This is a synthesis reaction.
The reactants of the reaction between H2 and N2 to form NH3 are hydrogen gas (H2) and nitrogen gas (N2).
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
The single replacement reaction for calcium and hydrochloric acid is: Ca + 2HCl -> CaCl2 + H2
The reaction between copper (Cu) and hydrochloric acid (HCl) to form copper(II) chloride (CuCl2) and hydrogen gas (H2) is a single displacement reaction. This is because the copper replaces the hydrogen in HCl to form CuCl2.
single replacement
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
In this reaction, zinc (Zn) reacts with sulfuric acid (H2SO4) to form zinc sulfate (ZnSO4) and hydrogen gas (H2). This is a single displacement reaction where zinc replaces hydrogen in sulfuric acid to form zinc sulfate and release hydrogen gas.
The single replacement reaction between iron (Fe) and C2H3O2 would form iron acetate (Fe(C2H3O2)3) and hydrogen gas (H2) as a product. This reaction occurs because iron is more reactive than hydrogen and replaces it in the acetate compound.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
The single replacement reaction for potassium and water can be represented as: 2K(s) + 2H2O(l) -> 2KOH(aq) + H2(g)
Displacement reaction , as HCl displaces S of FeS to give H2S
Mg + H2CO3 = MgCO3 + H2
