How many grams of boric acid (to two decimal places) are required to make 850 ml of the the stock solution?

Answers

Answer 1

To prepare 1 M, 850 ml boric acid solution, 52.7 gm solute is reported.

What is stock solution?

Simply said, a stock solution is a concentrated form of the "working solution" you used to conduct your experiment. This is typically done if the more diluted working solution degrades or decomposes quickly over time.

Stock solutions are used to speed up the preparation process, save time and resources, free up space in storage, and increase the precision with which working lower concentration solutions are made. The main benefits of adopting stock solutions are that they are easier to measure and save time when manufacturing solutions.

We know that,

Molarity (M) = Moles of solute ÷ liters of solution

Let's assume to prepare 1M, 850 ml (= 0.85 liter) boric acid solution, X mole solute is required.

So,  1 = X ÷ 0.85

Or,.  X = 0.85

Molecule weight of boric acid  62 gm.

So,

    1 mole boric acid = 62 gm boric acid

   0.85 mole boric acid = 62×0.85 gm. Boric acid

                                     = 52.7 gm.

To prepare 1 M, 850 ml boric acid solution, 52.7 gm solute is reported.

Quantization means that only specific values are allowed

what are quantized and continuous theories?

If the energy levels are continuous then a particle (or system) can have any energy in that interval. If they are quantized  say E1,E2..., then a particle (or system) can have only one of those energies, and not anything in between them.Quantization of energy is not a consequence of Schrödinger equation, instead it is a consequence of confinement. Energy levels in quantum systems are not always quantized. On the other hand,  classical systems also exhibits quantization of the energy levels. For example, consider the allowed frequencies of a string with fixed length (confinement) like in a guitar or violin. In such string, the allowed "energy states" corresponds to frequencies (harmonics) which are multiples of a fundamental frequency (first harmonic). Energy level are quantized if wavefunction is confined in finite space. eg; atomic orbital or quantum well. Energy level in solids are continuous while in gases they are quantized.In a solid energy levels are also quantized but the difference between levels decreases as the system size increases. Thus in the thermodynamical limit (large system sizes), these quantized energy levels become a continuum of states.

Thus we can conclude that quantization of energy levels appears both in quantum and classical mechanics

What product should be obtained if benzyne is generated in the presence of 1,3-butadiene?

Answers

3-bromo-1-butene is the end product of adding 1 equivalent of HBr to 1,3-butadiene.

What is butene ?

The alkene butene, often known as butylene, has the chemical formula C4H8. Any of the several chemicals may be referred to by the word "butene." They are odorless gases that are found in crude oil in trace amounts that are insufficient for practical extraction.

In the manufacturing of rubber and gasoline, 1-butene is used to create a wide range of compounds. Alkylate and polymer gasoline are used to make more than half of the butene produced worldwide. A third is utilized directly as fuel, primarily as fuel gas or blendstock for gasoline, without any conversion.
