Answer:
When acetylene reacts with silver nitrate, its acidic hydrogen reacts with silver nitrate to form a white precipitate. So here acetylene shows its acidic nature.
Explanation:
this is what i found
Mass = 70.5 grams
D = m/v
D=4.7 g/mL
V=15mL
4.7=m/15
4.7=1/15m
M=70.5g
Answer:
They all wear their skeletons on the outside! This is called an exoskeleton and all creatures that have their structure on the outside are included in the phylum of Arthropods.
Explanation:
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.
