2ZnS + 3O2 ---> 2ZnO + 2SO2 Zinc sulphide + Oxygen ---> Zinc oxide + Sulphur dioxide This reaction is endothermic and requires a heat change (H) in order to happen. As the Zinc sulphide reacts with the oxygen the zinc becomes oxidised (oxidation, zinc atoms bond to oxygen atoms), and during this reaction sulphur dioxide is given off.
What else can I help you with?
Is oxidation reaction a single replacement reaction?
It can be, but it can also be other types of reaction. An example of an oxidation reaction that is also a single replacement would be Zn(s) + 2HCl ==> ZnCl2 + H2. In this reaction Zn is oxidized and H is reduced.
Half-cell reactions when metallic zinc is dipped into a solution of copper sulphate?
In this case, zinc will undergo oxidation and copper ions will experience reduction. The reduction half-reaction is Cu^2+ (aq) + 2e^- → Cu (s), and the oxidation half-reaction is Zn (s) → Zn^2+ (aq) + 2e^-. Overall, the reaction is Zn (s) + Cu^2+ (aq) → Zn^2+ (aq) + Cu (s).
Classify each what reactions as combination decomposition displacement or double displacement reaction Zn s plus 2AgNO3 aq ---- Zn NO3 2 plus 2Ag s?
Zn(s) + 2AgNO3(aq) --> Zn(NO3)2(aq) + 2Ag(s) is a single displacement reaction. It is also called a single replacement reaction. As you can see, the zinc displaced, or replaced, the silver in the silver nitrate solution.
As the surface area of the Zn(s) used in the reaction Zn(s) + 2HCl(aq)--> ZnCl2(aq) + H2(g) is increased, the rate of the reaction willIncreaseDecreaseRemain the Same?
An increase in surface area means an increase in the rate of reaction.

Zn(s)-> Zn2+(aq)+2e- and Ni2+(aq) + 2e- ->Ni(s)
What is the reduction half-reaction for Mg(s) ZnCI2(aq)MgCI2(aq) Zn(s)?
The reduction half-reaction for this reaction is: Zn^2+ + 2e- -> Zn(s).
Is oxidation reaction a single replacement reaction?
It can be, but it can also be other types of reaction. An example of an oxidation reaction that is also a single replacement would be Zn(s) + 2HCl ==> ZnCl2 + H2. In this reaction Zn is oxidized and H is reduced.
What coefficient does Zn s have in the balanced equation?
In the balanced equation for the reaction involving solid zinc (Zn(s)), the coefficient for Zn(s) is 1. This means that 1 mole of solid zinc is consumed or produced in the reaction.

What is the reduction half-reaction for Mgs ZnCl2aq MgCl2aq Zns?
Zn^2+ + 2e- ––> Zn(s)
Chemical reaction of HCl on Zinc?
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.
What is the balance equation for Zn plus CuBr2?
The balanced equation for the reaction between zinc (Zn) and copper (II) bromide (CuBr2) is: Zn + CuBr2 → ZnBr2 + Cu
