What will the effect be on the resolution and Rf values in the following situations? (paper chromatography experiment)

a) The watch glass is left off the beaker during the run
b) The chromatogram was left in the beaker too long so that the solvent front went all the way to the top of the paper in 5 minutes before the paper was removed
c) The spots were too big
d) A student used a shorter piece of chromatographic paper

Answers

Chromatography is primarily used as a method for the analysis and separation of chemical mixtures. Chromatography is the process of causing the constituent parts of a mixture to migrate differently from a restricted starting point in a particular medium, in this case, filter paper.

A) The air pressure above the beaker would disrupt the flow of the spots through the TLC, resulting in less resolution on the TLC plate, if the watch glass is not kept above the beaker for running paper chromatography. Despots would look, and even swarm, as a result.

B) The solvent is not allowed to move completely through the TLC plate because if the chromatogram is left in the beaker for a long time so that the solvent completely flows to the top, all of the spots would reach the solvent front and we would be unable to distinguish between the spots present in the TLC plate.

C). The TLC spotting should be performed in a very minute manner. Assume that if this substance is quite thick and a few of spots are seen apart, the TLC plate would drag and the resolution would be thrown off. As a result, it is challenging to tell the spots apart.

D). If the chromatographic paper is very short, it will be difficult to distinguish between the spots because, if more than one spot is present in a given compound, it will be harder to determine how many spots there are if there is a smaller distance between them. The TLC sheet's shorter length is the cause of the decreased space between the supports. Therefore, it is preferable to avoid using this longer TLC sheet so that the resolution is high and the spots can be easily identified.

Answers

The volume of 0.175 M [tex]Na_3PO_4[/tex] solution required to completely react with 126 mL, 0.150 M  [tex]CuCl_2[/tex] is 0.72 L 0r 720 mL.

Stoichiometric problem

From the balanced equation of the reaction, the mole ratio of  [tex]Na_3PO_4[/tex] and   [tex]CuCl_2[/tex] is 2:3.

Recall that: mole = molarity x volume

126 mL = 126/1000 = 0.126 L

Mole of 126 mL, 0.150 M   [tex]CuCl_2[/tex] = 0.150 x 0.126

                = 0.0189 moles

Equivalent mole of  [tex]Na_3PO_4[/tex] from the mole ratio = 2/3 x 0.0189

                   = 0.0126 moles

Volume = mole/molarity

Volume of 0.0126 moles, 0.175 M  [tex]Na_3PO_4[/tex] = 0.126/0.175

               = 0.72 L

0.72 L = 0.72 x 1000

             = 720 mL

In other words, 0.72 L 0r 720 mL of 0.175 M [tex]Na_3PO_4[/tex] is required to completely react with 126 mL of 0.150 M  [tex]CuCl_2[/tex].

a sample of solid chromium is heated with an electrical coil. if 110 joules of energy are added to a 14.2 gram sample initially at 20.7 °c, what is the final temperature of the chromium?

Answers

If 110j of energy are added to a 14.2 gram sample initially at 20.7 °c . the final temperature will be 36.89°C.

Given,

mass of chromium = m = 14.2g

initial temperature = T1 = 20.7°C

Q = m X C X ∆T

where,

Heat exchanged at Q

m = the sample's mass

C = sample specific heat, which for chromium is 0.460 J/goC.

Temperature change (T) = Tfinal - Tinitial.

So, We know,

106J = 13.8 X 0.460J/g°C X (Tfinal - 20.2°C )

(Tfinal - 20.2oC ) = 106J / 13.8 X 0.460J/g°C = 16.69

Tfinal = 16.69°C + 20.2°C = 36.89°C

Hence, The final temperature will be 36.89°C.

List two differences and two similarities between a recipe for baking a cake and a chemical reaction.

Answers

The main difference between a recipe for baking a cake and a chemical reaction is that baking a cake is a chemical change whereas a chemical reaction may be a chemical and physical change.

The similarities between a recipe for baking a cake and a chemical reaction is that the molecules react with each other and in both new substances are formed at the end.

