What is a weak acid?

Back

A weak acid is an acid that partially dissociates in solution, meaning it does not completely ionize to produce hydrogen ions (H⁺). Example: Acetic acid (CH₃COOH).

What is a limiting reactant?

Back

The limiting reactant is the substance that is completely consumed in a chemical reaction, limiting the amount of product formed. It determines the maximum yield of the reaction.

Front

What is the molar volume of a gas at standard temperature and pressure (STP)?

Back

The molar volume of a gas at STP is 22.4 liters per mole.

Front

How do you calculate the mass of a solute that can be dissolved in a solvent?

Back

The mass of a solute that can be dissolved in a solvent is determined by the solubility of the solute at a specific temperature, often expressed in grams per 100 grams of solvent.

Front

What is an electrolyte?

Back

An electrolyte is a substance that dissociates into ions when dissolved in water, allowing the solution to conduct electricity. Example: Sodium chloride (NaCl).

Front

What is the difference between strong and weak bases?

Back

Strong bases completely dissociate in solution to produce hydroxide ions (OH⁻), while weak bases only partially dissociate. Example: Sodium hydroxide (strong) vs. Ammonia (weak).

Front

What is the balanced equation for the decomposition of ammonium carbonate?

Back

(NH₄)₂CO₃ (s) → 2 NH₃ (g) + CO₂ (g) + H₂O (g)

Front

How do you determine the volume of gas produced in a reaction?

Back

The volume of gas produced can be calculated using the ideal gas law or by using stoichiometry based on the balanced chemical equation.

Front

What is solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.

Front

What is the significance of STP in gas calculations?

Back

STP (Standard Temperature and Pressure) provides a reference point for gas calculations, allowing for consistent comparisons and calculations of gas volumes.
