Someone please help with my chemistry questions??????

Ask Your Question

True or False

1. Molecules formed by covalent bonding are less stable than their constituent atoms

2. Bond dissociation energy is the enrgy needed to brake a covalent bond

3. Molecules that produce H+ ions in solutions are called acids

4. molecular solids are hard and have high melting and boiling points

5. electron pairs repel each other and determine the shape of the new molecule

6. Reactants are the substances exiting the chemical reaction

7. chemical reactions are described by chemical equations and formulas

8. direct combination reactions are also called synthesis

9. in a single replacement reaction there is only one product involved

10. analysis is also known as a decomposition reaction

Multiple choice

1. Electrons are shared unequally in a (ionic, covalent polar, covalent nonpolar) chemical bond

2. When electronegativity difference between two atoms is 0.4 to 2.0 the bond will be (ionic, covalent, not bonding)

3. in a chemical bond, atoms share (neutrons, protons, inner shell electrons, valence electrons)

4. the lewis structure shows (shared and lone pairs of electrons, only shared electrons, all electrons)
