Write a balanced chemical equation for the reaction that occurs when (a) titanium metal reacts with O21g2
Guida verificata passo dopo passo1
Step 1: Identify the reactants and the products. In this case, the reactants are titanium (Ti) and oxygen (O2). The product is titanium dioxide (TiO2), which is the compound formed when titanium reacts with oxygen.
Step 2: Write the unbalanced chemical equation. This is done by writing the reactants on the left side of the equation and the products on the right side. The equation would look like this: Ti + O2 -> TiO2
Step 3: Balance the chemical equation. This is done by adjusting the coefficients (the numbers in front of the reactants and products) until the number of atoms of each element is the same on both sides of the equation. In this case, the balanced equation would be: 2Ti + O2 -> 2TiO2
Step 4: Check your work. Count the number of atoms of each element on both sides of the equation to make sure they are equal. In this case, there are 2 titanium atoms and 2 oxygen atoms on both sides of the equation, so the equation is balanced.
Step 5: Write the final balanced chemical equation: 2Ti + O2 -> 2TiO2

Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Balanced Chemical Equation
A balanced chemical equation represents a chemical reaction where the number of atoms for each element is the same on both the reactant and product sides. This is crucial for obeying the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing involves adjusting coefficients in front of compounds to ensure equal atom counts.

Balancing Chemical Equations
Reactants and Products
In a chemical reaction, reactants are the starting substances that undergo change, while products are the substances formed as a result of the reaction. Identifying the correct reactants and products is essential for writing a balanced equation. In this case, titanium (Ti) is the reactant, and the product will be titanium oxide formed from its reaction with oxygen (O2).

Stoichiometry
Stoichiometry is the area of chemistry that deals with the quantitative relationships between the amounts of reactants and products in a chemical reaction. It allows chemists to predict how much of each substance is involved in the reaction. Understanding stoichiometry is vital for balancing equations, as it helps determine the correct coefficients needed to represent the reaction accurately.
