A sample of gas occupies 250 mL at STP. What is the temperature if the gas expands to 1500 mL at a pressure of 0.500 atm? *

3241004551 [841]

Answer:

819 K

Explanation:

Given data

Initial pressure (P₁): 1 atm (standard pressure)

Initial volume (V₁): 250 mL

Initial temperature (T₁): 273.15 K (standard temperature)

Final pressure (P₂): 0.500 atm

Final volume (V₂): 1500 mL

Final temperature (T₂): ?

We can find the final temperature using the combined gas law.

$\frac{P_1 \times V_1 }{T_1} = \frac{P_2 \times V_2 }{T_2}\\T_2 = \frac{P_2 \times V_2 \times T_1 }{P_1 \times V_1} = \frac{0.500atm \times 1500mL \times 273.15K }{1atm \times 250mL}=819K$

A titration graph shows little resistance to a change in pH at the start and has a single equivalence point of 8.6.

konstantin123 [22]

Answer: A weak acid titrated by a strong base

Explanation:

The graph refers to the titration of a weak acid such as Hydrofluoric acid with a strong base such as Sodium Hydoxide. What happens is that as the process begins, the pH rises quickly as there is little resistance to the base.

After some time the solution formed begins to act as a buffer between the remaining acid and the base. This reduces the pH change rate and will continue until the base overcomes the solution's buffering capacity.

The Equivalence point which is where the acid will be at it's base form, will be at a pH of 8.6.

I have attached a graph showing the process for better understanding.

What color has a wavelength of 6.49*10^23?

Yakvenalex [24]

Wavelength of any wave can't be equal to the number with exponential of 23, otherwise, if you're focusing on visible light, and neglecting the exponential then your color would be: orange. [ Again, remember wavelengths can be in between 10 to 10^-14 ]

In short, Your Answer would be: Orange

Hope this helps!
