ANSWER----
◆ When metal react with acid to give salt and hydrogen gas.
EQUATION = Metal + Acid ---- Salt and Hydrogen gas
◆ We will check hydrogen gas will released or not with the help of pop sound. PoP Sound can be tested by burning a candle and near the test tube, so we can listen pop sound so hydrogen gas is there.
◆ We will take Zinc (Zn)
Equation = Zn + 2HCl --- ZnCl2 + H2
in this above reaction ZnCl2 is salt and H2 is hydrogen gas
Zn = Zinc
HCl = Hydrochloride acid
ZnCl2 = Zinc chloride
H2 = Hydrogen
Hope it's help you....
Any doubts you can ask me....
Thank you.....
