The equilibrium concentration of N₂ : 1.992
<h3>Further explanation</h3>
Given
Kc = 6.0 x 10⁻² at 500°C
0.253 M H₂ and 0.044 M NH₃
Reaction
3H₂(g) + N₂(g) = 2NH₃(g)
Required
The equilibrium concentration of N₂
Solution
Kc for the reaction :
4 becuase they absorb a little amount
23 Sandwiches
Slices of cheese
6 slices of bread
0 slices of cheese
I think this is right.
Hope this helps :)
Answer: The correct answer is mass number.
Explanation:
An isotope is a chemical compound of the same element which only differ in the number of neutrons. The number of protons and electrons remain same for two isotopes. This means isotopes have different mass number but have same atomic number.
When we write an isotope, the number at the end of the isotope's name is the mass number.
When writing an isotope: Chlorine-35, the number 35 represents the atomic mass and not atomic number.
Hence, the correct answer is mass number.
Answer: Equilibrium
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction which means the products are being made as quickly as reactants
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
