if the mass of a box was 400 grams, and the length is 2cm the width is 2cm and the height is 1cm. what is the density?

The density of the box is 6.25g/cm³

Explanation:

400 ÷ 4³ = 6.25

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).

you need to give more information
