Объяснение:

Answer 2

A. NaOH + H2SO4 =

The balanced equation for the reaction between sodium hydroxide (NaOH) and sulfuric acid (H2SO4) is:

2NaOH + H2SO4 = Na2SO4 + 2H2O [[1]]

B. MgO + HNO3 =

The balanced equation for the reaction between magnesium oxide (MgO) and nitric acid (HNO3) is:

MgO + 2HNO3 = Mg(NO3)2 + H2O [[2]]

C. KOH + CuCl2 =

The balanced equation for the reaction between potassium hydroxide (KOH) and copper(II) chloride (CuCl2) is:

2KOH + CuCl2 = 2KCl + Cu(OH)2 [[3]]

D. KCl + AgNO3 =

The balanced equation for the reaction between potassium chloride (KCl) and silver nitrate (AgNO3) is:

KCl + AgNO3 = AgCl + KNO3 [[4]]

Please note that the above equations are balanced and represent the stoichiometry of the reactions.
