Neutralization reaction.
2HCl + Ca(OH)2 ==> CaCl2 + 2H2O
This is NOT an oxidation-reduction reaction.
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
Zn alone is a reducing agent because it donates electrons during a reaction and H2SO4 alone is an oxidizing agent because it may donates atomic oxygen during the reaction but (Zn + H2SO4) mixture is a reducing agent because this mixture may produce atomic hydrogen during a reaction.
In this reaction, FeCl2 is the oxidizing agent because it causes another species to be reduced (lose electrons), while SnCl2 is the reducing agent because it causes another species to be oxidized (gain electrons).
The balanced equation for magnesium chloride (MgCl2) plus sulfuric acid (H2SO4) is: MgCl2 + H2SO4 → MgSO4 + 2HCl.
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
The ferrous oxide is the oxdant.
The oxidizing agent in the reaction CH4 + 2O2 → CO2 + 2H2O is oxygen (O2). Oxygen is the substance that is gaining electrons and causing the methane (CH4) to oxidize.
In the reaction Zn + CuCl2 → ZnCl2 + Cu, CuCl2 is the oxidizing agent because it accepts electrons from Zn, causing zinc to be oxidized and copper to be reduced.CuCl2 itself gets reduced to Cu.
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
water [H20]
Zn(s) + 2HCl(aq) ---> ZnCl2(aq) + H2(gas)
CaO+2H2CL2O
CaO+2H2CL2O
Zn alone is a reducing agent because it donates electrons during a reaction and H2SO4 alone is an oxidizing agent because it may donates atomic oxygen during the reaction but (Zn + H2SO4) mixture is a reducing agent because this mixture may produce atomic hydrogen during a reaction.
CuO + 2HCL - CuCl2 + H2O
Probably as a Displacement reaction
