hope it helps ;)
1: metal hydrogen gas is liberated when dilute hydrochloric acid reacts with zinc
1 hydrogen 2 co2
pop sound experiment 2 cao + co2 - caco3 it gives milky colour
Name the gas liberated when dilute hydrochloric acid reacts with zinc.
Dilute Acid + Metal → Salt + Hydrogen gas
When hydrochloric acid reacts with zinc metal hydrogen gas is liberated.
How to check presence of hydrogen gas?
→ We can check the presence of hydrogen gas by bringing a burning candle near it. If hydrogen gas is present then it will produce a pop sound, which confirms the presence of hydrogen gas.
Name the gas liberated when dilute hydrochloric acid reacts with zinc carbonate.
When hydrochloric acid reacts with zinc carbonate carbon dioxide gas is liberated.
How to check presence of carbon dioxide gas?
→ By lime water test. When carbon dioxide is passed through lime water; if it turns milky then carbon dioxide is present in it.
The reaction between hydrochloric acid and zinc carbonate.
2HCI + ZnCO3 ---> ZnCl2 + CO2 (g) + H2O
The reaction between hydrochloric acid and zinc.
2HCl + 2Zn > 2ZnCl + H2 (g).
I HOPE IT HELP YOU DEAR,
When dilute hydrochloric acid reacts with zinc it liberates Hydrogen gas.
When a burning splinter is brought near to the hydrogen gas, it puts off the burning splinter with a pop sound.
When dilute hydrochloric acid react with zinc carbonate it liberates carbon dioxide gas.
When carbon dioxide is passed through lime water it turns the lime water milky.
Dry hydrogen gas does not exhibit acidic property because, until and unless HCl comes in contact with moisture it does not produce hydrogen ions.
when an element produces hydrogen ions, then only it shows acidic properties.
Gas is a state of matter that has no fixed shape and no fixed volume. ... Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.
H2 gas i.e. hydrogen is evolved. H2 burns with a pop sound.
hope it help u.
plz make me a brainlists.
and follow me i will follow u back.
