Answer:Standard Pressure is 1 Atm, 101.3kPa or 760 mmHg or torr.
STP is the "standard" conditions often used for measuring gas density and volume. At STP, 1 mole of any gas occupies 22.4L.
Explanation:
Answer:
The molar average velocity is 0.0588 cm/s
The N₂ diffusion velocity relative to the mole average velocity is -0.1428 cm/s
The molar diffusional flux of N₂ is -3.9x10⁻³
Explanation:
Given data:
T = temperature = 265 K
O₂ = 25%
N₂ = 60%
CO₂ = 15%
vO₂ = -0.084 cm/s
vN₂ = 0.12 cm/s
vCO₂ = 0.052 cm/s
The molar average velocity is equal:
The N₂ diffusion velocity relative to the molar average velocity is:
The molar diffusional flux of N₂ is:
Answer:
I think it's B
Explanation:
I think it is b because if the number is positive the zeroes will be on the left so you move the decimal to the right to get rid of the zeroes.
Answer:
189.5
Explanation:
its very very very very easy
Answer:
12, 28, 16
Explanation:
If we are trying to find mass, neutrons are our guy. 28 "mass points" means 28 neutrons. Each neutron is one point
We know there are 12 protons and electrons if we look at a table of elements, the number in the top-left is always the number of protons and we can subtract mass from the protons to get our electrons
