2koh + h2so4 = k2so4 + 2h20
The reaction between selenium dioxide and aqueous potassium hydroxide forms selenites, or salts containing the SeO3^2- ion, and water. This reaction can be represented as SeO2 + 2KOH + H2O β K2SeO3 + H2O.
The answer is one mole.

No Potassium oxide is extremely basic (alkaline).
In the reaction CuSO4 + 2KOH, copper sulfate reacts with potassium hydroxide to form copper(II) hydroxide (Cu(OH)2) and potassium sulfate (K2SO4). The state of each compound can be written as follows: CuSO4 (aq) + 2KOH (aq) β Cu(OH)2 (s) + K2SO4 (aq) Here, the reactants (CuSO4 and KOH) are in aqueous solution, while the products (Cu(OH)2 and K2SO4) are in solid and aqueous states, respectively.
The balanced equation for the reaction between lithium hydroxide (LiOH) and potassium chloride (KCl) is: 2LiOH + KCl β Li2O + 2KOH
The single replacement reaction for potassium and water can be represented as: 2K(s) + 2H2O(l) -> 2KOH(aq) + H2(g)
The formation equation for potassium sulfite (K2SO3) is: 2KOH + SO2 -> K2SO3 + H2O
Your balanced chemical equation for this double replacement reaction would be: Cu(NO3)2 + 2KOH ----> Cu(OH)2 + 2KNO3 Therefore, you would end up with copper II hydroxide and potassium nitrate.
This is a chemical equation representing the reaction of potassium with water to form potassium hydroxide and hydrogen gas: 2K + 2HβO β 2KOH + Hβ. To balance it, simply ensure that the number of atoms of each element is the same on both sides of the equation. In this case, the equation is already balanced.
2koh + h2so4 = k2so4 + 2h20
K2SO4 + 2NaOH ==> Na2SO4 + 2KOH
The equation for the reaction between potassium chromate (K2CrO4) and copper sulfate (CuSO4) is: 2K2CrO4 + 3CuSO4 -> 2Cr2(SO4)3 + 3CuCrO4(s) This reaction produces chromium(III) sulfate and copper chromate as the products.
The net ionic equation for the reaction between 2KOH and H2SO4 to form K2SO4 and water is: 2OH- + 2H+ -> 2H2O
When you mix copper sulfate and potassium hydroxide, a blue precipitate called copper hydroxide is formed. This is due to the reaction between copper ions from copper sulfate and hydroxide ions from potassium hydroxide. The chemical equation for this reaction is CuSO4 + 2KOH β Cu(OH)2 + K2SO4.
