Answer:
\large \boxed{\text{150 g TiCl}_{4}}
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
Mᵣ: 189.68 79.87
TiCl₄ + 2H₂O ⟶ TiO₂ + 4HCl
m/g: 50.0
To solve this stoichiometry problem, you must
- Convert the actual yield to the theoretical yield
- Use the molar mass of TiO₂ to convert the theoretical yield of TiO₂ to moles of TiO₂
- Use the molar ratio to convert moles of TiO₂ to moles of TiCl₄
- Use the molar mass of TiCl₄ to convert moles of TiCl₄ to mass of TiCt₄
1. Theoretical yield of TiO₂
2. Moles of TiO₂
3, Moles of TiCl₄
The molar ratio is 1 mol TiO₂:1 mol TiCl₄.
4. Mass of TiCl₄
Answer: 1) endothernic
2) Yes absorbed
Explanation:
Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
