Answer:
B
Explanation:
Because the tax was imposed to tanning consumers, the demand will be affected and not the supply ( because the tax was not imposed for producers). With the new tax, the price of using tanning beds will increase. This will lead to a decrease in demand because less people are willing to pay the extra imposed by the tax. In the demand and supply graph for the tanning beds market, the demand curve will shift to the left.
<span>What most distinguishes noise from music is the presence
of Regularity. Both of these relate to human power of hearing, the difference
is that music is an arranged form of sounds which appeals to the aesthetic
sense of human being while noise is a series of sounds with no regularity or
harmony in it. Music and noise both have their good side as well as bad, with a
common fact that any of them can be harmful for human ear when it is at a very loud
frequency. </span>
Answer:
A
Explanation:
The Germans wanted to focus on and keep watch of the Jews by creating camps.
Explanation:
A + B + C → D
Given rate law of the reaction :
![R=k[A]^2[B]](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E2%5BB%5D)
a) Rate of the reaction if [A] is doubled = R'
![R'=k[2A]^2[B]=4k[A]^2[B]](https://tex.z-dn.net/?f=R%27%3Dk%5B2A%5D%5E2%5BB%5D%3D4k%5BA%5D%5E2%5BB%5D)
R' = 4 × R
The rate of the reaction will change by factor of 4.
b) Rate of the reaction if [B] is reduced to quarter = R'
![R'=k[A]^2[\frac{B}{4}]=0.25k[A]^2[B]](https://tex.z-dn.net/?f=R%27%3Dk%5BA%5D%5E2%5B%5Cfrac%7BB%7D%7B4%7D%5D%3D0.25k%5BA%5D%5E2%5BB%5D)
R' = 0.25 × R
The rate of the reaction will change by factor of 0.25.
c) Rate of the reaction if [C] is increased by 3 times= R'
Rate law of the reaction :
![R'=k[A]^2[B]](https://tex.z-dn.net/?f=R%27%3Dk%5BA%5D%5E2%5BB%5D)
As we can see that [C] does not appears in rate law of the reaction, which means that rte of the reaction is independent of [C].
R' = R
The rate of the reaction will remain the same.
The expected rate constant value for this experiment:
![k=\frac{R}{[A]^2[B]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7BR%7D%7B%5BA%5D%5E2%5BB%5D%7D)
