To make this equation right, coefficients must be added in front of molecules, so number of atoms in right and left are equal.
2O₂ + CH₄ = CO₂ + 2H₂O
How, you have 4 atoms of oxygen,1 atom of carbon and 4 atoms of hydrogen on both side of reaction.
Answer:
The open system evaporates the solvent in the solution
Explanation:
An open system is a system in which exchange of materials and energy can occur. If a TLC set up is left open, then the set up constitutes an open system.
During TLC, the sample is dotted on the plate and inserted into a suitable solvent. The solvent moves up the plate and achieves the required separation of the mixture.
Most of these solvents used used TLC are volatile organic compounds. Therefore, if the TLC set up is left open, the solvent will evaporate leading to poor results after running the TLC experiment.
