Answer:

B. They have low reactivity

Explanation:

Platinum and gold are noble metals used to make jewelry.

As noble metals have little reactivity, they have a greater resistance to undergo oxidation (loss of electrons) and reduction (gain of electrons), even with extreme temperature changes. It is very common to see steel wool oxidize (corrode, change color) in the kitchen, but we hardly see this happening with a gold ring or a platinum watch, for example.

Which statement is correct about the rate of a chemical reaction? A. It increases when the concentration of reactants increases.
Natasha_Volkova [10]

Answer:

It increases when the concentration of reactants increases.

Explanation:

Increasing the concentration of reactants in a reaction increases the amount of reacting molecules or ions which would increase the rate of a chemical reaction. Reaction rate does depend on temperature. Increasing temperature also increases reaction rate because particles move faster with the increased kinetic energy to produce more collisions.

Particles that are smaller and have ____ generally dissolve faster.(1 point)
saw5 [17]

Answer:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
