The Unbalanced Equation For The Reaction Between Methane And Bromine Is:$\[ CH_4(g) + \ldots Br_2(g) \rightarrow \ldots CBr_4(s) + \ldots HBr(g) \\]Once This Equation Is Balanced, What Is The Value Of The Coefficient In Front Of Bromine
Understanding the Unbalanced Equation
The unbalanced equation for the reaction between methane and bromine is:
This equation represents the reaction between methane (CH4) and bromine (Br2) to form carbon tetrabromide (CBr4) and hydrogen bromide (HBr). However, the equation is not balanced, meaning that the number of atoms of each element on the reactant side does not equal the number of atoms of each element on the product side.
Balancing the Equation
To balance the equation, we need to add coefficients in front of the formulas of the reactants and products. The goal is to make sure that the number of atoms of each element is the same on both sides of the equation.
Let's start by counting the number of atoms of each element on both sides of the equation:
Reactant side:
- C: 1
- H: 4
- Br: 2
Product side:
- C: 1
- H: 1
- Br: 4
As we can see, the number of atoms of each element is not the same on both sides of the equation. To balance the equation, we need to add coefficients in front of the formulas of the reactants and products.
Adding Coefficients
To balance the equation, we need to add coefficients in front of the formulas of the reactants and products. Let's start by adding a coefficient in front of the formula of bromine (Br2).
Since there are 4 bromine atoms on the product side, we need to add a coefficient of 2 in front of the formula of bromine (Br2) to make sure that the number of bromine atoms on the reactant side is equal to the number of bromine atoms on the product side.
The updated equation is:
Balancing the Carbon Atoms
Now that we have added a coefficient in front of the formula of bromine (Br2), we need to balance the carbon atoms. Since there is 1 carbon atom on the product side, we need to add a coefficient of 1 in front of the formula of carbon tetrabromide (CBr4) to make sure that the number of carbon atoms on the reactant side is equal to the number of carbon atoms on the product side.
The updated equation is:
Balancing the Hydrogen Atoms
Now that we have balanced the carbon atoms, we need to balance the hydrogen atoms. Since there are 4 hydrogen atoms on the reactant side, we need to add a coefficient of 4 in front of the formula of hydrogen bromide (HBr) to make sure that the number of hydrogen atoms on the reactant side is equal to the number of hydrogen atoms on the product side.
The updated equation is:
The Final Balanced Equation
The final balanced equation for the reaction between methane and bromine is:
Conclusion
In conclusion, the unbalanced equation for the reaction between methane and bromine is:
Once this equation is balanced, the value of the coefficient in front of bromine is 2.
Importance of Balancing Chemical Equations
Balancing chemical equations is an important step in chemistry. It helps us to understand the stoichiometry of a reaction, which is the ratio of reactants to products. Balancing chemical equations also helps us to predict the yield of a reaction, which is the amount of product formed.
Common Mistakes in Balancing Chemical Equations
There are several common mistakes that people make when balancing chemical equations. One of the most common mistakes is to add coefficients in front of the formulas of the reactants and products without making sure that the number of atoms of each element is the same on both sides of the equation.
Another common mistake is to add coefficients in front of the formulas of the reactants and products without making sure that the equation is still balanced.
Tips for Balancing Chemical Equations
Here are some tips for balancing chemical equations:
- Start by counting the number of atoms of each element on both sides of the equation.
- Add coefficients in front of the formulas of the reactants and products to make sure that the number of atoms of each element is the same on both sides of the equation.
- Make sure that the equation is still balanced after adding coefficients in front of the formulas of the reactants and products.
- Use a systematic approach to balance the equation, such as balancing the atoms of one element at a time.
