The answer is five! Don't tell me how I got that because my sister did the problem 2 minutes ago because I told her this question! Hope this help!
Answer:
A
Step-by-step explanation:
A is a triangular prism
A4 means the 4th number
so it is 17
(-2,0) (0,6) (1,0) this should be it
The first reaction represented is a decomposition reaction due to the fact the bonded pair are being split apart.
The second equation is a single displacement because the B and C have switched places, which is the only change making it a single displacement. If there had been another bond and A had also moved, it would be double.
