<u>Answer:</u> The ion charge formed by Group I will be +1, by Group VI will be -2 and by Group III will be +3.

<u>Explanation:</u>

Ions are formed when electrons are lost or gained by an atom. When an atom looses electrons, it forms a positive ion known as cations and when an atom gains electrons, it forms a negative ion known as anions.

The electronic configuration of the elements present in

  • <u>Group I:</u> ns^1 where n is the number of period

This configuration will loose 1 electron and thus will form an ion of +1.

  • <u>Group VI:</u> ns^2np^4 where n is the number of period

This configuration will gain 2 electrons and thus will form an ion of -2.

  • <u>Group III:</u> ns^2np^1 where n is the number of period

This configuration will loose 3 electrons and thus will form an ion of +3.

Hence, the ion charge formed by Group I will be +1, by Group VI will be -2 and by Group III will be +3.

A sample in the laboratory is found to contain 3.36 grams of hydrogen, 20.00 grams of carbon, and 26.64 grams of oxygen. The mol
KonstantinChe [14]

Answer:

Empirical formula is CH₂O.

Molecular formula = C₆H₁₂O₆

Explanation:

Given data:

Mass of hydrogen = 3.36 g

Mass of carbon = 20.00 g

Mass of oxygen = 26.64 g

Molar mass of compound = 180.156 g/mol

Empirical formula = ?

Molecular formula = ?

Solution:

Empirical formula:

It is the simplest formula gives the ratio of atoms of different elements in small whole number

Number of gram atoms of H = 3.36 / 1.01 = 3.3

Number of gram atoms of O = 26.64 / 16 = 1.7

Number of gram atoms of C = 20 / 12 = 1.7

Atomic ratio:

            C                      :        H            :         O

           1.7/1.7                :     3.3/1.7       :       1.7/1.7

              1                     :           2          :        1

C : H : O = 1 : 2 : 1

Empirical formula is CH₂O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = CH₂O = 12×1 + 2× + 16

Empirical formula mass = 30

n = 180.156 / 30

n = 6

Molecular formula = n (empirical formula)

Molecular formula = 6 (CH₂O)

Molecular formula = C₆H₁₂O₆
