Answer:
B.
Explanation:
weak acids - partially dissociate to give H+
strong acids - fully dissociate to give H+
By definition, when you divide a full rotation into 360 parts, a degree is the angle spanned by one of those parts. In contrast, on the temperature scale, a “degree” is the temperature “step” you get when you divide the temperature difference between the freezing and boiling points of water into 100 equal parts.
Answer : The average kinetic energy is, ![1.04742\times 10^{-20}J](https://tex.z-dn.net/?f=1.04742%5Ctimes%2010%5E%7B-20%7DJ)
Explanation :
The formula for average kinetic energy is:
![K.E=\frac{3}{2}kT](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B3%7D%7B2%7DkT)
where,
k = Boltzmann’s constant = ![1.38066\times 10^{-23}J/K](https://tex.z-dn.net/?f=1.38066%5Ctimes%2010%5E%7B-23%7DJ%2FK)
T = temperature = ![233^oC=273+233=506K](https://tex.z-dn.net/?f=233%5EoC%3D273%2B233%3D506K)
Now put all the given values in the above average kinetic energy formula, we get:
![K.E=\frac{3}{2}\times (1.38\times 10^{-23}J/K)\times (506K)](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B3%7D%7B2%7D%5Ctimes%20%281.38%5Ctimes%2010%5E%7B-23%7DJ%2FK%29%5Ctimes%20%28506K%29)
![K.E=1.04742\times 10^{-20}J](https://tex.z-dn.net/?f=K.E%3D1.04742%5Ctimes%2010%5E%7B-20%7DJ)
Therefore, the average kinetic energy is, ![1.04742\times 10^{-20}J](https://tex.z-dn.net/?f=1.04742%5Ctimes%2010%5E%7B-20%7DJ)
