CBA 2 (Acids/Bases, Pure vs Mixtures, LOCM, Properties of Water

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout. Examples include saltwater and air.

Front

What is the law of conservation of mass (LOCM)?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of reactants equals the total mass of products.

Front

What are the properties of acids?

Back

Acids typically taste sour, turn blue litmus paper red, and react with metals to produce hydrogen gas.

Front

What are the properties of bases?

Back

Bases typically taste bitter, feel slippery, and turn red litmus paper blue.

Front

What is the chemical formula for potassium oxide?

Back

The chemical formula for potassium oxide is KO₂.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation.

Front

What does a coefficient in a chemical equation represent?

Back

A coefficient indicates the number of molecules or moles of a substance in a chemical reaction.

Front

What does a subscript in a chemical formula indicate?

Back

A subscript indicates the number of atoms of an element in a molecule. For example, in H₂O, the '2' indicates there are two hydrogen atoms.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Front

How many total atoms are in the photosynthesis equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂?

Back

There are 36 total atoms in the reaction.
