<h2>Answer with Explanation </h2>
Chromatography is utilized to isolate blends of substances into their segments. All types of chromatography chip away at a similar guideline. They all have a stationary stage (a strong, or a fluid bolstered on a strong) and a portable stage (a fluid or a gas). A paper chromatogram can likewise be utilized to recognize substances by contrasting them and known substances. Two substances are probably going to be the equivalent in the event that:
- they deliver a similar number of spots and these match in shading.
The spots venture to every part of a similar separation up the paper (have a similar R f esteem). Rƒ esteem, solutes, and solvents. The maintenance factor (Rƒ) might be characterized as the proportion of the separation ventured out by the solute to the separation gone by the dissolvable. It is utilized in chromatography to measure the measure of the hindrance of an example in a stationary stage in respect to a portable stage.
Answer: hello the experiment related to your question is missing but I will provide a more general answer within the scope of your question
answer :
presence of Impurities
Explanation:
The melting point of the crystals as obtained in the experiment will be close to but below reference melting points and will also melt slower because of the presence of impurities in the compound
Impurities alter the melting and freezing points from ideal freezing and melting points of compounds
Answer: Option (c) is the correct answer.
Explanation:
Energy that is acquired by the molecules of a substance due to their motion is known as kinetic energy.
For example, when we heat water in excess then it starts to boil and it changes into vapors.
Hence, when molecules of a liquid gain kinetic energy then they start to collide rapidly with each other. As a result, molecules move away from each other and there occurs decrease in force of attraction between the molecules. This leads to change of liquid state into vapor or gaseous state.
Thus, we can conclude that the statement they move fast enough to overcome the forces of attraction that hold them together, becoming a gas, best explains what happens when the kinetic energy of particles in a liquid state increases.
Answer:
hi sorry I need the points to ask a question myself please dont delete this until I say I asked my question cus if u do it before it will remove the, thanks bye.
Explanation:
thx, and sorry if I sound rude its just I REALLY need the points. (sorry for the caps)
Answer:
The correct answer is - 1. oxaloacetate.
Explanation:
During the electron transport chain, the oxaloacetate is converted to aspartate by the reduction of NADH and accepting electrons in the mitochondria. Aspartate is then moved through the inner membrane to the cytosol.
This is the reaction also known as the synthesis of the aspartate. Aspartate either again converted to OAA (oxaloacetate) or move to the biosynthesis of proteins and biosynthesis of purine and pyrimidines.
