    A recipe calls for 1 cup of milk and 4 eggs. If you only have 2 eggs, how much milk should you use?

    • 1 cup

    • 2 cups

    • 1/2 cup

    • 4 cups

    Correct Answer
    A. 1/2 cup
    Explanation
    If the recipe calls for 4 eggs and you only have 2 eggs, it means you have half of the required amount of eggs. Therefore, it would make sense to also use half of the required amount of milk, which is 1 cup. Hence, the correct answer is 1/2 cup.

    A recipe calls for one cup of milk and 4 eggs. If you want to triple the recipe, how many eggs do you need?

    • 3 cups

    • 12 eggs

    • 12 cups

    • 3 eggs

    Correct Answer
    A. 12 eggs
    Explanation
    If the recipe calls for one cup of milk and 4 eggs, and we want to triple the recipe, we need to multiply the number of eggs by 3. Therefore, 4 eggs multiplied by 3 equals 12 eggs. So, if we want to triple the recipe, we will need 12 eggs.

    A + B -> AB represents which type of reaction?

    • Synthesis

    • Decomposition

    • Single-replacement

    • Double-replacement

    • Combustion

    Correct Answer
    A. Synthesis
    Explanation
    The given chemical equation A + B -> AB represents a synthesis reaction. In a synthesis reaction, two or more reactants combine to form a single product. In this case, the reactants A and B combine to form the product AB.

    A bicycle mechanic has 10 frames and 16 wheels in the shop. How many complete bicycles can he assemble using these parts?

    • 2

    • 4

    • 6

    • 8

    • 10

    Correct Answer
    A. 8
    Explanation
    The bicycle mechanic can assemble 8 complete bicycles using the 10 frames and 16 wheels in the shop. Each bicycle requires 1 frame and 2 wheels. Since there are only 10 frames available, the mechanic can assemble a maximum of 10 bicycles. However, since each bicycle requires 2 wheels, a total of 20 wheels would be needed for all 10 bicycles. Since there are only 16 wheels available, the mechanic can only assemble 8 complete bicycles.

    Rate this question:

  • 6. 

    What is the molar mass of CH4?

    • 12 g/mol

    • 24g/mol

    • 20 g/mol

    • 16 g/mol

    • None of the above

    Correct Answer
    A. 16 g/mol
    Explanation
    The molar mass of CH4 is 16 g/mol because carbon has a molar mass of 12 g/mol and hydrogen has a molar mass of 1 g/mol. Since there are four hydrogen atoms in CH4, the total molar mass is 12 g/mol + 4 g/mol = 16 g/mol.
