Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	The initial two clear liquids
B	The resulting clear liquid and the beaker
C	The orange solid precipitate
D	All of the above

Explanation:

Detailed explanation-1: -Yes; new substances formed, as evidenced by the color changes and bubbles. Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.

Detailed explanation-2: -Yes. Why or why not? Combining the two clear colorless liquids is a chemical change because a different solid substance is formed.

Detailed explanation-3: -Tell students that sometimes when two (or more) substances are mixed together, a change occurs and another substance (or substances) is created. This is called a chemical reaction. Gas may form, heat may be produced, and color may change. These types of changes indicate that a chemical reaction has occurred.

Detailed explanation-4: -Combination reactions occur when two or more substances combine to form a new substance.
