Draw the Lewis structure for the molecule Carbon Dioxide, Co, and predict the molecular geometry.

Blababa [14]

Answer:

Lewis Structure:

Explanation:

CO2 Lewis Structure

So CO2 = 4 + 6(2) = 16. So, total valence electrons are 16. Carbon is the least electronegative that means it stays at the center. So, put the Carbon in the middle and then set the oxygen either side of that.

In this experiment you are directed to add a limited amount of NaOH (aq) and then an excess amount. A similar strategy will be u

Verizon [17]

The reason for adding a limited amount and then an excess amount is that initially a metal hydroxide may form which becomes soluble when more base is added and the metal complex forms.

In qualitative analysis is a common to add the base in drops and then in excess. When added in drops, the metal hydroxide is formed. This metal hydroxide is often insoluble.

After this metal hydroxide is formed, the base could be added in excess such that the metal hydroxide dissolves in the excess base by forming a complex.

For instance;

CuCl2(aq) + 2NaOH(aq) -------> Cu(OH)2(s) + 2NaCl(aq)

Cu(OH)2(s) + 2OH^-(aq) -------> [Cu(OH)4]^2+(aq)
