Answer:
2m/s^2
Explanation:
Fnet = F2-F1
ma = 8-4
2a = 4
Dividing both sides by 2
a = 2
Therefore (a) thus acceleration is 2m/s^2
The correct answer is species
Answer:
2.77g of
can be produced.
Explanation:
Use stoichiometry.
Balanced equation:
⇒ 

3 : 1 **
0.0623** :
= 0.0623


m= (0.020767)(133.34)
m= 2.77g
