To move it needs a form of energy and in this case its chemical
Answer:
rA = 0.60 M/s
rC = 0.90 M/s
Explanation:
Let's consider the following reaction:
2 A+B ⇒ 3 C
The rate of each substance can be calculated like the change in its concentration divided by the change in time. Given the rate must always be positive, we add a minus sign before the reactants change in concentration.
![rA=-\frac{\Delta[A] }{\Delta t}](https://tex.z-dn.net/?f=rA%3D-%5Cfrac%7B%5CDelta%5BA%5D%20%7D%7B%5CDelta%20t%7D)
![rB=-\frac{\Delta[B] }{\Delta t}](https://tex.z-dn.net/?f=rB%3D-%5Cfrac%7B%5CDelta%5BB%5D%20%7D%7B%5CDelta%20t%7D)
![rC=\frac{\Delta[C] }{\Delta t}](https://tex.z-dn.net/?f=rC%3D%5Cfrac%7B%5CDelta%5BC%5D%20%7D%7B%5CDelta%20t%7D)
The rate of the reaction is equal to the rate of each substance divided by its stoichiometric coefficient.
The rate of disappearance of B is 0.30 M/s.
The rate of disappearance of A is:
The rate of appearance of C is:
Answer:
Explanation:
One: You could mix a small sample of it with a reactive metal. Underline small. You should see gas bubbles being given up. Usually the bubbles are hydrogen.
Example : K + HCl ===> KCl + H2
Two: You could use an indicator to watch it turn color as it goes from acidic to neutral. Litmus will go from red to blue under these conditions.
Three: Those are the two safest ways. If you knew the acid was dilute, you could put a small (underline small again) amount on your tongue. If it tastes like orange juice, it is likely an acid. This is a test every textbook mentions. You should never do it under any circumstances.
