"2HCl aq" refers to a chemical equation showing that two molecules of hydrochloric acid (HCl) are present in aqueous solution. This notation helps to indicate the stoichiometry of the reactants in a chemical reaction.
yes Zn + 2HCl -> ZnCl2 + H2 is balanced
Zn + 2HCl --- ZnCl2 + H2 Mg + 2HCl --- MgCl2 + H2
H2SO4+2NaCl=2HCl+Na2SO4
Zn + 2HCl -> ZnCl2 + H2 As you can see it is the hydrogen gas released in this reaction, which causes the effervescence. Just to note, in any reaction between a reactive metal and an acid, hydrogen gas is always produced.
In the chemical equation Zn + 2HCl ----> ZnCl2 + H2 the reactants are Zinc (Zn) and hydrochloric acid (HCl). The products are zinc chloride (ZnCl2) and Hydrogen (H2). The reactants are the compounds before the reaction arrow.
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
Zn(s) + 2HCl(aq) ---> ZnCl2(aq) + H2(gas)
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
The balanced chemical equation for the reaction between zinc and hydrochloric acid is: Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g).
When hydrochloric acid (HCl) reacts with zinc (Zn), it forms zinc chloride (ZnCl2) and hydrogen gas (H2) as products. The balanced chemical equation for this reaction is: 2HCl + Zn → ZnCl2 + H2
The balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen (H2) gas is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
When zinc reacts with hydrochloric acid (HCl), it undergoes a single displacement reaction to form zinc chloride (ZnCl2) and hydrogen gas (H2). The balanced chemical equation for this reaction is: Zn + 2HCl → ZnCl2 + H2.
Please see available answer, available at the link.
When hydrochloric acid (HCl) is reacted with zinc (Zn), it produces zinc chloride (ZnCl2) and hydrogen gas (H2). The chemical reaction can be represented as: 2HCl + Zn → ZnCl2 + H2. This reaction is a classic example of a single displacement reaction.
The correct balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is: Zn + 2HCl → ZnCl2 + H2 This reaction produces zinc chloride (ZnCl2) and hydrogen gas (H2).
To balance the equation Zn + HCl → ZnCl2 + H2, you need to ensure that the number of each type of atom is the same on both sides of the equation. To balance it, you would need to write it as Zn + 2HCl → ZnCl2 + H2. This equation balances the number of zinc, hydrogen, and chlorine atoms on both sides.
