Since each of the substances conduct electricity except A, it is the least likely to be metallic. Additionally, it is a powder, which is unlike most metals, and has an extremely high melting point much above many metal substances and very different from the other substances tested.
Chemical weathering can be caused by oxidation, dissolution, and hydrolysis
Answer:
Fewer bubbles will be produced because of fewer collisions of reactant molecules
Explanation:
As the solid dissolves into the solution after the liquid has been vigorously bubbled, if the temperature of the liquid is reduced a little, what will happen is that fewer bubbles will be produced as a result of lesser amount of collisions occurring between the reactant molecules
