2

4)Potassium dichromate = K2Cr207

5) plaster of Paris = Ca2h2O9S2

6) Baking soda = NaHCO3.
