I am taking the same test! ;)

1. RbF --> Rubidium Fluoride

Change fluorine to fluoride

2. CuO --> Copper (II) Oxide

Change oxygen to oxide. Oxide has a charge of -2. Since no subscripts are written, it means they have the same opposite charge. So, we use Copper (II).

3. (NH₄)₂C₂O₄ --> Ammonium Oxalate

NH₄ is ammonia, but we change it to ammonium for poly atomic ions. 

I hope this helps!

aleksklad [387]

Answer:

Distance: 16m Displacement: 8m North

Explanation:

Total distance is the total amount traveled, regardless of direction. So, you would just add 12 and 4 to get a total distance of 16m. Displacement is the distance/direction from the start to the end point, regardless of which way you got there. So, to find displacement, you just subtract:

12m North - 4m South = 8m North

** I could be wrong so definitely double check this answer with a similar question**
