Answer:
identify the atoms on each side.
Count the atoms on each side.
Use coefficients to increase the atoms on each side.
Check to make sure you have the same number of each type of atom on each side.
Explanation:
The concept behind balancing chemical equations is to ensure that they comply with the law of conservation of matter. This helps to make chemical equations quantitatively meaningful.
- First, identify the atoms on each side of the expression.
- Then count these atoms.
- Assign appropriate numeric coefficient to the species.
- Then check to make sure there are equal number of each type of atoms on each side.
The subscript of the formula must not be changed in an attempt to balance a chemical equation.
Over here you have to use the formula: <span>P1/T1= P2/T2
P1= 7.58
T1= 639
P2= ?
T2= 311
</span><span>7.58/639 = ?/311
</span>= 3.689 kPa
