Question

chemical reaction and equation lesson activity 1.4 take a small amount of clacium oxide or quick lime in a breaker slowly add water to this touch the beaker do you feel change in temperature observation​

Answer 1

Answer:

The temperature raises and the beaker becomes hot because large amount of heat is released .

Answer 2

Answer:

The observed reaction during this experiment is exothermic and thus, the temperature of the beaker rises.

Explanation:

• It is an exothermic reaction because calcium oxide combines forcefully with water to create slaked lime (calcium hydroxide), which releases a lot of heat. It is a combination reaction, and after it is finished, a clear solution is obtained at the top.
• Calcium oxide reacts vigorously with water to form calcium hydroxide (also known as slaked lime) when water is slowly added to a small amount of calcium oxide placed in a beaker.
• Significant amount of heat is released. So, the reaction is exothermic.
• The temperature of quicklime rises when water is introduced.
• An illustration of an exothermic process is this.
• Calcium oxide from quick lime interacts violently with water to generate calcium hydroxide while producing a significant quantity of heat.
