For 1: The correct answer is True.

For 2: The correct answer is True.

For 3: The correct answer is False.

For 4: The correct answer is False.

For 5: The correct answer is True.

Explanation:

Ionic compounds are formed when there is complete transfer of electrons from one element to another element to form a compound. The element which looses electrons is known as electropositive element and tend to form cation and the element which gains electrons is known as electronegative element and tend to form anion.

These compounds are generally crystalline solids at room temperature.

These compounds are electrically neutral species. Total negative charge is always equal to the total positive charge.

As, there is electrostatic attraction between the charged species, therefore they form stronger bonds and to break these bonds, more and more amount of energy is require. Hence, these compounds have high melting as well as boiling points.

When these compounds are melted, the ions get separated and the solution contains free ions which tend to conduct electricity very easily. Hence, ionic compounds do conduct electricity when they are melted.

Therefore, from the above information:

For 1: The correct answer is True.

For 2: The correct answer is True.

For 3: The correct answer is False.

For 4: The correct answer is False.

For 5: The correct answer is True.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
