Which solution of salt nacl or CaCl2 is better to salt the roads?

Answers

Calcium chloride is a better solution of salt to salt the roads.

In the countries where the climate is very cold, the solution of calcium chloride and water is mixed and used for clearing the ice on the road.

The mixture of calcium chloride CaCl₂ and water is called eutectic mixture.

This mixture has a very low freezing point in comparison to sodium chloride.

Sodium chloride NaCl, is also a good substitute for clearing ice but it has a much higher freezing point in comparison to calcium chloride.

This is why calcium chloride is always preferred over sodium chloride because it becomes easier for us to clean the roads.

Three students are asked to discuss the sources of error that might have affected the outcome of the lab. Select the student that employs correct scientific reasoning.
Student 1: If the spot was placed below the solvent level, this would cause the sample to be dissolved into the solvent pool before traveling up the plate.
Student 2: If the solvent used has the opposite polarity of the stationary phase this will cause unequal movement of the sample.
Student 3: If the developing chamber was closed too quickly than the sample wouldn't be able to travel on the TLC plate.

Answers

Student 1 is correct. He discovered the mistake as;

If the spot was placed below the solvent level, this would cause the sample to be dissolved into the solvent pool before traveling up the plate.

TLC should be positioned so that just the lowest edge of the plate touches the solvent.

Differential affinities (strength of adhesion) of the analyte components towards the stationary and mobile phases result in differential separation of the components. Affinity, in turn, is determined by two molecular properties: adsorption and solubility.

Adsorption is the property of how well a component of a mixture clings to the stationary phase, whereas solubility is the quality of how well a component of a mixture dissolves in the mobile phase.

The greater the adsorption to the stationary phase, the slower the molecule will move across the column.

The more the molecule adsorbs to the stationary phase, the slower it moves across the column.

The greater the molecule's solubility in the mobile phase, the faster it will travel across the column.

Thus, Student 1 is correct. He detected the error by placing the area below the solvent level, which caused the sample to disintegrate into the solvent pool before migrating up the plate.

How do you calculate the half-life of an isotope?

Answers

The half-life of an isotope t1/2 = 0.693 × No of atoms/no of decays

A quantity (of substance half-life )'s (symbol t12) is the amount of time needed for it to decrease to half of its original value. The phrase is frequently used in nuclear physics to refer to how long stable atoms last or how quickly unstable atoms decay radioactively. In a broader sense, the phrase is used to describe any exponential decay (or, very rarely, a non-exponential decay). For instance, the biological half-life of medications and other substances in the human body is discussed in the medical sciences. In exponential growth, doubling time is the opposite of half-life. A characteristic unit for the exponential decay equation, half-life is constant during the course of an exponentially decaying quantity's lifetime.

Answers

15.63 moles of HgO are needed to produce 250.0 grams of oxygen.

From the decomposition of HgO, we get mercury and oxygen:

            HgO  → 2Hg + O₂ ---- It is a decomposition reaction.

Now, we need to find moles of HgO needed to produce 250.0 grams of oxygen.

So, the Mass of O₂ = 250.0 grams

Number of moles of the oxygen = Mass of Oxygen/Molar mass

= n(O₂) = m/M

= 250/32

= 7.81 moles

moles of HgO = 2 times of moles of Oxygen

n(HgO) = 2 × n(O₂)

what is the volume (in liters) of this air sample if the pressure is changed to 0.960 atm at a constant temperature? do not include the unit of measure in your answer.

Answers

According to Boyle's law, in any ideal gas, the pressure exerted by the gas and its volume is inversely proportional to one another, considering it to be at a constant temperature.

This law is applicable in case of respiration also. When the air is inhaled, the diaphragm is raised, as a result of which the pressure exerted on the lungs increases and eventually allows the air to flow into the lungs.

We use Boyle Mariotte's formula: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally.

We convert the unit volume in ml into

L: 200 / 1000 = 0.2  and 50 / 1000=0.05

P₁xV₁=P₂xV₂

V₂= (P₁xV₁)/P₂

= (0.96 atm x 0.2L) / 0.05

= 3.84 L

Therefore, using Boyle's law, we got the volume changed will be 3.84 L.

7,493.1 g of methanol must be dissolved in 313.0 mL of ethanol to prepare a 0.750 M solution.

What is dissolved?

Dissolved is a term used to describe when a solid material has been completely broken down into particles small enough to be suspended in a liquid. This process is known as dissolution, and can be achieved through a variety of different methods. One of the most commonly used methods is mechanical agitation, which involves using mechanical force such as stirring or shaking to cause the solid particles to break down and become suspended in the liquid. This process can be used to dissolve a wide range of different compounds such as salts, sugars, and acids. Other methods of dissolution include chemical reactions, heating, and the use of solvents. Dissolution is a key part of many chemical processes, and its importance in chemistry cannot be overstated.

Molar mass of methanol (CH3OH): 32.04 g/mol
Molarity of solution: 0.750 mol/L
Volume of solution: 313.0 mL
Therefore, the number of moles of methanol required in solution = 0.750 mol/L × 313.0 mL = 234.75 moles
Mass of methanol required = 234.75 moles × 32.04 g/mol = 7,493.1 g
