    Lead Nitrate + Sodium Iodide ---->   Sodium Nitrate + Lead Iodide (Both dissolved in water forming                        (dissolved in water) (bright yellow solid) clear solutions)                a4.  What are the products in this equation?  

    • Lead nitrate, sodium nitrate

    • sodium iodide, lead iodide

    • Sodium nitrate, lead iodide

    • Lead nitrate, sodium iodide

    Correct Answer
    A. Sodium nitrate, lead iodide
    Explanation
    The products in this equation are sodium nitrate and lead iodide.

    Lead Nitrate + Sodium Iodide             Sodium Nitrate + Lead Iodide (Both dissolved in water forming                        (dissolved in water) (bright yellow solid) clear solutions)               c5.  What has happened to the atoms of the reactants?  

    • They have recombined to form the products

    • They have changed into new atoms.

    • They have new names and places.

    • Some have been lost to the environments.

    Correct Answer
    A. They have recombined to form the products
    Explanation
    The correct answer is that the atoms of the reactants have recombined to form the products. In a chemical reaction, the atoms of the reactants rearrange their bonds to form new substances, which are the products. The reaction between lead nitrate and sodium iodide results in the formation of sodium nitrate and lead iodide. This means that the atoms from the reactants have combined in different ways to create the products.

    Vinegar is added to baking soda and bubbles of carbon dioxide rapidly form.  A cloudy liquid is left behind.  What are products in this chemical reaction?

    • Vinegar and the cloudy liquid

    • Vinegar and baking soda

    • Carbon dioxide and baking soda

    • Carbon dioxide and the cloudy liquid

    Correct Answer
    A. Carbon dioxide and the cloudy liquid
    Explanation
    When vinegar is added to baking soda, a chemical reaction occurs. Baking soda is a base, and vinegar is an acid. When they combine, they undergo a reaction called neutralization. One of the products of this reaction is carbon dioxide gas, which rapidly forms and creates bubbles. The other product is a cloudy liquid, which is a result of the reaction between the acid and base. Therefore, the correct answer is carbon dioxide and the cloudy liquid.

    Lead Nitrate + Sodium Iodide   ----->   Sodium Nitrate + Lead Iodide (Both dissolved in water forming                        (dissolved in water) (bright yellow solid) clear solutions)               b6.  What evidence shows a chemical change took place?   A.  the mass changed B.  there was liquid involved C.  a color change occurred D.  chemicals were used

    • The mass changed

    • There was liquid involved

    • A color change occurred

    • Chemicals were used

    Correct Answer
    A. A color change occurred
    Explanation
    The correct answer is C. a color change occurred. This is because the reaction between lead nitrate and sodium iodide produces lead iodide, which is a bright yellow solid. The change in color indicates that a chemical change has taken place.

    Rate this question:

  • 6. 

    How does the number and kind of atoms involved as reactants in a chemical reaction compare to the number and kind of atoms in the products?

    • There are more atoms that react

    • There are more atoms that are produced

    • There are the same number and kind of each

    • It varies from one reaction to another

    Correct Answer
    A. There are the same number and kind of each
    Explanation
    In a chemical reaction, the number and kind of atoms involved as reactants are equal to the number and kind of atoms in the products. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total number of atoms before the reaction must be equal to the total number of atoms after the reaction.
