Color of zinc granules after reaction with dilute hcl?
Black
What is the change in color of zinc granules when it reacts with HCL?
Black ^^
Zinc granules are treated with dilute hydrocholoric?
When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.
Whats made when you react zinc granules and dilute acid?
When dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.
What happens when dilute sulfuric acid is added over zinc granules?
coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.

Does a new penny float in hcl?
when the penny is reacted with HCl, there must be somesort of area where the copper on the outside of the penny is removed so that the HCl can react with the zinc inside because HCl does not react with copper. Once the HCl reacts with the Zn inside, it will dissapear and therefore become less dense then the ZnCl2 that is formed which causes the penny to float

Why does a zinc penny not react in hydrochloric acid?
The zinc in the core of the penny will react in a single replacement reaction with the hcl while the copper will not theoretically react and will be left behind. So if you soak a penny, with cuts in it for the hcl to reach the zinc, will leave behind a copper shell. -may not be 100%correct as i am not an expert just taking high school chem.
Why is HCL gas not an acid but HCL aqueous an acid?
becoz HCL aqueous s has an ability to react with bases and it changes the blue litmus in to red colour hence HCL gas is noit an acid but HCL aqueous an acid.
Which metal react with dilute hcl?
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
What chemical reactions occur when HCl is added to Zn?
The hydrochloric acid will react with the zinc to produce zinc chloride and hydrogen gas. It looks like this: 2HCl + Zn => ZnCl2 + H2
Why HCl react with NaCl?
NaCl and HCl doesn't react.
How zinc react with acid?
Use any acid. HCl, HBr, HX. Zn + HX ==> ZnX + H2. The zinc forms a salt with the acid by getting oxidized. Hydrogen gas is released. With hydrochloric acid, the reaction is as follows: Zn + HCl ==> ZnCl2 + H2
