B) CBr₂H₂

C) GeI₄  

D) AsO₃  

E) CF₄

F) PO₃

G) H₂S₂

Lewis Structure for each= ?

Solution:

To draw the Lewis Structure

•Put the one atom in the center and draw the other on the outside around the center atom

•Then draw the 2, 2 valence electrons between atoms that form chemical bond

•So we will draw total electrons contributed in the structure

•then we count electrons around each atom of the compound that it have 8 or 2 electrons to complete its octet or duplet respectively

Lewis Structure of all the asked compounds are in attachment

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
