Step 1: grind substance into a fine powder with a mortar and pestle. step 2: add the substance to a beaker containing 300 ml of water. step 3: the mixture bubbles and a gas is emitted. the substance's ability to be ground into smaller pieces in step 1 would be classified in which area of the venn diagram? a) b) c) d)

In the Venn diagram provided, the substance's ability to be ground into smaller pieces will fall under the area;

In the Venn diagram, area A represents the physical properties of matter. More specifically, the physical property being described is density.

Density is a measure of the compactness of a substance. A substance can be tightly or loosely packed. In the description provided, the substance which was formerly tightly packed was ground till it became loose.

This is a reduction in density. Also, in a physical change, the substance does not change its constituents or observable properties.

Conclusively, the substance falls under group A in the Venn diagram.

A)  

Step-by-step explanation:

The ability of a substance to be ground into a fine powder is a physical property. Thus, it belongs in A.

That eliminates C, which represents chemical properties.

It also eliminates B, the intersection of physical and chemical properties.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
