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.
ZnS + H2SO4 ==>ZnSO4 + H2S
ZnSO4
Syntjesis
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.
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.
An increase in surface area means an increase in the rate of reaction.
Zn(s)-> Zn2+(aq)+2e- and Ni2+(aq) + 2e- ->Ni(s)
K + Zn --> K + Zn These two metals do not form a compound. There is no reaction.

Zn^2+ + 2e- ––> Zn(s)
It is a single displacement reaction. No balancing is needed in the resulting equation. Zn + CuBr2 ----> ZnBr2 + Cu
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.
An increase in surface area means an increase in the rate of reaction.
Zn(s)-> Zn2+(aq)+2e- and Ni2+(aq) + 2e- ->Ni(s)
K + Zn --> K + Zn These two metals do not form a compound. There is no reaction.
zinc (Zn), hydrogen (H) and chlorine (Cl) are the elements present.
The combination reaction of zinc metal plus sulfur solid produces zinc sulfide. This reaction occurs when zinc atoms react with sulfur atoms to form a compound. The balanced chemical equation for this reaction is: Zn (s) + S (s) → ZnS (s)
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
The reaction is: Zn + 2HCl = ZnCl2 + H2
Yes, according to the equation Zn (s) + 2HCl (aq) ----> ZnCl2 (aq) + H2 (g).
