Topic #3: "It's Chemistry!" flashcard #1

Front

What happens to the temperature of water when dissolving tablets in a chemical reaction?

Back

The temperature of the water may increase or decrease depending on whether the reaction is exothermic (releases heat) or endothermic (absorbs heat).

Front

What occurs when acetic acid (vinegar) and sodium bicarbonate (baking soda) are combined?

Back

An acid-base reaction occurs, forming the salt sodium acetate and carbonic acid.

Front

Define a chemical reaction.

Back

A chemical reaction is a process where two or more molecules/substances interact to form one or more different molecules/substances.

Front

What is the main idea of the text 'A Fizzy Reaction'?

Back

Combining vinegar and baking soda leads to an acid-base reaction and a decomposition reaction, which are important types of chemical reactions.

Front

How do vinegar and baking soda work together in baking?

Back

Using baking soda and vinegar together in baked goods releases carbon dioxide gas, which creates an airy texture in foods.

Front

What is an acid-base reaction?

Back

An acid-base reaction is a chemical reaction that occurs between an acid and a base, resulting in the formation of a salt and water.

Front

What is carbon dioxide?

Back

Carbon dioxide is a colorless, odorless gas produced during the reaction of vinegar and baking soda, which causes bubbling.

Front

What is sodium acetate?

Back

Sodium acetate is the salt formed when acetic acid reacts with sodium bicarbonate.

Front

What is the role of carbonic acid in the reaction between vinegar and baking soda?

Back

Carbonic acid decomposes to produce carbon dioxide and water, contributing to the fizzing effect.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler substances.
