List at least three different properties that would help you determine whether the bars are made of the same metal.

Refractive index

Heat capacity

Density

Explanation:

Properties that are used to identify materials are called intensive properties. These intensive properties are characteristic of the material and does not depend on the amount of material present.

Thus, if i want to identify whether the three bars are made of the same metal, i can look out for the following properties;

Refractive index

Heat capacity

Density

These properties are intensive properties thus they can be used to identify an unknown substance.

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:

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
