Yes, a displacement reaction can surely be a redox reaction. Taking the example of chlorine and bromide ion. Chlorine oxidises a bromide ion making it bromine and bromide ion acts as a reducing agent forming chloride ion at the end of the experiment.
double replacement reactions are never redox
Yes it can. I believe that an example of such a reaction would be the addition of zinc to a solution of 6 molar hydrochloric acid (HCl).
Double replacement reactions are always non-redox
Yes, it can be.
Example:
Fe + CuSO4 ----------> FeSO4 + Cu
Here Fe is oxidized to Fe2+ and Cu2+ is reduced to Cu.
no, only single displacement can
A double-displacement reaction is characterized by the fact that bonds of the reactants are changed.
No, it is a single displacement reaction. It can also be called a redox reaction. It is not an acid base reaction because although hydrochloric acid is obviously and acid, magnesium is a metal, not a base.
It is a double replacement reaction, also called a double displacement reaction.
a displacement reaction, magnesium displaces hydrogen because it is more reactive
2Mg + O2------> 2MgO

It is a double replacement reaction, also called a double displacement reaction.
I think you mean metal + water = metal hydroxide + hydrogen. This is a displacement reaction. It can also be called a redox reaction.
2Mg + O2------> 2MgO

A chemical reaction in which two elements or radicals change places with two other elements is called double replacement. It is also known as double displacement. Its general pattern can be written as AB + CD --> AD + CB
another name for an exchange reaction but metathesis reaction. This reaction usually occurs in hydrolysis and is AB+CD=AD+CB
When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
No, it is a double replacement reaction. Photosynthesis is not a single reaction pathway but two, one dependent on the other. Therefore, your answer is photosynthesis is a double replacement reaction. The chemical equation for photosynthesis is: 6CO2 + 6H2O --> C6H12O6 + 6O2 Also, since you start AND end with two compounds, that also makes it a double replacement reaction.
combustion and single-replacement
This redox reaction also requires an acid as H2SO4 , the overall reaction is.... 5H2C2O4 + 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 10CO2 +8H2O
