Answer:
D) a four-fold increase
Explanation:
According to Gay-Lussac's law, which states that the pressure of a given amount of gas is directly proportional to the temperature at a constant volume, the pressure increases with an increase in temperature.
According to this question, at a fixed volume, a four-fold increase in the temperature of a gas will lead to a four-fold increase in the pressure as well.
Yes because Na is a metal and Cl is a nonmental, so they criss cross charges, as Na is 2+ and Cl is 2-, 2+ indicates that Na gives AWAY electrons to Cl and the 2- on Cl indicates it receiving electrons. NaCl is table salt and forms a crystal lattice structure, which is why salt is solid at room temperature.
A good night to see him again soon as I have to work tomorrow morning and I’m just gonna let go out and get it out and then I’ll head out and I can do that and then I’ll
Explanation:
When pH of the solution is 11.
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
![11=-\log[H^+]](https://tex.z-dn.net/?f=11%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=1\times 10^{-11} M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1%5Ctimes%2010%5E%7B-11%7D%20M)
..(1)
At pH = 11, the concentration of 
ions is 
.
When the pH of the solution is 6.
![pH=-\log[H^+]'](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D%27)
![6=-\log[H^+]'](https://tex.z-dn.net/?f=6%3D-%5Clog%5BH%5E%2B%5D%27)
![[H^+]'=1\times 10^{-6} M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%27%3D1%5Ctimes%2010%5E%7B-6%7D%20M)
..(2)
At pH = 6, the concentration of ions is 
.
On dividing (1) by (2).
![\frac{[H^+]}{[H^+]'}=\frac{1\times 10^{-11} M}{1\times 10^{-6}}=1\times 10^{-5}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH%5E%2B%5D%7D%7B%5BH%5E%2B%5D%27%7D%3D%5Cfrac%7B1%5Ctimes%2010%5E%7B-11%7D%20M%7D%7B1%5Ctimes%2010%5E%7B-6%7D%7D%3D1%5Ctimes%2010%5E%7B-5%7D%20)
The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is 
.
Difference between the ions at both pH:
This means that Hydrogen ions in a solution at pH = 7 has 
ions fewer than in a solution at a pH = 6
C. two billiard balls colliding and bouncing off each other
Explanation:
From the given options, the most similar scenario to the type of collision depicted in the kinetic molecular theory is the collision of the two billiard balls bouncing off each other.
Here are some of the postulates of the kinetic molecular theory:
- A gas is composed of a large number of identical molecules moving at different speeds.
- The space occupied by the gas molecules is negligible compared to the volume of the container.
- Molecules move independently of one another
- Molecules collides with one another and with the walls of the container elastically i.e without loss of kinetic energy.
- The temperature of the gas is a measure of its average kinetic energy.
