Which of the following compounds in the main group is a metalloid? A. Arsenic
B. Potassium
C. Chlorine
D. Indium

A. Arsenic

Explanation:

Arsenic is a metalloid. Arsenic has properties of both metals and non-metals that is why it is a metalloid.

Potassium, chlorine, and indium do not have both properties of metals and non-metals, therefore they are not metalloids.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
