Consider the equation:
CH4+O2→2H2O+CO2
Which element or elements are unbalanced in this equation?
A- Both H and O are unbalanced.
B- C, H, and O are all unbalanced.
C- Only the O is unbalanced.
D- Only the H is unbalanced.
you try
how many C on the left, how many C on the right?
How many H on the left, how many H on the right?
How many O on the left, how many O on the right?
(Only one of them is messed up)
its c only o is unbalanced
You look at each side to see. To be balanced there must the the same number of each kind of atom on each side. For example, I see one atom of C on each side so that's balanced.
To determine which element or elements are unbalanced in the equation CH4 + O2 → 2H2O + CO2, we need to compare the number of atoms of each element on both sides of the equation.
On the left side:
- Carbon (C) has 1 atom.
- Hydrogen (H) has 4 atoms.
- Oxygen (O) has 2 atoms.
On the right side:
- Hydrogen (H) has 4 atoms.
- Oxygen (O) has 3 + 1 (from CO2) = 4 atoms.
From the comparison, it is clear that the number of hydrogen atoms is balanced (4 on both sides), but the number of oxygen atoms is not balanced (2 on the left, 4 on the right). Therefore, the correct answer is:
C- Only the O is unbalanced.
