Answer 1

Na2SiO2 + H2SO4 = Na2SO4 + H2SiO2(нераствор.) - обмен
3H2SO4 + 2Al =(с нагреванием) Al2(SO4)3 + 3H2 (Выделение газа) - замещение
2SO2 + O2 = 2SO3 - соединение

Answer 2

Equation 1: Silicate Sodium + Sulfuric Acid = Sodium Sulfate + Silicic Acid

The balanced equation for the reaction between silicate sodium and sulfuric acid is as follows:

Na2SiO3 + H2SO4 → Na2SO4 + H2SiO3

This is a double displacement reaction, also known as a metathesis reaction, where the positive ions of two compounds switch places.

Equation 2: Sulfuric Acid + Aluminum = Aluminum Sulfate + Hydrogen

The balanced equation for the reaction between sulfuric acid and aluminum is as follows:

H2SO4 + 2Al → Al2(SO4)3 + H2

This is a single displacement reaction, where the aluminum replaces the hydrogen in the sulfuric acid to form aluminum sulfate and hydrogen gas.

Equation 3: Sulfur Dioxide + Oxygen = Sulfur Trioxide

The balanced equation for the reaction between sulfur dioxide and oxygen is as follows:

2SO2 + O2 → 2SO3

This is a synthesis reaction, where two substances combine to form a single compound.

Please note that the equations provided are balanced equations, meaning that the number of atoms of each element is the same on both sides of the equation.
