An unknown compound has the following chemical formula: zn(cn)x where x stands for a whole number. measurements also show that a certain sample of the unknown compound contains 9.7 mol of nitrogen and 4.9 mol of zinc. write the complete chemical formula for the unknown compound.

Explanation:

According to the law of definite proportions, particles in a compound combine by a defined stoichiometric ratio. This ratio is also calculated in terms of moles.

In order to find the ratio between the particles in a compound, we need to find the molar ratio of each species.

Notice that the ratio between the number of moles of zinc to the number of moles of nitrogen is:

This means if we are given 1 zinc ion, we expect to have a total of 2 nitrogen atoms. Therefore, x = 2.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
