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:
2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.
It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.
Answer:
Coefficient = 3
Subscript for Mg = 1
Subscript for Cl = 2
Explanation:
Coefficient:
A coefficient is number before the chemical formula which tells the number of molecules take part in chemical reaction.
For example:
2H₂ + O₂ → 2H₂O
In this reaction 2 moles of hydrogen react with one mole of oxygen and produce 2 mole of water. The number 2, 1 and 2 are the coefficient.
In given formula 3MgCl₂ the number before the formula which is three is coefficient.
While the number written as subscript tell about the number of atoms of elements. e.g.in MgCl₂ two atoms of chlorine and one atom of magnesium are present in given formula. If only one atom of particular element is present then it is not written as subscript.
