Zinc + Hydrochloric acid is a basic metal acid reaction. When the Zinc is added to the acid, the zinc dissolves and reacts with the acid, forming hydrogen gas and the salt Zinc Chloride.
These sorts of reactions (metal + acid) will always result in a salt (in this case, zinc chloride) and hydrogen gas. The observations from this experiment would be white-gray solid is added to colorless liquid. Solid dissolves and a colorless, odorless gas is formed.
Zn + 2HCl -----> ZnCl2 + H2
Calcium carbonate is soluble in hydrochloric acid. But is difficult to dissolve in stomach a big piece of a shell.
try it.
*when putting a piece of magnesium into dilute hydrocloric acid . *then hydrogen gas bubbles off. *this shows that magnesium react quickly in acid.
You might see an extra chromosome or a missing chromosome. You might see a piece of a chromosome missing, or a piece added onto another chromosome.

Dilute hydrochloric acid will react with minerals in the sandstone, such as calcite and dolomite, causing them to dissolve. This will produce bubbles of carbon dioxide gas as a result of the chemical reaction. Over time, the acid can erode and weaken the sandstone structure.
If the acid is hydrochloric acid, the solution bubbles, and the zinc diminishes and may disappear if there's enough acid. If hydrochloric acid was used, the reaction would be Zn + HCl --> ZnCl2 + H2 . The bubbles are hydrogen gas. The zinc chloride would be dissolved in aqueous solution.
The fizzing observed is indicative of a chemical reaction occurring between magnesium and hydrochloric acid. Specifically, the magnesium is reacting with the hydrochloric acid to produce magnesium chloride and hydrogen gas. The release of hydrogen gas is responsible for the bubbling or fizzing seen during the reaction.
Well if u cut a piece nothing will happen because it is by itself if u cut it with a blade with another substance like hydrochloric acid than a reaction will happen( lights up ) but I there is no other substances mixing with it that nothing will happen
Heat and possibly become a liquid
Zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl2), a salt and hydrogen gas (H2). Marble is primarily composed of calcium carbonate (CaCO3) which reacts with hydrochloric acid (HCl) to form Calcium Chloride (CaCl2) which is a salt, water (H2O), and carbon dioxide gas (CO2). The first test tube with water evolves carbon dioxide and the second test tube with zinc granules evolves hydrogen gas.
When a piece of magnesium ribbon reacts with dilute hydrochloric acid, you would observe effervescence (bubbling) as hydrogen gas is released. The magnesium ribbon would dissolve in the acid, producing magnesium chloride solution. The solution may also become warm due to the exothermic nature of the reaction.
The steel would get warmer and possibly become a liquid.
The sandstone grains will not be affected, but the cementing material between grains could react with dilute hydrochloric acid if it is composed of calcite. Chances are, though, that the cementing material is silicate in nature, and therefore will not react with dilute hydrochloric acid.
Aluminium is amphoteric which means it react with both acids and bases. In both case Hydrogen gas is given off and the aluminum dissolves. The aluminum does actually react with the sodium hydroxide. The sodium hydroxide dissolves off the Aluminium oxide layer and then the aluminum reacts with the water. The reaction with NaOH is 2 Al +6 H20 + 2NaOH ------> 2 Na(AlOH4) + 3 H2 The Reaction with HCl is 2Al + 6 HCl ------> AlCl3 + 3 H2
When a piece of iron is placed in hydrochloric acid, the products are Iron (II) chloride and hydrogen gas.
This is an example of a single displacement reaction, where the more reactive metal (zinc) displaces the less reactive hydrogen in the hydrochloric acid to form zinc chloride and hydrogen gas.
