please help me I will mark as brainlest answer​

Answer 1

1. yes because ice is in solid state and cold energy is required to transfer it into solid state from liquid state....And that's how the solid ice is melt down into water by applying heat energy.

Answer 2

Answer:

1.Answer: Ice is more effective in cooling than water at the same temperature because ice can absorb latent heat as well as the heat energy in order to attain room temperature. Water at 0 C can absorb heat energy only to attain the room temperature.

2.Answer: A strong acid is one that fully dissociates to form H3O+ ions in aqueous solution, where as a weak acid only does so partially. A concentrated acid, on the other hand, is one that has a very high concentration of H3O+ ions in aqueous solution.

4.Answer: A deposit of insoluble residue formed from the dissolution of the anode in commercial electrolysis. Sometimes called anode slime. In copper refining, this slime contains the precious metals that are recovered from it..

3.A neutralization reaction is when an acid and a base react to form water and salt and involves the combination of hydrogen ions and hydroxyl ions to generate water. ... Example – 1: When Sodium hydroxide is added to hydrochloric acid. Sodium chloride and water are formed.
