k2so4+hno2
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
The reaction is the decomposition of potassium nitrate (KNO3) into potassium nitrite (KNO2) and oxygen (O2) gas. 2 KNO3 → 2 KNO2 + O2.
When methanol (CH3OH) reacts with sulfuric acid (H2SO4), it forms dimethyl ether (CH3OCH3) and water (H2O) as products. This reaction is known as the dehydration of methanol.
The reaction between sulfuric acid (H2SO4) and potassium hydroxide (KOH) will yield potassium sulfate (K2SO4) and water (H2O) as the products. This is a neutralization reaction where an acid reacts with a base to form a salt and water.
MgCl2 + H2SO4 ---> MgSO4 + 2HCl yield magnesium sulfate plus hydrogen chloride(gaz)
This is a decomposition reaction. KNO3 decomposes into KNO2 and O2 when heated.
When ferric oxide (Fe3O2) reacts with sulfuric acid (H2SO4), it forms ferric sulfate (Fe2(SO4)3) and water (H2O). The balanced equation for this reaction is: Fe3O2 + 3H2SO4 → 2Fe2(SO4)3 + 3H2O.
When aluminum oxide (Al2O3) is added to sulfuric acid (H2SO4), it typically reacts to form aluminum sulfate (Al2(SO4)3) and water (H2O). This is a common reaction in which the sulfuric acid breaks down the aluminum oxide to form the aluminum sulfate salt.
Na2CO3 + H2SO4 -> Na2SO4 + CO2 + H2O
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
The balanced equation for magnesium chloride (MgCl2) plus sulfuric acid (H2SO4) is: MgCl2 + H2SO4 → MgSO4 + 2HCl.
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
