Question

question 11 (1 point)
write the name of each chemical formula
gaf₃

question 12 (1 point)
write the name of each chemical formula
cds

Explanation:

For \(GaF_3\):

• \(Ga\) is the chemical symbol for gallium.
• \(F\) is the chemical symbol for fluorine.
• In naming ionic compounds, the metal (gallium) is named first, followed by the non - metal (fluorine). The ending of the non - metal is changed to -ide. So, \(GaF_3\) is gallium fluoride.

For \(CdS\):

• \(Cd\) is the chemical symbol for cadmium.
• \(S\) is the chemical symbol for sulfur.
• Using the rules for naming ionic compounds (metal first, non - metal with -ide ending), \(CdS\) is cadmium sulfide.

Answer:

Question 11: gallium fluoride
Question 12: cadmium sulfide
