Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices provided. (1) Nonbonding electron pairs are present on the F in the molecule HF. (2) The two atoms involved in a multiple covalent bond must always be atoms of the same element. (3) A molecule of hydrogen peroxide contains the same number of atoms as a molecule of sulfur trioxide does. Group of answer choices All three statements are true. None of the statements are true. Only one of the statements is true. Two of the three statements are true.

(1) Nonbonding electron pairs are present on the F in the molecule HF. True

(2) The two atoms involved in a multiple covalent bond must always be atoms of the same element. False

(3) A molecule of hydrogen peroxide contains the same number of atoms as a molecule of sulfur trioxide does. True

Two of the three statements are true.

Explanation:

Non bonding electrons are also known as lone pairs. They are electron pairs present on an atom but are not involved in chemical bonding. They are usually localized on the atom of one of the bonding elements. In HF, there are three nonbonding electrons localized on the fluorine atom that do not participate in chemical bonding.

When multiple bonds are formed between atoms, they must not be atoms of the same element, for instance carbon and nitrogen forms multiple covalent bonds in chemical moieties such as they cyanide ion.

A molecule of hydrogen peroxide (H2O2) contains four atoms just as a molecule of sulphur trioxide(SO3) does.
