Question

A student took 2-3 g of a substance X in a glass beaker & poured water over it slowly.
He observed bubbles along with hissing noise. The beaker becomes quite hot. Identify
X. What type of reaction is it?​

Answer 1

Answer:

hope this answer helps

Explanation:

A student took 2 - 3 g of substance x in a glass beaker and poured water over it slowly. He observed bubbles along with a hissing noise. ... The substance is X is quicklime or calcium oxide. Calcium oxide when mixed with water reacts with it to form calcium hydroxide, also known as slaked lime.

Answer 2

Answer:

The reaction is exothermic.

Explanation:

• An exothermic reaction is a chemical reaction that occurs when a substance produces energy and generates heat. The new bonds are formed during exothermic reactions.
• An exothermic reaction occurs when a student adds water slowly to 2–3 g of drug X in a glass beaker.
• The students heard a hissing sound and saw bubbles in the beaker.
• The substance X is known as calcium oxide or quicklime.
• When calcium oxide reacts with water to produce calcium hydroxide, it releases heat. The reaction is an exothermic one because it generates a lot of heat.
• Calcium hydroxide is also referred to as "slaked lime."
