Dynamic equilibrium means that the proportion is equal. The fact that the equation is at equilibrium suggests that the equation is balanced and therefore the answer must be 2.0 mol because that allows the products and reactants to level out...
Answer:
layer B is liquid because of the inner members and layer A is solid because of the outer members
Answer:
Explanation:
Every element is constituted by atoms with the same atomic number, which is the number of protons in their nuclei. So, all the atoms of a same element have the same number of protons.
For instance, the element sodium has atomic number 11, and all its atoms have 11 protons.
The atomic number identifies uniquely every element.
In the atomic nuclei there are protons and neutrons. Neutrons can vary from one atom of a particular element to another atom of the same element. That is what the term isotope accounts for. Isotopes are atoms with the same atomic number and different number of neutrons.
Most elements have different isotopes. The atomic mass of fifferent isotopes of a particular element will differ among them, because the neutrons account for the mass.
Answer:
2.78x10⁻³ m
Explanation:
Nitrogen diffusion in the steel can be expressed using the following equation:
<u>Where:</u>
J: is the diffusion flux = 1.0x10⁻⁷ kgm⁻²s⁻¹
D: is the diffusion coefficient = 1.85x10⁻¹⁰ m²/s
C₁: is the concentration of nitrogen in the steel at the surface = 2 kg/m³
C₂: is the concentration of nitrogen at the distance x₂ = 0.5 kg/m³
x₁: is the distance at the surface = 0
x₂: is the distance to find
Hence, we have:
(1)
Solving equation (1) for x₂:
Therefore, the nitrogen will enter 2.78x10⁻³ m into the sheet.
