Question

H2SO4+NaOH=H2SO4+Mg=H2SO4+Na2SO3=SO3+MgO=SO3+H2O=

Answer 1

H2SO4+NaOH = NaSO4+ H2O ( кислота + основание= соль+вода)

H2SO4+Mg = MgSO4 + H2 ( кислота + металл = соль + водород)

H2SO4+Na2SO3 = Na2SO4 + H2SO3( кислота + соль= слабая кислота + новая соль )

SO3+MgO = MgSO4 (кислотный оксид + основной оксид = соль)

SO3 + H2O = H2SO4 (кислотный оксид + вода = кислота )

Answer 2

Balancing Chemical Equations

Let's balance the chemical equations you provided step by step:

1. H2SO4 + NaOH = H2SO4 + Mg

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

H2SO4 + 2NaOH = Na2SO4 + 2H2O + Mg.

2. H2SO4 + Na2SO3 = SO3 + MgO

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

H2SO4 + Na2SO3 = SO3 + H2O + MgO.

3. SO3 + MgO = SO3 + H2O

This equation is already balanced. The balanced equation is:

SO3 + MgO = SO3 + H2O.

4. SO3 + H2O = H2SO4

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

SO3 + H2O = H2SO4.
