  • 2. 

    Identify the type of reaction: N2 + 3H2 -----> 2NH3

    • Synthesis

    • Decomposition

    • Single Replacement

    • Double Replacement

    • Combustion

    Correct Answer
    A. Synthesis
    Explanation
    The given reaction involves the combination of two reactants, N2 and 3H2, to form a single product, 2NH3. This type of reaction is known as a synthesis reaction. In a synthesis reaction, two or more substances combine to form a more complex substance. In this case, nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3).

    Identify the type of reaction: 2H2O ---->2H2 + O2

    • Synthesis

    • Decomposition

    • Single replacement

    • Double replacement

    • Combustion

    Correct Answer
    A. Decomposition
    Explanation
     The given reaction represents a decomposition reaction. . In this reaction, two molecules of water (H2O) break down into two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2). Decomposition reactions involve the breakdown of a single compound into two or more simpler substances.

    How many nitrogen atoms are on the right side?N2 + 3H2 ----> 2NH3

    • Three

    • Two

    • Four

    • Six

    • I don't know!

    Correct Answer
    A. Two
    Explanation
    In the given chemical equation, N2 + 3H2 -> 2NH3, there are two nitrogen atoms on the right side. This is because the coefficient in front of NH3 is 2, indicating that there are two molecules of NH3 formed. Each molecule of NH3 contains one nitrogen atom, so there are a total of two nitrogen atoms on the right side of the equation.

    Identify the type of reaction: 2NaI + F2 ---> 2NaF + I2  

    • Synthesis

    • Decomposition

    • Single Replacement

    • Double Replacement

    • Combustion

    Correct Answer
    A. Single Replacement
    Explanation
    In this reaction, fluorine (F2) replaces iodine (I) in the compound sodium iodide (NaI) to form sodium fluoride (NaF) and elemental iodine (I2). This is a single replacement reaction, where a more reactive element replaces a less reactive element in a compound. Fluorine is more reactive than iodine, so it displaces iodine from sodium iodide.

    Which of the following is an example of an analysis reaction?

    • Mass spectrometry

    • Thermogravimetric analysis

    • Gravimetric analysis

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the options listed (mass spectrometry, Thermormogravimetric analysis, and Gravitational analysis ) are examples of analysis reactions. Analysis reactions involve the measurement and determination of the composition, structure, and properties of substances. In Mass spectrometry, a technique is used to identify and quantify the chemical composition of a sample. The thermogravimetric analysis measures the change in weight of a sample as a function of temperature, providing information about its thermal stability and decomposition. The gravimetric analysis involves the measurement of mass to determine the quantity of a substance in a sample.

    Identify the type of reaction: C2H6 + 5O2 ---> 3H2O + 2CO2

    • Synthesis

    • Decomposition

    • Single Replacement

    • Double Replacement

    • Combustion

    Correct Answer
    A. Combustion
    Explanation
    This reaction involves the burning of a hydrocarbon (C2H6, ethane) in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). This is a classic example of a combustion reaction, which is a type of chemical reaction that involves the rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light. Combustion reactions are often used to generate energy, such as in power plants and internal combustion engines.

    How many atoms of hydrogen are on the left side of the arrow? 2H2O ---> 2H2 + O2

    • One

    • Two

    • Four

    • Three

    Correct Answer
    A. Four
    Explanation
    In the chemical equation you provided, 2H2O —> 2H2 + O2, there are 4 atoms of hydrogen on the left side. This is because the coefficient 2 in front of H2O indicates that there are 2 molecules of water, and each molecule of water (H2O) contains 2 atoms of oxygen. So, 2 molecules of water would contain 2*2 = 4 atoms of hydrogen.

    Rate this question:

  • 9. 

    How many atoms of oxygen are on the reactant side?2H2O ---> 2H2 + O2

    • One

    • Two

    • Four

    • Three

    • I don't know!

    Correct Answer
    A. Two
    Explanation
    In the given chemical equation, 2H2O represents two molecules of water. Each water molecule contains two atoms of hydrogen and one atom of oxygen. Therefore, on the reactant side, there are two atoms of oxygen present.

    Rate this question:

  • 10. 

    How many hydrogen atoms are on the product side? N2 + 3H2 ----> 2NH3

    • Six

    • Five

    • Four

    • Three

    • Two

    Correct Answer
    A. Six
    Explanation
    In the balanced chemical equation, N2 + 3H2 -> 2NH3, it is clear that there are three molecules of H2 (hydrogen gas) on the reactant side. Each H2 molecule contains two hydrogen atoms. Therefore, the total number of hydrogen atoms on the reactant side is 3 x 2 = 6. Since the number of atoms remains the same in a chemical reaction, there will also be six hydrogen atoms on the product side.
