Acid a compound that donates protons to a base Base a chemical compound that accepts protons from an acid Catalyst a substance that increases the rate of a chemical reaction without being permanently altered by the reaction Chemical change a change that results in the formation of new substances Coefficient a number that multiplies a term in an equation Conservation of matter a scientific law that states that the total amount of matter in a closed system ...

A white powder is added to a solution. The images show observations made before the powder is added, just after the powder has been added, and a little while later. (The liquid in the small beaker is phenol red solution.) What evidence shows that a chemical change has taken place? Correct Answer: D. All of the above. A reaction produces a gas, which is collected in a glass cylinder. When a glowing splint is placed inside the container, it burns brightly, as shown. Which gas was produced ...
