c. make a prediction: will mixing copper with zinc to make brass speed up or slow down the rate at which the metal mixture reacts with oxygen in the air?

c. make a prediction: will mixing copper with zinc to make brass speed up or slow down the rate at which the metal mixture reacts with oxygen in the air?

Answer

Brief Explanations:

Brass is an alloy of copper and zinc. Alloys often have different reactivity compared to their constituent metals. Pure zinc is more reactive than copper and reacts with oxygen (oxidation) relatively quickly. When zinc is alloyed with copper to form brass, the structure and electron distribution change. The presence of less - reactive copper in the alloy disrupts the uniform reactivity of zinc. This disruption leads to a decrease in the rate of reaction with oxygen. So, mixing copper with zinc to make brass should slow down the rate at which the metal mixture reacts with oxygen in the air.

Answer:

Mixing copper with zinc to make brass will slow down the rate at which the metal mixture reacts with oxygen in the air.
