Here is a science problem from Chemistry:

Problem: Balance the following chemical equation:
$\text{CH}_4(\text{g}) + \text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + \text{H}_2\text{O}(\text{g})$

Count the atoms of each element on both sides of the equation.
Reactants:
C: 1
H: 4
O: 2

Products:
C: 1
H: 2
O: 3
Balance the Carbon (C) atoms.
The carbon atoms are already balanced (1 on each side).
Balance the Hydrogen (H) atoms.
There are 4 H atoms on the reactant side and 2 H atoms on the product side. To balance, place a coefficient of 2 in front of $\text{H}_2\text{O}$ on the product side:
$\text{CH}_4(\text{g}) + \text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{g})$
Re-count atoms and balance the Oxygen (O) atoms.
Reactants:
C: 1
H: 4
O: 2

Products:
C: 1
H: $2 \times 2 = 4$
O: $2 (\text{from } \text{CO}_2) + 2 (\text{from } 2\text{H}_2\text{O}) = 4$

Now, there are 2 O atoms on the reactant side and 4 O atoms on the product side. To balance, place a coefficient of 2 in front of $\text{O}_2$ on the reactant side:
$\text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{g})$
Verify that all atoms are balanced.
Reactants:
C: 1
H: 4
O: $2 \times 2 = 4$

Products:
C: 1
H: $2 \times 2 = 4$
O: $2 (\text{from } \text{CO}_2) + 2 (\text{from } 2\text{H}_2\text{O}) = 4$

All atoms are balanced.

The balanced chemical equation is:
$\boxed{\text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{g})}$
