These reactions are irreversibles.
There is no symbol. The word is neutralisation.
Reversible Reaction
When magnesium reacts with sulfuric acid, you would observe the production of hydrogen gas bubbles, the magnesium metal dissolving or reacting to form magnesium sulfate, and the solution becoming warmer due to the exothermic nature of the reaction.
I am guessing that you mean hydrochloric acid, and the reaction is ammonia plus hydrochloric acid gives ammonium chloride; NH3 + HCl => NH4Cl
The general equation for a metal reacting with an acid is: Metal + Acid → Salt + Hydrogen gas
There is no symbol. The word is neutralisation.
Dissolving zinc in acid is a chemical change. It really isn't being dissolved, it is reacting with the acid to form new substances. For example, if you react zinc with hydrochloric acid, the products will be zinc chloride and hydrogen gas. The zinc seems to dissolve, but it is actually combining with the chlorine in the hydrochloric acid. Zn + 2HCl ---> ZnCl2 + H2
Acid Carbon reacting
Reversible Reaction
Zinc chloride is typically made by reacting zinc with hydrogen chloride gas. It can also be produced by dissolving zinc oxide or zinc metal in hydrochloric acid.
The lipid bilayer prevents the cell from dissolving in water.
Carbon dioxide is neither an alkali nor a base. It is actually an oxide of carbon, and in aqueous solutions, it forms carbonic acid (H2CO3) by reacting with water.
Its a chemical change. its like an acid reacting with a base to form salt and water.
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
It is a chemical property.
When magnesium reacts with sulfuric acid, you would observe the production of hydrogen gas bubbles, the magnesium metal dissolving or reacting to form magnesium sulfate, and the solution becoming warmer due to the exothermic nature of the reaction.
Chemical changes that involve physical changes, such as melting, boiling, or dissolving, are generally reversible. Reactions involving phase changes or reversible reactions where products can revert back to reactants under certain conditions are reversible. An example is the reaction between water and carbon dioxide to form carbonic acid, which can decompose back into water and carbon dioxide.
