<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:
The correct name is 5-chloro-2-pentyne.
Explanation:
- <em>Kindly see the attached image.</em>
- It summarizes the rules of IUPAC system to name the compounds.
- We have 5 carbon atoms that take the name (pent).
- The carbon skeleton should be numbered that the position of the triple bond should have the lowest number in the skeleton, so the triple bond is between C2 and C3.
- It takes the lowest number (2) and added (yne) at the end of the name.
- (yne) is express the presence of triple bond.
- The (Cl) atom take the number 5.
- <em>So, the correct name of the compound is 5-chloro-2-pentyne.</em>

Answer: The theoretical yield and percent yield for this experiment are 40 g and 82% respectively.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.
To calculate the moles:
According to stochiometry:
2 moles of produce = 2 moles of
0.54 moles of should produce = of
Thus theoretical yield is
But Experimental yield is 33 g.
The theoretical yield and percent yield for this experiment are 40 g and 82% respectively.
Answer:
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. ... According to Dalton, atoms of different elements combine in simple whole number ratios to form compounds.
