  Chemical symbols and formulas
• What are the reactants in aerobic respiration?

  Glucose and Oxygen
• What is the chemical formula for oxygen?

  O_2
• Write the word equation for aerobic respiration.

  Glucose + Oxygen → Carbon Dioxide + Water
• Aerobic respiration produces carbon dioxide and water.

  True
• Match the substances with their definitions:

  Glucose ↔️ Sugar molecule used for energy

  Oxygen ↔️ Gas needed for respiration

  Carbon Dioxide ↔️ Waste gas produced

  Water ↔️ Another waste product
• A symbol equation is more precise than using words to describe a chemical reaction.

  True
• In aerobic respiration, glucose and oxygen are reactants.

  True
• The symbol equation for aerobic respiration is balanced because it shows the same number of atoms for each element on both sides.

  True
• What are the reactants in the given word equation?

  Glucose and Oxygen
• What does the symbol equation represent in aerobic respiration?

  Reactants and products
• The key concepts in the word equation focus on the roles of substances, while the symbol equation emphasizes their quantities.


  True
• What is the chemical formula for water?

  H2O
• The amounts of each substance involved in a reaction are shown in a symbol equation.

  True
• Match the chemical formula with its compound name:

  \(C_6H_{12}O_6\) ↔️ Glucose

  \(O_2\) ↔️ Oxygen

  \(CO_2\) ↔️ Carbon Dioxide

  \(H_2O\) ↔️ Water
• The word equation describes the substances involved in a reaction, while the symbol equation shows their chemical formulas and amounts used or produced.

  True
• What is the chemical formula for carbon dioxide?

  CO2
