Question

Доповніть схеми реакцій та доберіть коефіцієнти.: а) Li2O + H2O → ……; б) SO3 + H2O → ……; в) …… + H2O → Ba(OH)2 г) C3H8 + O2 → CO2 + H2O помогите пожалуйста

Answer 1

Ответ:

а) Li2O + H2O → 2LiOH

б) SO3 + H2O → H2SO4

в)BaO + H2O → Ba(OH)2

г) C3H8 + O2 → 3CO2 + 4H2O

Answer 2

а) Li2O + H2O → ?

The reaction between lithium oxide (Li2O) and water (H2O) can be represented as follows:

Li2O + H2O → 2LiOH

In this reaction, lithium oxide reacts with water to form lithium hydroxide (LiOH). The balanced equation shows that two moles of lithium oxide react with one mole of water to produce two moles of lithium hydroxide.

б) SO3 + H2O → ?

The reaction between sulfur trioxide (SO3) and water (H2O) can be represented as follows:

SO3 + H2O → H2SO4

In this reaction, sulfur trioxide reacts with water to form sulfuric acid (H2SO4). The balanced equation shows that one mole of sulfur trioxide reacts with one mole of water to produce one mole of sulfuric acid.

в) ? + H2O → Ba(OH)2

To complete the reaction and balance the equation, we need to determine the reactant that will produce barium hydroxide (Ba(OH)2) when it reacts with water (H2O). One possible reactant is barium oxide (BaO):

BaO + H2O → Ba(OH)2

In this reaction, barium oxide reacts with water to form barium hydroxide. The balanced equation shows that one mole of barium oxide reacts with one mole of water to produce one mole of barium hydroxide.

г) C3H8 + O2 → ?

The reaction between propane (C3H8) and oxygen (O2) can be represented as follows:

C3H8 + 5O2 → 3CO2 + 4H2O

In this reaction, propane reacts with oxygen to produce carbon dioxide (CO2) and water (H2O). The balanced equation shows that one mole of propane reacts with five moles of oxygen to produce three moles of carbon dioxide and four moles of water.