How is baking a cake similar to a chemical reaction?

When you bake a cake, the ingredients pass through a chemical change. A chemical change occurs when the molecules are rearranged to form a new substance. When you start baking, you have many ingredients. Baking a cake is a chemical change because the ingredients rearrange to form a new substance which is not reversed. The sugar, flour, and eggs can't be separated from each other. The properties of the materials have changed so it is considered as a chemical change.

So we can conclude that baking a cake and a chemical reaction is different due to the presence of chemical change whereas chemical reactions have both chemical and physical change.

The heat needed to change 9.8 grams of solid ammonia at -75 degrees C into a gas at room temperature 25 degrees C is 231 kJ.

What is solid ammonia?
With the formula NH₃, ammonia is a nitrogen and hydrogen inorganic chemical. Ammonia, the simplest pnictogen hydride and a stable binary hydride, is a colourless gas with a strong, pungent odour. It contributes considerably to the nutritional demands of terrestrial creatures by serving as a precursor to 45 percent of the world's food and fertilisers. Biologically, it is a common nitrogenous waste, especially among aquatic animals. About 70% of ammonia is used to create fertilisers, including urea and diammonium phosphate, in a variety of shapes and compositions. Additionally, pure ammonia is sprayed straight onto the ground. Ammonia is also a key ingredient in many commercial cleaning solutions and is a building component for the manufacture of numerous medicinal medicines.

The change in enthalpy, or heat, of a chemical reaction is equal to the change in internal energy of the system plus the work done on the system.
The enthalpy of a system is the sum of its internal energy and the product of its pressure and volume.
In order to change a solid into a gas, the enthalpy of the system must increase by the amount of heat needed to break the intermolecular attractions between the particles of the solid.

The heat of vaporization of ammonia is 23.6 kJ/mol.

Answers

Sodium and potassium are in the same group because they're both transition metals. Transition metals have a number of properties that make them useful for certain situations. They're reactive, which means they can be easily manipulated. They tend to be abundant, which makes them useful for industrial purposes. And they can form different compounds with each other, which means that when you add them together, you get something new altogether.

This also means that sodium and potassium react with each other easily: in a reaction between the two of them, their electrons leave their outer shells and combine with an electron from another atom or molecule (in this case water). This leaves the atoms with unpaired electrons—which are highly reactive—and creates an energy-rich compound called an ionic bond.

When a tree is growing on a rock its weight can crush the rock, as a form of mechanical weathering is not a way trees are considered to affect weathering

Weathering is a process that breaks down or disintegrates the rocks which are present on the surface of our planet. Biological life can also affect weathering in many ways.

Tree roots can grow through rock cracks causing the cracks to expand. Sprouts can start to grow near cracks in rocks. The sprout when it grows would start to put pressure on the rocks by the roots that would penetrate them and also by the weight it exerts when it turns to a tree.

Tree’s roots (and other vegetation) can release acids that can cause weathering of rock. Plants are capable of producing acids to protect themselves against invaders like microbes and insects. When plants release acids, it would change the chemical composition of the rock that would eventually break the rock. This type of weathering is called chemical weathering

Trees (and other vegetation) when decomposing can cause chemical weathering. When trees decompose it could produce acids like carbonic acid that would help in disintegration of rocks.

When a tree is growing on a rock its weight would not directly crush the rock, as a form of mechanical weathering. Rocks with crack would be the main source of mechanical weathering by rocks.

So, the volume of the air tank will be:

[tex]\begin{gathered} V_2=\frac{4}{3}\pi\times(31.5cm)^3=13.1\times10^4cm^3 \\ V_2=13.1\times10^4cm^3\times\frac{1L}{1000cm^3}=131L \end{gathered}[/tex]

We clear P2 and replace the known data:

[tex]\begin{gathered} P_2=\frac{V_1P_1}{V_2} \\ P_2=\frac{5300L\times1atm}{131L}=40.5atm \end{gathered}[/tex]

The air must be compressed at 40.5atm

Answer: 40.5
