Mg + H2CO3 = MgCO3 + H2
MgBr2 + F2 --> MgF2 + Br2 is a single replacement or single displacement reaction.
This is a decomposition reaction. KNO3 decomposes into KNO2 and O2 when heated.
Yes, the reaction between acetic acid (HC2H3O2) and sodium bicarbonate (NaHCO3) is indeed a double-displacement reaction. In this process, the acid and the bicarbonate exchange parts to form sodium acetate (NaC2H3O2) and carbonic acid (H2CO3). The carbonic acid is unstable and decomposes into water and carbon dioxide, which is often observed as bubbling or fizzing.
This is a single displacement reaction, specifically a redox reaction. In this reaction, iron displaces copper from copper sulfate to form iron sulfate and copper.
Na2O + H2O ---> 2NaOH this is a metal oxide (base) reacting with water to form an alkali
This is a double displacement reaction, where the sodium (Na) ion in NaHCO3 switches places with the hydrogen (H) ion in HC2H3O2 to form NaC2H3O2 and H2CO3.
This reaction is a single displacement reaction, also known as a displacement reaction or a replacement reaction. In this type of reaction, one element replaces another in a compound.
MgBr2 + F2 --> MgF2 + Br2 is a single replacement or single displacement reaction.
This is a decomposition reaction. KNO3 decomposes into KNO2 and O2 when heated.
This is a single displacement reaction, specifically a redox reaction. In this reaction, iron displaces copper from copper sulfate to form iron sulfate and copper.
The most usual reaction is Fe + PbSO4 => FeSO4 + Pb. This reaction can be called "displacement", "single displacement", or "electromotive displacement", and in all of the names previously given, "displacement" could be replaced by "replacement".
This is a single displacement reaction where fluorine displaces chlorine in calcium chloride to form calcium fluoride and chlorine gas.
Na2O + H2O ---> 2NaOH this is a metal oxide (base) reacting with water to form an alkali
A single-replacement reaction
2hcl
No, the reaction represented by KCl + HNO3 → KNO3 + HCl is a double replacement reaction where ions in the reactants exchange to form new compounds in the products. In a single displacement reaction, one element replaces another in a compound.
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
