At standard pressure when NaCl is added to water,the solution will have a

Answers

Answer: lower freezing point and a higher boiling point than water

Explanation:

Addition of a non volatile solute leads to elevation in boiling point and depression in freezing point.

This increase in boiling point arises because particles of the non-volatile solute occupy the surface of solution due to which solvent particles can not escape out of the solution.  Hence, high amount of heat is required for the solute particles to escape out of the solution. Therefore, an increase in boiling point will occur.

Also as vapor pressure of solution becomes less, the freezing point gets depressed as freezing point is the temperature at which vapor pressure of solid becomes equal to the vapor pressure of solution.

Thus at standard pressure when NaCl is added to water,the solution will have a lower freezing point and a higher boiling point than water

Explanation:

What causes water molecules to be attracted to each other? A. Polar covalent bonds inside each water molecule
B. Hydrogen bonds inside each water molecule
C. Ionic bonds between water molecules
D. Nonpolar covalent bonds between water molecules

Answers

Answer:

Both polar covalent bonds inside each water molecule and hydrogen bonds inside each water molecule are liable for attraction between water molecules.

Explanation:

  • Water is a polar protic molecule.
  • Due to large difference in electronegativity between oxygen and hydrogen atom, two O-H bonds in water molecule are polar.
  • Due to the presence of polar covalent bonds in water molecule, water molecules attract each other through oppositely polarized ends.
  • In water molecules, H atom is attached with highly electronegative oxygen atom. Hence hydrogen bonding interaction arises between water molecules.
  • So, both option (A) and (B) are correct
This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.

There can only be a net ionic reaction when a precipitate is formed as the two solutions are mixed together.

There are no net ionic equations for the given reactions as neither of them forms a precipitate.The correct  option is no reaction.

The reactions are as follows:

(NH_4)_(2)SO_4+Ba(NO_3)_2\rightarrow NH_4NO_3+BaSO_4\n

Ionic equation is defined as a chemical equation which represents electrolytes in aqueous solutions and are expressed as dissociated ions. Ions present in aqueous solutions are stabilized by ion dipole interactions with the water molecules which are present.

An ionic equation can be written for any electrolyte which dissociates and reacts with the polar solvent. In a balanced ionic equation , number and type of atoms on each sides of reaction arrow are same. Even the net charge on both sides of the arrow is same.

There can only be a net ionic reaction when a precipitate is formed as the two solutions are mixed together.Thus, the correct option is no reaction.
