  • 2. 

    ____ K2SO3 + ____ Mn(OH)2 --> ____ KOH + ____ MnSO3 What kind of reaction does the above equation represent?

    • Synthesis

    • Decomposition

    • Single replacement

    • Double replacement

    Correct Answer
    A. Double replacement
    Explanation
    The given equation represents a double replacement reaction. In a double replacement reaction, the positive and negative ions of two compounds switch places to form new compounds. In this equation, the potassium ions from K2SO3 switch places with the hydroxide ions from Mn(OH)2 to form KOH, and the sulfite ions from K2SO3 switch places with the manganese ions from Mn(OH)2 to form MnSO3.

  • 3. 

    What type of reaction is this? ____ Br2 + ____ LiF -->  ____ LiBr + ____ F2

    • Synthesis

    • Decomposition

    • Single replacement

    • Double replacement

    Correct Answer
    A. Single replacement
    Explanation
    In this reaction, a single element (Br2) replaces another element (F) in a compound (LiF). This type of reaction is known as a single replacement reaction.

    Rate this question:

  • 4. 

    What are the correct coefficients for the following equation? ____ Br2 + ____ LiF -->  ____ LiBr + ____ F2

    • 2, 4, 4, 2

    • 1, 2, 3, 1

    • 1, 2, 2, 1

    Correct Answer
    A. 1, 2, 2, 1
    Explanation
    The equation represents the reaction between bromine (Br2) and lithium fluoride (LiF) to form lithium bromide (LiBr) and fluorine (F2). To balance the equation, we need to ensure that the number of each type of atom is the same on both sides. In this case, there are 2 bromine atoms on the left side, so we need 2 LiBr molecules on the right side to balance it. Similarly, there are 2 fluorine atoms on the right side, so we need 2 F2 molecules on the left side. Therefore, the correct coefficients for the equation are 1, 2, 2, 1.

    Rate this question:

  • 5. 

    ____ Ni(OH)3 --> ____ Ni2O3 + ____ H2OWhen the above equation is balanced, what is the coefficient for nickle (III) oxide?  

    • 2

    • 1

    • 3

    Correct Answer
    A. 1
    Explanation
    In the balanced equation, the coefficient for nickel (III) oxide is 1. This means that for every 1 molecule of nickel (III) oxide, there are 1 molecule of nickel hydroxide and 3 molecules of water.
