I need help on this question.
Identify the mistakes in the following balanced equations. Rewrite the equation to make it correct. Each question has one mistake to correct.
a) C9H20+12O2 -> 9CO2 + 10H2O
b) H2+Cl -> 2HCl
To identify and correct the mistakes in the given balanced equations, we need to understand the process of balancing equations.
Balancing chemical equations involves ensuring that the number of atoms on both sides of the equation is equal. We need to adjust the coefficients (numbers in front of the chemical formulas) to achieve this balance.
Let's analyze the given equations to identify the mistakes and correct them:
a) C9H20 + 12O2 -> 9CO2 + 10H2O
Mistake: The coefficient for H2O is incorrect. It should be 19 instead of 10.
To correct the mistake, we need to adjust the coefficient to balance the number of oxygen atoms on both sides:
C9H20 + 12O2 -> 9CO2 + 19H2O
b) H2 + Cl -> 2HCl
Mistake: The coefficient for HCl is correct, but the number of hydrogen (H) atoms on the left side is incorrect. It should be 2 instead of 4.
To correct the mistake, we need to adjust the coefficient to balance the number of hydrogen atoms on both sides:
H2 + Cl2 -> 2HCl
By identifying the mistakes and making the necessary corrections, we have now balanced the equations:
a) C9H20 + 12O2 -> 9CO2 + 19H2O
b) H2 + Cl2 -> 2HCl
