Zn + 2HCl --> ZnCl2 + H2
What you can see is the hydrogen gas effusing out of the solution in many bubbles.
It bubbles and creates zinc chloride and hydrogen.The zinc chloride, ZnCl2 is formed.
Answer:Metal + Acid --> Salt + HydrogenZinc + Hydrochloric Acid --> Zinc Chloride + HydrogenUnbalanced Equation:Zn + HCL --> ZnCL + HBalanced Equation:Zn + 2HCL --> ZnCl2 + H2The balanced equation is the one you should write for exams.Explantion:Zinc has 2 valence electrons (2 in its outer shell), so it more easily loses the two electrons, to form a zinc ion (Zn2+).Hydrochloric Acid (HCl) has a minus one charge (HCl-).To balance it, you need 2 HCl's to balance it with zinc's 2+ charge, so you add a "2" before the HCl (see balanced equation).On the other side of the equation, you have ZnCl2 (because there are now 2 chlorine atoms, and H2 (2 hydrogen atoms).Hydrogen comes in H2 form (two atoms bonded together), so when a reaction forms hydrogen as a product, you know you need at least two of them on the left side of the equation.
When mossy zinc is placed in dilute sulfuric acid (H2SO4) solution, a chemical reaction occurs where zinc reacts with sulfuric acid to produce zinc sulfate and hydrogen gas. This reaction is a single displacement reaction where zinc displaces hydrogen from the acid. The resulting solution will contain zinc sulfate and bubbles of hydrogen gas will be observed.
If a gold ring is put in dilute acid, such as hydrochloric acid, the gold will not react as gold is a noble metal and is resistant to corrosion by acids. However, if the acid is concentrated or a different type of acid, such as aqua regia, gold can dissolve due to the formation of gold ions.
What happens??? It reacts!!!! You will see effervescence(bubbles) of hydrogen gas being liberates, and the zinc metal slowly disappearing. Here is the Balanced reaction eq'n Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g) .
Get these things: some hydrochloric acid some zinc strips a clear plastic bottle that's got a small neck like a soda bottle, but that isn't a food bottle--this is so someone won't put food in it later and kill themselves a balloon Wear normal lab safety stuff--apron, face shield and rubber gloves. Wash the bottle out and put hydrochloric acid in it. Put the zinc strips in the acid. Wait till it bubbles for a few minutes, then put the balloon over the neck of the bottle. The balloon will be filled with hydrogen. (You give it the few minutes so the hydrogen can push the air out of the bottle. The equation's pretty simple: HCl + Zn = ZnCl + H
Put a few drops of dilute hydrochloric acid on both samples. Both will fizz indicating the presence of calcite.
if you put aluminum foil on hydrochloric acid it can flow joke! hehe
If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.
you put the hydrochloric acid in a test tube then you put the magnesium metal in the test tube with the hydrochloric acid in it then you put a cork on the top ofthe test tube and watch it fizz.
When sulfur is put into hydrochloric acid, a chemical reaction occurs where sulfur reacts with hydrochloric acid to form hydrogen sulfide gas and sulfur dichloride. The reaction is as follows: S + 2HCl -> H2S + SCl2
NaHCO3 + HCl(l) ---> Na(aq) + H2 + Cl(aq) + CO2. The products are aqueous sodium and chloride (though not technically correct, they are often put together in most descriptions), hydrogen gas and carbon dioxide.
