We take activities of Solids and liquids equal 1. The reason is there concentrations not at all change amount of reactant at equilibrium in the reaction. Hence we don't consider concentrations of pure solids and liquids while writing equilibrium constant.
So for above reaction, equilibrium constant (K) = [Sn^2 +] ^3 x 1 / [Fe^3+]^2 x 1. Ping me if you have any doubts.
We need more information to answer this.
The answer should be 2) electrons.
The elements in the periodic table are arranged by increasing atomic number, which is also the number of protons in an element. For example, Carbon has 6 protons, it is the sixth element on the table. While Nitrogen, which has 7 protons, is after Carbon.
In atoms, the number of protons equals to the number of electrons too, if the number of electrons does not equal to the number of protons, the substance is no longer atom, but ion. So, the answer to this is 2) electrons, as the elements on the table is arranged according to increasing atomic numbers.
Answer:
3
Explanation:
The amount of mass per given vol
Answer:
A mixture is created when two or more different substances are physically combined and can be separated back into its original substances. A chemical reaction occurs when two or more substances are combined to form a new substance and cannot be separated back into its original substances.
