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.
32, you are adding 4 to each number
Answer:
y would be 14
Step-by-step explanation:
If y=4 and x=12, that means x is 3 times the amount of y. Therefore, if x is 42, y should be three times less the amount. 42/3 is 14 and that's your correct answer!
