The speed of light is around 6.706×10^8 miles per hour. what is the speed of light in units of miles per minute?

Butadiene undergoes a reaction at a certain temperature in the gas phase as follows: 2c4h6(g) --> c8h12(g) the following data were collected for this reaction: time (min) [c4h6] (m) 0 0.36 15 0.30 30 0.25 48 0.19 75 0. determine the order of the reaction and the rate constant. 1st order and k = 4.3x10 -4 s-1 1st order and k = 2.3x10-4 s-1 2nd order and k = 4.3x10-4 s-1 2nd order and k = 2.3x10-4 s-1 zero and k = 4.3x10-4 s-1

Need ! assume that the variables x and y are directly related. if k = 8, what is the value for each of the following points? be sure and record your data to be used in the following problem. x y k 0.
