Answer:
Does the wave require a medium in order to travel?
Explanation:
The question whose answer would determine whether the wave in question is mechanical or electromagnetic would be <u>if the wave requires a medium in order to travel or otherwise.</u>
<em>A mechanical wave would require a medium in order to transport its energy from one place to another, that is, travel. On the other hand, an electromagnetic wave does not require any medium in order to travel, that is, it can travel through vacuums or empty spaces</em>. <u>Light</u> and <u>sound waves</u> are typical examples of <u>electromagnetic</u> and <u>mechanical waves</u> respectively.
Explanation:
It is known that for first order reaction, the equation is as follows.
t = ![\frac{2.303}{K} log \frac{[C_{4}H_{8}]_{o}}{[C_{4}H_{8}]_{t}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.303%7D%7BK%7D%20log%20%5Cfrac%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bo%7D%7D%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bt%7D%7D)
t = ?, K = rate constant = 79 1/s
Initial conc. of
= 1.68
Decompose amount of
= 52% of 1.68
= 
= 0.8736
= 0.87
Now,
= (1.68 - 0.87)
= 0.81
Therefore, calculate the value of t as follows.
t = ![\frac{2.303}{K} log \frac{[C_{4}H_{8}]_{o}}{[C_{4}H_{8}]_{t}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.303%7D%7BK%7D%20log%20%5Cfrac%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bo%7D%7D%7B%5BC_%7B4%7DH_%7B8%7D%5D_%7Bt%7D%7D)
= 
= 
=
s
= 
Thus, we can conclude that 0.00921 s will be taken for 52% of the cyclobutane to decompose.
The answer is 83% percent
I hope I am right on this, but the answer is
Fe₂O₃ + 3CO --> 2Fe + 3CO₃
