Answer:
The answer is b, c, d, e
Explanation:
b. 2 N2O5 → 4 NO2 + O2
r = k [N2O5]^2 --> Second-order regarding global reaction
c. 2 HI → H2 + I2
r = k [HI]^2 --> Second-order regarding global reaction
d. 2 N2O → 2 N2 + O2
r = k [N2O]^2 --> Second-order regarding global reaction
e. 2 NO2 → 2 NO + O2
r = k [NO2]^2 --> Second-order regarding global reaction
150/30 = 5
HF1 20/2 = 10
HF2 10/2 = 5
HF3 5/2 = 2.5
HF4 2.5/2 = 1.25
HF5 1.25/2 = 0.625
Answer: 0.63g
57.0 is it rounded to three sig figs. You count three spaces then round from there, which would be the zero and you would round down because the four is there.
