The table shows the concentration of a reactant in the reaction mixture over a period of time.
saveliy_v [14]
<h3>Option C</h3><h3>The average rate of the reaction over the entire course of the reaction is: 2.0 \times 10^{-3}</h3>

<em><u>Solution:</u></em>

Average rate is the ratio of concentration change to the time taken for the change

Average\ rate = \frac{ \triangle c }{\triangle t }

The concentration of the reactants changes 1.8 M to 0.6 M

here, the time interval given is 0 to 580 sec

Therefore,

Average\ rate = \frac{1.8-0.6}{580} \\\\Average\ rate = \frac{1.2}{580} \\\\Average\ rate \approx 2.0 \times 10^{-3}

Thus option C is correct

If two angles are supplementary and one angle measures 47°, what is the measure of the other angle? 43° 133° 53° 47°
Rama09 [41]

Answer:

x = 133

Step-by-step explanation:

Supplementary angles add to 180 degrees. Call the unknown angle x

47 +x = 180

Subtract 47 from each side

47-47+x =180-47

x = 133
