When a piece of marble, primarily calcium carbonate (Caco.), is dropped into hydrochloric acid (HCI), a few bubbles form. An equal mass of powdered marble, however, reacts rapidly, forming many gas bubbles Why?

The marble powder has a coating of oxygen atoms form the air, which causes the bubbles..
The marble powder has much more surface area, so the acid comes into contact with more calcium carbonate.
The marble powder has more atoms than the solid marble, so the powder reaction proceeds faster.
The marble powder has a different molecular structure that is more reactive than a solid piece of marble.
