Molecular equation:
A molecular equation:
Molecular equations shows the molecular formula of compounds or moleucles of elements of all reactants and products.
AlCl₃ + Na₂CO₃
→ NaCl
+ Al₂(CO₃)₃
Balanced equation : 2AlCl₃ + 3Na₂CO₃ → 6NaCl + Al₂(CO₃)₃
Ionic equation:
Water soluble reactants and products splits into their constituent ions while non-ionizing or gaseous reactants and products are represented by formulae or molecules.
2Al³⁺ + 6Cl⁻
+ 6Na⁺
+ 2CO₃²⁻
→ 6Na⁺
+ 6Cl⁻
+ Al₂(CO₃)₃
Net ionic equation:
Ions that are non-reactive are called spectator ions, they are cancelled out to give the net ionic equation.
2Al³⁺ + 6Cl⁻
→ Al₂(CO₃)₃

Answer:
The boiling and freezing temperatures of krypton at absolute scale are 119.95 K and 116.05 K, respectively.
Explanation:
The absolute temperature on SI units corresponds to Kelvin scale, whose conversion formula in terms of the Celsius scale is:
Where:
- Absolute temperature, measured in Kelvins.
- Relative temperature, measured in Celsius.
Finally, freezing and boiling temperatures are converted into absolute scale:
Boiling temperature
Freezing temperature
The boiling and freezing temperatures of krypton at absolute scale are 119.95 K and 116.05 K, respectively.
