Wind speed because speed is how fast something moves
Answer:
The rate of disappearance of 
is 0.0766 M/s.
Explanation:
Rate of the reaction = R
![R=-\frac{1}{1}\frac{d[C_2H_4]}{dt}=-\frac{1}{3}\frac{d[O_2]}{dt}](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BC_2H_4%5D%7D%7Bdt%7D%3D-%5Cfrac%7B1%7D%7B3%7D%5Cfrac%7Bd%5BO_2%5D%7D%7Bdt%7D)
[te]R=\frac{1}{2}\frac{d[CO_2]}{dt}=\frac{1}{2}\frac{d[H_2O]}{dt}[/tex]
Rate of disappearance of 
=0.23 M/s
Rate of disappearance of 
R =0.07666 M/s
Rate of disappearance of 
![\frac{d[C_2H_4]}{dt}=1\times 0.23 m/s=0.0766 M/s](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BC_2H_4%5D%7D%7Bdt%7D%3D1%5Ctimes%200.23%20m%2Fs%3D0.0766%20M%2Fs)
The rate of disappearance of is 0.0766 M/s.

Answer:
M = 0.050 M
Explanation:
WE have an acid base reaction between NaOH and HCl. The reaction is as follow:
HCl + NaOH -------> NaCl + H₂O
As we can see, we have a balanced equation already, and we can also see that the mole ratio between the HCl and NaOH is 1:1, therefore we can use the following expression:
M₁V₁ = M₂V₂ 1: acid; 2: base
This expression is used when the reactions has reached the equivalence point. As we want to know the concentration of the base, we just solve for M₂ above so:
M₂ = M₁V₁ / V₂
All we have to do now is replace the given values and solve for the concentration:
M₂ = 0.15 * 27 / 81
<h2>
M₂ = 0.050 M</h2><h2>
This is the concentration of the base</h2>
