This chemical reaction is balanced True False
1C2H5OH + 2O2 → 2CO2 + 3H2O
True
True, the chemical reaction is balanced.
To determine whether the given chemical reaction is balanced or not, we need to check if the number of atoms of each element is the same on both sides of the equation.
In the given reaction:
1C2H5OH + 2O2 → 2CO2 + 3H2O
Let's break it down and count the number of atoms for each element on both sides.
On the left side:
Carbon (C): 1
Hydrogen (H): 2 x 5 = 10
Oxygen (O): 2
On the right side:
Carbon (C): 2
Hydrogen (H): 3 x 2 = 6
Oxygen (O): 2 x 2 = 4
As we can see, the number of atoms for each element is not the same on both sides of the equation. Therefore, the given chemical reaction is not balanced.
To balance the equation, we need to adjust the coefficients in front of each compound so that the number of atoms for each element is equal on both sides. In this case, we can balance the equation by multiplying C2H5OH by 2 and H2O by 3:
2C2H5OH + 2O2 → 4CO2 + 6H2O
Now, if we count the number of atoms for each element, it becomes balanced:
Carbon (C): 2 x 2 = 4
Hydrogen (H): 6 x 2 = 12
Oxygen (O): 2 x 2 = 4
So, the balanced chemical reaction is:
2C2H5OH + 2O2 → 4CO2 + 6H2O
The correct answer is False.
