In a forward collision, the driver and everyone else's head is thrusted back (because the energy transfer from one car to another [i.e. the Inertia] ).. the head rest is there to stop the heads from moving to far back that it could break your neck.
Answer:
nobody can answer this question because you have to draw model and you can't do it on here sorry .
Explanation:
The answer to the question is D
Answer : It takes time for the concentration to decrease to 0.100 M is, 22.4 s
Explanation :
Formula used to calculate the rate constant for zero order reaction.
The expression used is:
![\ln [A]=-kt+\ln [A_o]](https://tex.z-dn.net/?f=%5Cln%20%5BA%5D%3D-kt%2B%5Cln%20%5BA_o%5D)
where,
= initial concentration = 0.537 M
= final concentration = 0.100 M
t = time = ?
k = rate constant = 0.075 M/s
Now put all the given values in the above expression, we get:


Therefore, it takes time for the concentration to decrease to 0.100 M is, 22.4 s
C because it is two seperate mixtures I think
