Answer: Three
When the reactant concentration is increased, generally the reaction rate will be increased too. But the magnitude of the increase can differ in various reaction. In this case, 2x concentration will result in 8x reaction rate. The order will be:
2^x= 8
2^x= 2^3
x=3
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Answer : The pH of the solution is, 5.01
Explanation :
For acetic acid : 
First we have to calculate the concentration of acetic acid and sodium acetate.
Concentration of acetic acid (Acid) = 
Concentration of sodium acetate (salt) = 
Now we have to calculate the pH of the solution.
Using Henderson Hesselbach equation :
![pH=pK_a+\log \frac{[Salt]}{[Acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%20%5Cfrac%7B%5BSalt%5D%7D%7B%5BAcid%5D%7D)
Now put all the given values in this expression, we get:


Therefore, the pH of the solution is, 5.01
