c. 3
d. 2

2. Which statement comparing ionic and covalent bonds is correct?

a. Elements in Group 1A are more likely to form covalent bonds than ionic bonds with other atoms.
b. Covalent bonds tend to be less polar than ionic bonds.
c. More electrons are transferred from covalent bonds than ionic bonds.
d. The difference between electronegativities is greater in covalent bonds than for atoms in ionic bonds.

3. Which statement correctly compares synthesis and decomposition reactions?

a. Synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form AB → A + B, while decomposition reactions are in the form A + B → AB.
b. Synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form A + B → AB, while decomposition reactions are in the form AB → A + B.
c. Synthesis and decomposition reactions are both neutralization reactions. Synthesis reactions are in the form AB → A + B, while decomposition reactions are in the form A + B → AB.
d. Synthesis and decomposition reactions are both neutralization reactions. Synthesis reactions are in the form A + B → AB, while decomposition reactions are in the form AB → A + B.
