Answer:
42.8
Explanation:
Let's consider the following reaction at equilibrium.
CO(g) + 2 H₂(g) ⇌ CH₃OH(g)
The concentration equilibrium constant (Kc) is equal to the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.
The concentration equilibrium constant for this reaction is:
Answer:
B it is decomposition reaction
Explanation:
In decomposition reaction compound is broken into two or other elements
Answer: a . is determined by the number of protons and neutrons it contains.
Explanation:
Atomic number is defined as the number of protons or the number of electrons that are present in an electrically neutral atom.
Atomic number = Number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
As the mass of electron is negligible as compared to mass of neutron and proton, the number of electrons does not influence the atomic mass of an element.
