Answer:
pH =6.70
Explanation:
When Kw = 1x10^-14
[H3O+] = [OH-] --> 1x10-7
Kw =3.98x^10-14
3.98x^10-14 = [H3O+] . [OH-]
√ (3.98x^10-14) = [H3O+] = [OH-]
[H3O+] = 1.99×10^-7
- log [H3O+] = pH ---> -log 1.99x10^-7 = 6.70
Answer:
- Increased volume of particles in the container
- greater vibration of particles
Explanation:
At higher temperature, the particles of the gas would be more active and vibrate more, or even have greater collisions. Alex can indicate this in the altered model to depict higher temperature.
Consequently, Charles law gives meaning to why there would be an increased volume of gas in the stable pressurized container, if the temperature were to be increased.
I hope this explanation was clear and concise?
Mass = number of moles x molar mass
carbon dioxide: CO2
mass = 0.25 x (12 + 16 + 16)
mass = 0.25 x 44
mass = 11g
