Answer:
Energy
Explanation:
A wave is a disturbance that transfers energy from one place to another. During this transfer of energy, matter is not usually affected. Waves can be propagated through a material medium or in a vacuum.
Waves that are propagated in a material medium are called mechanical waves.
Those propagated through a vacuum are the electromagnetic waves.

The solution is non-ideal for NaCl soln so ΔH3<span> is greater than the sum of ΔH</span>1<span> and ΔH</span>2. this means the forces of attraction between like molecules is greater than the forces of attraction between unlike molecules. <span>NaCl (table salt) dissolves readily in water. In solid NaCl, the positive sodium ions are attracted to the negative chloride ions. The same is true of the solvent, water; the partially positive hydrogen atoms are attracted to the partially negative oxygen atoms. While NaCl dissolves in water, the positive sodium cations and chloride anions are being stabilized by the water molecule electric dipoles. Thus, the intermolecular bonds between NaCl are broken and the salt is dissolved.</span>
Answer:
Statements B (1-hexene will show an absorption at 1650cm-1 but cyclohexane will not)
C (both cyclohexane and 1-hexene will show C-H absorptions at about 2950cm-1)
are both true
Answer:
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity
