Answer 1

Answer:

zinc chloride forms when zinc is added to hydrochloric acid. Also , hydrogen gas is liberated.

Answer 2

QUESTION:-

What would you observe when zinc is added to a dilute hydrochloric acid? Write the chemical change reaction that takes place.

ANSWER:-

The Observation When Zinc Is Added To A Dilute Hydrochloric Acid

• Then the conical flask becomes hot which means that a change in temperature has also occurred in this chemical reaction. This is because a lot of heat energy is being released.

• This reaction in which heat is evolved is known as exothermic reaction.

• The bubbles of hydrogen are formed around zinc granules.

• Hydrogen gas evolved as precipitation.

• On testing, the gas is found to be hydrogen and burns with a pop sound.

The chemical change reaction that takes place when zinc is added to a dilute hydrochloric acid is:-

• [tex] Zn + 2HCl -> ZnCl2 + H2 (precipitated)[tex/]
