Answer:
CuCl2-Ion-dipole forces
CuSO4-Ion-dipole forces
NH3-Dipole-dipole forces
CH3OH-Dipole-dipole forces
Explanation:
Water consists of a dipole. The water molecule contains a positive end and a negative end. The positive ion attracts the negative dipole of water while the positive dipole in water interacts with the negative ion of an ionic substance. This explains the dissolution of ionic substances in water.
Copper II chloride and copper sulphate are ionic substances hence they dissolve by the mechanism described above.
Molecules consisting of dipoles dissolves by interaction of the molecule's dipoles with the dipoles in water. For example, methanol interacts with water through hydrogen bonding which is involves molecular dipoles
The metric system of units is known as the International System of Units (ISU).
Explanation:
Water molecules are polar, so they form hydrogen bonds. This is a unique property of water. Water has an unique boiling point and high polarity.
Explanation:
A source Emits a sound and is represented by the red dot in this map. Four people are located and the source and the circle represent the sound wave.
As the source moves west which person hears the highest pitch
person B
