Answer:C
Explanation:
Mountain Dew soda is not a colloid
10 seconds = 8grams
then just divide by 2 another 4 times...
= 0.5grams after 50 seconds
4.1 h = 14760 s
<span>t 1/2 = ln 2 / k </span>
<span>k = rate reaction = 4.97 x 10^-5 </span>
<span>ln 0.045 / 0.36 = - 4.97 x 10^-5 t </span>
<span>2.08 = 4.97 x 10^-5 t </span>
<span>t = 41839.9 s = 11 h 37 min 19 s</span>
