This double replacement reaction takes place in water. Determine the water solubility of the compounds and insert the appropriate state symbols (aq and s) into the chemical
equation. Use the solubility rules and the periodic table to help you.
Type the correct symbol in each box.

Sun is explosive itself spread 9 planets.earth is 3rd explosive in the solar system about 500 hundred million years ago . first earth became ice age and freezing climate.centre of earth magma. north zone is artic . south is anatric

The answer is 4 i don't know if its right let me see.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
