Hi!
First of all, the melting of ice cream is not a chemical reaction, because there is no change in the components of the ice cream and if you freeze the ice cream again, you will get the same ice cream that you had previously.
The melting of ice cream is an example of a physical change, in which a substance goes from solid to liquid state, and it is an endothermic physical change.
When you freeze ice cream, the heat is removed from the ice cream, making it an exothermic process, when heat is liberated to the environment and it's taken away from the substance, in this case, the ice cream.
dissolves easily in water
has a high boiling point
has a high melting point
conducts electricity when melted
Explanation:
Salts are ionic compounds. Ionic compounds are formed when two atoms exchange their valence electrons. One atom gains and the other atom loses.
Generally, ionic compounds have the following properties:
- They are usually hard solids with high melting points or liquids with high boiling points.
- They are soluble in water and insoluble in non-polar solvents. This is conforms with the solubility rule that like dissolve like.
- In aqueous solution or molten form, ionic compounds conducts electricity.
- They take part in very fast chemical reactions.

Answer: The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound.
