What do you mean by H2 and 2H?
molecular hydrogen
H2 is molecular hydrogen. It is bonded together by one single bond. 2H denotes two moles of elemental hydrogen . Two separate hydrogen atoms that are not combined as a unit.
How is the acidity of a solution determined?
An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution.
How is the reaction between a metal and an acid represented?
The reaction between a metal and an acid can be represented by the general word equation shown below: acid + metal → salt + hydrogen gas The name of the salt is determined by the metal and the acid used: Please do not block ads on this website.
Where does the word acid come from in chemistry?
Acid Definition in Chemistry. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution. The word acid comes from the Latin words acidus or acere, which mean “sour,” since one of the characteristics of acids in water is a sour taste (e.g., vinegar or lemon juice).
How to write equation for dilute hydrochloric acid?
Write the equation for this. You have to know that dilute hydrochloric acid is a solution of hydrogen chloride in water. For equation purposes, you can just write this as HCl. Obviously, you should know how to work this formula out but, to be honest, you will meet it so many times, that you will just know it.
