Flashcard on Atomic Structure

Front

What is the relationship between starch and glucose?

Back

Starch is a polymer made of glucose monomers.

Front

What does a pH between 12 and 13 indicate about a solution?

Back

The solution is basic, meaning it has fewer hydrogen (H⁺) ions than hydroxide (OH⁻) ions.

Front

What property of water molecules allows hydrogen bonds to form?

Back

The polarity of the molecule, which involves a slightly negative oxygen atom and slightly positive hydrogen atoms.

Front

What happens to the enzyme carbonic anhydrase after it releases carbonic acid?

Back

The enzyme will repeat its function of binding reactants and releasing carbonic acid.

Front

What is the primary goal of science?

Back

To understand and explain the interactions and processes of the natural world.

Front

What is a polymer?

Back

A polymer is a large molecule made up of repeating structural units (monomers), such as starch made of glucose.

Front

What is the significance of pH in chemistry?

Back

pH measures the acidity or basicity of a solution, indicating the concentration of hydrogen ions.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy.

Front

What is the scientific method?

Back

A systematic approach to inquiry that involves making observations, forming hypotheses, conducting experiments, and drawing conclusions.

Front

What is the difference between an acid and a base?

Back

An acid increases the concentration of hydrogen ions (H⁺) in a solution, while a base decreases it.
