Silver iodide powder has been used as an antiseptic and as an agent to seed clouds for rain. Silver iodide is 45.9% silver by mass. If you separate a 50.0-g sample of silver iodide into its elements, silver and iodine, how much silver would you have?

22.95g

Explanation:

Given parameters:

Percentage by mass of silver in silver iodide  = 45.9%

Mass of silver iodide given  = 50g

Unknown:

Mass of silver in silver iodide  = ?

Solution:

The formula of the compound is;

 Silver iodide  = AgI

       Since the percentage by mass of silver in the compound is 45.9%;

 Mass of silver  = percentage by mass of silver x mass of AgI

 Mass of silver  = x 50  = 22.95g

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).

explanation:

the answer is 1 i believe
