    Question 1 (Essay)

    Write the complete balanced equation for the reaction between barium metal (Ba) and nitrogen gas (N2). You do not need to make the subscripts smaller; just write them out as regular numbers. For example: N2.

    Question 2 (Multiple Choice)

    Which of the following is a product formed when NaCl decomposes?

    Na2
    Cl
    NaC
    Cl2

    Question 3 (Multiple Choice)

    What do all decomposition reactions have in common?

    They all produce water (H2O) as one of the products.
    They all produce individual elements as the final products.
    They start with more active reactants and end with less active products.
    They start with one reactant and end with more than one product.

    Question 4 (Multiple Choice)

    Which of the following combinations of reactants will result in a synthesis reaction?

    Cl2 + HBr
    Ca + H2O
    MgO + H2O
    C2H2 + O2

    Question 5 (Multiple Choice)

    Which of the following is a synthesis reaction?

    2H2O yields 2 H2 + O2
    H2 + Cl2 yields 2 HCl
    2Li + CaO yields Li2O + Ca
    CH4 + 2 O2 yields CO2 + 2 H2O

    Question 6 (Multiple Choice)

    Which of the following is a product formed when K reacts with Cl2?

    KCl
    K2Cl
    KCl2
    K2

    Question 7 (Multiple Choice)

    Which of the following compounds will produce H2O as one of the products when it decomposes?

    Cu(OH) 2
    Hg(ClO3)2
    MgCO3
    CaO

    Question 8 (Essay)

    Write the complete balanced equation for the decomposition of Al(ClO3)3. You do not need to make your subscripts smaller; just write them out as regular numbers. For example: Al(ClO3)3.

    Answer to 614717
    4.4 chem help
    Question 1 (Essay)
    Write the complete balanced equation for the reaction between barium metal (Ba) and nitrogen gas (N2). You do not need to make the subscripts smaller; just write them out as regular numbers. For example: N2.
    3 Ba(s) + N2(g) = Ba3N2(s) Barium nitride
    Question 2 (Multiple Choice)
    Which of the following is a product formed when NaCl decomposes?
    Na2
    Cl
    NaC
    Cl2
    The correct answer is Cl2 (fourth option). Third one is a carbide, nascent chlorine does not form (second option) and sodium is not diatomic (first option).
    Question 3 (Multiple Choice)
    What do all decomposition reactions have in common?
    They all produce water (H2O) as one of the products.
    They all produce individual ...
