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.
It has a high percentage of germination in pH’s 13-14 this shows that radish seeds can germinate very well in almost all pH levels
Answer:
Measuring the Volume of Solids
Rectangular prism - Multiply the measurement of the length times the width, then times the height.
Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³
Explanation:
Answer:
The answer is the angle made by a refracted ray with a perpendicular to the refracting surface.
Explanation:
- <u><em>A prism uses refraction to form a spectrum of colors from an incident beam of light.</em></u>
