Q: Answer the following question given this paragraph: Other applications of carbonates include glass makingwhere carbonate ions serve as a source of oxide ionsand synthesis of oxides. Hydrogen carbonates are amphoteric because they act as both weak acids and weak bases. Hydrogen carbonate ions act as acids and react with solutions of soluble hydroxides to form a carbonate and water: KHCO 3(aq) + KOH(aq) K 2 CO 3(aq) + H 2 O(l) With acids, hydrogen carbonates form a salt, carbon dioxide, and water. Baking soda (bicarbonate of soda or sodium bicarbonate) is sodium hydrogen carbonate. Baking powder contains baking soda and a solid acid such as potassium hydrogen tartrate (cream of tartar), KHC4H4O6. As long as the powder is dry, no reaction occurs; immediately after the addition of water, the acid reacts with the hydrogen carbonate ions to form carbon dioxide: HC 4 H 4 O 6 (aq) + HCO 3 (aq) C 4 H 4 O 6 2(aq) + CO 2(g) + H 2 O(l) Dough will trap the carbon dioxide, causing it to expand during baking, producing the characteristic texture of baked goods. Q: Substances that act as both weak acids and bases are said to be what? A:

OPTIONS:
- amphiphilic
- hygroscopic
- atmospheric
- amphoteric

A: amphoteric

Answer the following question given this paragraph: A lava plateau is made of a large amount of fluid lava. The lava flows over a large area and cools. This creates a large, flat surface of igneous rock. Lava plateaus may be huge. The Columbia Plateau covers over 161,000 square kilometers (63,000 square miles). It makes up parts of the states of Washington, Oregon, and Idaho. Q: When lava flows over a large area and cools, it creates a large, flat surface of what type of rock? A:
OPTIONS:
- tidal
- sedimentary
- metamorphic
- igneous
igneous
