To determine what the molecular formula is simply find the molar mass of the empirical formula, which is about 13 g/mol and take the value of 26 and divide it by 13. This would give a value of 2.

Use this value and multiply the empirical formula atoms to obtain the new molecular formula.

You can always verify if it is the correct formula by finding the molar mass of the molecular formula and checking to see if it equals 26 g/mol.

C2H2

To solve this problem, first find the empirical formula mass. Since the empirical formula is CH, the empirical formula mass is C (12 g/mol) + H (1 g/mol) or 13 g/mol.

Then, compare this mass to the molar mass to determine the molecular formula.

So, the molecular formula equals 2 times the empirical formula. The molecular formula is C2H2.

The balance chemical equation is follow,

                    2 I⁻  + SO₄²⁻  +  4 H⁺    →    I₂  +  SO₂  +  2 H₂O

According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.

Result:
          So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.

List 2 extensive properties and 3 intensive properties of a 5.0g, 1 cm3 cube of silver
jeka57 [31]

Properties of matter can be broadly classified into two categories:

Physical properties which usually involve a change in the state of matter and Chemical properties which involve a change in the chemical composition of matter.

Now, physical properties can be further classified as:

Extensive: these depend on the amount of the substance, eg: mass, volume  

Intensive: these do not depend on the amount of the substance eg: density, color, melting point, boiling point

Here we are given a 5.0 g and 1 cm3 silver cube :

Therefore:

Extensive properties are-

1) Mass of silver = 5.0 g

2) Volume of silver = 1 cm3

Intensive properties are:

1) Density of silver = mass/volume = 5.0 g/ 1 cm3 = 5.0 g/cm3

2) Melting point of silver = 962 C

3) Color = white/gray
