If vinegar is poured into two test tubes containing white powders that look identical, which of the following statements is a reasonable conclusion as to why bubbles form in one tube but not the other?

The materials in the two test tubes cannot be the same substance.

The test tubes contain two different mixtures.

The contents of the test tubes are two different pure substances.

One test tube contains an element, and the other contains a compound.

Which of these statements describes the particles of a liquid?

Particles are close together and move past each other easily.

Particles are far apart and move freely.

Particles are close together and vibrate in place.

Particles are far apart and unable to change location.

The nucleus contains and is positive.

It contains neutrons and electrons

It contains protons and neutrons

It contains protons and electrons

Which statement is NOT true of Bohr’s model of the atom?

An electron’s path is not known exactly.

The nucleus can be compared to the sun.

Electrons exist in energy levels.

According to the modern model of the atom,

moving electrons form an electron cloud.

electrons and protons circle neutrons.

neutrons have a positive charge.

the number of protons an atom has varies.

Which statement about atoms of elements in the same group of the Periodic Table is true?

They have similar chemical properties.

They have the same number of protons.

They have the same mass number.

They have the same number of total electrons.

What causes atoms to form chemical bonds with other atoms?

They want to have filled outer orbitals (octet rule).

When two atoms get close together, they merge into one.

The interaction of valence electrons forms a more stable configuration.

The attraction of the nuclei for one another causes atoms to share electrons.

Which of the following statements about covalent compounds is TRUE?

Covalent compounds generally exist as molecules.

Covalent compounds are good electrical conductors in solution.

The valence electrons are always shared equally by the two atoms in a covalent bond.

Covalent bonds generally involve two atoms that are very different, such as a metal and a nonmetal.

A chemical bond can be defined as

A force that joins atoms or ions together.

A force blending nuclei together.

A force caused by electric repulsion.

only in the protons in the nucleus.

the electrons in the outer shells.

Which of the following statements is true?

Intermolecular forces are forces of attraction between atoms.

Covalent bonds result from electrons being shared between atoms in a molecule.

Intermolecular forces determine physical properties such as the boiling point of a substance.

Chemical bonds include ionic bonds and covalent bonds.
