Answer:
Two
Explanation:
In a double-replacement reaction, there will be two reactants and two products.
It is called double replacement reaction because one element in reactant 1 replaces an element in reactant 2 and other element in reactant 2 replaces other element in reactant 1.
Here two replacements are taking place. Hence, this is called double replacement reaction.
A Neutralization reaction i.e an Acid - Base reaction is a good example of Double replacement reaction.
An Example is provided below for better understanding :
HNO3 + NaOH --> NaNO₃ + H₂O.
Here HNO₃ is the acid and NaOH is the base which are the reactants.
NaNO₃ and H₂O are the products.
This is a double replacement reaction because,
Hydrogen(H) in HNO₃ replaces Sodium(Na) in NaOH, and
NO₃ in HNO₃ replaces OH in NaOH.
Here, there are 2 reactants and 2 products.
I think that it’s A i have done a test on this before so I think it’s A
