Answer 1

The correct statement comparing ionic and covalent bonds is:

Covalent bonds tend to be less polar than ionic bonds.

In general, ionic bonds arise from the transfer of electrons between atoms with a significant difference in electronegativity, typically between metals and nonmetals, leading to the formation of charged ions. This results in a highly polar bond. In contrast, covalent bonds involve the sharing of electrons between atoms, often with smaller differences in electronegativity, making them less polar on average.

The other statements are incorrect for the following reasons:

1. The difference in electronegativities is generally greater for atoms in ionic bonds compared to covalent bonds.
2. Elements in Group IA (alkali metals) are more likely to form ionic bonds because they tend to lose their single valence electron to achieve a stable electron configuration.
3. In ionic bonds, electrons are transferred from one atom to another, while covalent bonds involve the sharing of electrons, so more electrons are typically transferred in ionic bonding, not covalent.

Answer 2

Acid-base reactions can also
be classified as which type of
reaction? (1 point)
double replacement
single replacement
decomposition
synthesis

Answer 3

Acid-base reactions can be classified as double replacement reactions.

In a typical acid-base reaction, the acid donates a proton (H⁺), and the base accepts the proton, resulting in the formation of water and a salt. This involves the exchange (or "replacement") of ions between the acid and the base, which is characteristic of double replacement reactions.
