Brass is a solution in which a solid is dissolved in a solid.

Option D

Explanation:

Brass is an example of alloy, a proportionate mixture of two metals: zinc and copper. Alloys are solid-solid solutions where a metal is mixed with one or more other types of metals or non-metals to form a new material, better in mechanical and chemical properties than the original components.

Increased resistance to corrosive actions, increased strength and toughness, better electrical conductivity, wider temperature operability, etc. are some advantages of alloying. Brass is widely used in manufacturing appliance parts and tools including valves, gears and bearings.  

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 number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
