7.49 x 105 mm<br> 34500 inches<br> 0.45 miles<br> 885 yards<br> smallest to largest lengths
emmasim [6.3K]
30.962
34500
28512
31860

answer:

7.49 x 105 mm
0.45 miles
885 yards
34500 inches

reason:

I converted all the measurements to inches.
First, I multiplied 7.49x105 to get 786.45mm
Then, I divided it by 25.4 to get about 30.92 inches

Next, I converted 0.45 miles to inches by multiplying it by 63,360 to get 28,512 inches

For the yards, I took 885 and multiplied it by 36 to get 31,860 inches

Since the last one was already in inches, all I needed to do was put them in order from least to greatest

The following data are obtained for the decomposition of N2O5 at a certain temperature: 2N2O5(g) ↔ 4NO2(g) + O2(g) Time(s) 0 200
cricket20 [7]

Answer:

K = 0.0003 s⁻¹

Explanation:

The reaction is

2N₂O₅ = 4NO₂ + O₂

The equilibrium is

K[N_{2} O_{5} ]=-\frac{1}{2} \frac{d[N_{2} O_{5} ]}{dt} \\\int\limits^y_x {d[N_{2} O_{5} ]}{} \, =-2k\int\limits^t_0 {dt} \,\\ln[N_{2} O_{5} ]=-2kt+ln[N_{2} O_{5} ]

a plot is attached

From the plot, the slope is -0.0006

-2 * K = -0.0006

K = 0.0003 s⁻¹
