Pushing down on the piston
causes an increase in pressure and a decrease in the volume of the gas in the
cylinder. This is BEST explained by the fact that the pressure is always
inversely proportional with volume at constant temperature and number of moles
of substance.
Answer:
9.999x10^-7M
Explanation:
First, let us calculate the concentration of the hydrogen ion in both cases:
For pH 6:
pH = —Log [H+]
6 = —Log [H+]
—6 = Log [H+]
Take the anti-log of —6
[H+] = 1x10^-6M
For pH 10:
pH = —Log [H+]
10 = —Log [H+]
—10 = Log [H+]
Take the anti-log of —10
[H+] = 1x10^-10M
The difference between the [H+] of pH 6 and [H+] of pH 10 is given by:
1x10^-6 — 1x10^-10 = 9.999x10^-7M
The frequency of collisions between the N₂ and H₂ molecules will decrease and the rate of reaction will also decrease.
Since the water is cooler than the gas mixture, heat will flow from the gas to the water.
The gas will cool down, so the average kinetic energy of the gas molecules will decrease.
The molecules will be moving more slowly, so there will be <em>fewer collisions</em> and <em>fewer of these collisions will have enough energy to react</em>.
The rate of reaction between H₂ and N₂ molecules at room temperature is exceedingly slow, <em>but cooling the gas mixture will make the reaction even slower</em>.
Answer:
C. All electron carriers are mobile and hydrophobic
Explanation:
Hello,
In this case, it is widely known that the electron carriers move inside the inner mitochondrial membrane and consequently move electrons from one to another. In such a way, they are mobile, therefore they are largely hydrophobic as long as they are inside the membrane.
For instance, the cytochrome c is a water-soluble protein in a large range, therefore, the answer is: C. All electron carriers are mobile and hydrophobic.
Best regards.
The Ancient Egyptians used simple sundials and divided days into smaller parts, and it has been suggested that as early as 1,500BC, they divided the interval between sunrise and sunset into 12 parts. ... Known as a clepsydra, it uses a flow of water to measure time.
