Question 10: Which situation would react faster and why?

Without specific descriptions of Example A and Example B, it is difficult to provide a definitive answer. However, based on surface area effects in chemical reactions, the correct answer would typically be:

a. Example A would be faster because of a high surface area.

In general, reactions with higher surface areas expose more of the reactants to each other, facilitating faster reactions. This is often applicable in cases such as solids reacting with gases or liquids.

  1. products:
    a. the substances after a chemical reaction occurs

  2. reactants:
    b. the substances before a chemical reaction occurs

  3. covalent bond:
    g. a force that holds atoms together by sharing electrons

  4. electronegativity:
    c. a value that describes the relative strength with which an atom of an element attracts electrons to itself in a chemical bond.

  5. ionic bond:
    d. a force that holds oppositely charged atoms (or groups of atoms) together

  6. polar covalent bond:
    e. a force that holds atoms together by unequally shared electrons

  7. valence electrons:
    f. the electrons in the outermost orbitals of an atom
