Reactants and Products in Chemical Reactions starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Reactants and Products in Chemical Reactions.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A reaction has the following equation: N2 + 3H2 → 2NH3. Name the reactants and the product.
A reaction is represented as: C6H12O6 + 6O2 → 6CO2 + 6H2O. Name the reactants and products.
A student adds silver nitrate to sodium chloride solution and observes a white precipitate. What is the product formed as the precipitate?
A student observes that when copper(II) sulfate reacts with iron, a brown solid forms. What is the product formed?
A student writes the equation: Pb(NO3)2 + 2KI → PbI2 + 2KNO3. Identify the reactants.
Describe the difference between a reactant and a product in a chemical reaction.
Describe what is meant by the term 'stoichiometry' in relation to reactants and products.
Explain the importance of balancing chemical equations with respect to reactants and products.
Explain why catalysts are not considered reactants or products in a chemical reaction.
Explain why the identification of reactants and products is important in writing chemical equations.
In the reaction: 2Al + 3Cl2 → 2AlCl3, how many moles of AlCl3 are produced when 4 moles of Al react completely?
In the reaction: 2H2 + O2 → 2H2O, identify the products.
In the reaction: 2H2O2 → 2H2O + O2, how many molecules of O2 are produced from 4 molecules of H2O2?
In the reaction: 2Na + 2H2O → 2NaOH + H2, what are the products?
In the reaction: 2SO2 + O2 → 2SO3, how many moles of SO3 are produced from 3 moles of O2?
In the reaction: CaCO3 → CaO + CO2, which is the reactant?
In the reaction: Fe + S → FeS, identify the product.
State the law that explains why the mass of reactants equals the mass of products in a chemical reaction.
A chemical reaction is carried out in a closed system: 4NH3 + 5O2 → 4NO + 6H2O. If the total mass of reactants is 68 g, what will be the total mass of products after the reaction is complete?
Consider the following reaction: CH4 + 2O2 → CO2 + 2H2O. If 16 g of CH4 (molar mass = 16 g/mol) reacts completely, calculate the mass of H2O produced (molar mass of H2O = 18 g/mol).
