The gas in a 225. 0 ml piston experiences a change in pressure from 1. 35 atm to 2. 60 atm. What is the new volume (in ml) assuming the moles of gas and temperature are held constant?.

Answers

Answer 1

1 atm (275 mL) equals 3.10 atm V2, where V2 is equal to 275 mL divided by 3.10, and P1V1 equals P2V2. The calculation is 1(275) = 3.1 (88.71) = 275.

How does chemistry deal with pressure?

The ideal gas equation can be changed to demonstrate that the pressure of a sample of gas is directly proportional to the amount of gas present, volume, and temperature is held constant: P=n(RTV)=n×const

V1 T1 V2 T2 is what formula?

Volume and temperature are related as follows: V1 / T1 = V2 / T2, where V1 and T1 represent the beginning volume and absolute temperature, and V2 and T2 represent the final volume and absolute temperature (the Kelvin temperature, not the Celsius temperature).

Vinegar has a concentration of 0.87mol/L acetic acid to make a 100ml solution it is diluted by a factor of 10 how do u find the original volume of vinegar and the concentration of acetic acid in the diluted solution

Answers

To find the original volume of vinegar, we can use the following formula:

Original volume of vinegar = Diluted volume * Dilution factor

In this case, the diluted volume is 100 ml and the dilution factor is 10, so the original volume of vinegar is:

Original volume of vinegar = 100 ml * 10 = 1000 ml

To find the concentration of acetic acid in the diluted solution, we can use the following formula:

Diluted concentration of acetic acid = Original concentration of acetic acid / Dilution factor

In this case, the original concentration of acetic acid is 0.87 mol/L and the dilution factor is 10, so the diluted concentration of acetic acid is:

Diluted concentration of acetic acid = 0.87 mol/L / 10 = 0.087 mol/L

This means that the diluted solution has a concentration of 0.087 mol/L acetic acid.

One mole or 239.2 g of PbO₂ or 239.2 g gives two moles or 606.5  of lead sulphate. Thus, 23.6 g of lead oxide will give 59.84 g of lead sulphate.

What is lead oxide?

Lead oxide is an ionic compound formed by the ionic bonding between the transition metal lead and oxygen by losing two electrons from lead to oxygen. It reacts with sulphuric acid giving lead sulphate PbSO₄.

As per the given balanced reaction, one mole of lead oxide gives two moles of lead sulphate.

Molar mass of PbO₂ = 239.2 g/mol

Molar mass of  PbSO₄ = 303.27 g/mol

2 moles of  PbSO₄ = 2 × 303.27  = 606.54 g.

Thus, 239.2 g of lead oxide gives 606.54 g of PbSO₄. The mass of PbSO₄ produced from 23.6 g of lead oxide is:

How has the discovery of DNA affected the classification of protists?

Answers

The discovery of DNA has had a significant impact on the classification of protists, which are a diverse group of eukaryotic organisms that include algae, protozoa, and slime molds. Before the discovery of DNA, protists were classified primarily based on their physical characteristics, such as their size, shape, and mode of locomotion. However, this approach to classification was limited because it did not take into account the evolutionary relationships between different protist groups.

With the discovery of DNA and the development of molecular techniques for analyzing genetic material, scientists were able to analyze the genetic makeup of different protist species and use this information to classify them in a more accurate and meaningful way. By comparing the DNA sequences of different protist species, scientists were able to determine which species were closely related and which were more distantly related. This led to the development of new classification systems that were based on evolutionary relationships rather than just physical characteristics.

Overall, the discovery of DNA has greatly enhanced our understanding of protist evolution and has allowed for more accurate and meaningful classification of these organisms. It has also led to the discovery of many new protist species and the reclassification of previously known species into new taxonomic groups.

calculate the phph of a solution in which one normal adult dose of aspirin (640 mgmg ) is dissolved in 6.0 ounces of water.

Answers

The pH of the solution in which one normal adult dose aspirin is dissolved is 2.6 .

Given,

mass of aspirin = 640 mg = 0.640 g

volume of water = 6 ounces = 6 × 0.0295735 L = 0.177441 L

molar mass of aspirin = 180.16 g/mol

moles of aspirin = mass / molar mass = 0.00355 mol

The pH of the solution is as follows,

concentration of aspirin = moles of Aspirin / volume of water

= 0.00355 / 0.177441

= 0.021 M

Given that pKa of Aspirin = 3.5

pKa = -logKa

Therefore, Ka = 3.162 × 10⁻⁴

From the Ice table

3.162 × 10⁻⁴ = [x + H⁺]/[aspirin] = [x²]/[0.021 - x]

Given that the value of Ka is small so we will ignore -x

x² = 3.162 × 10⁻⁴ × 0.021

x = 2.576 × 10⁻³

Therefore,

[ H⁺ ] = 2.576 × 10⁻³

given that

pH = - Log [ H⁺ ]

     = - ( -3 + log 2.576 )

     = 2.58 ≈ 2.6

Answers

1.56% would be the percentage of the original sample would be left after 108 days.

What is  a radioactive element?

Radioactive elements are composed of atoms with unstable nuclei and emit atomic radiation as part of the stabilization process. Emission of radiation transforms radioactive atoms into different chemical elements. This chemical element is either stable or highly radioactive, so it decays further. Since some elements in nuclei are unstable due to the presence of excess nuclear charge, these nuclei undergo radioactive decay to form stable nuclei. These elements are called radioactive elements.

The nuclear stability of the elements can be calculated from the n/p (neutron-proton ratio). Elements with atomic numbers up to Z=20 are stable and contain the same number of protons and neutrons. As the atomic number increases, the repulsion between protons increases, requiring more protons and neutrons. Therefore, the neutron-to-proton ratio of stable nuclei increases with increasing atomic number.

Therefore, 1.56% would be the percentage of the original sample would be left after 108 days.

if your isolated product has succinimide present, what key feature should be present in the ir spectrum of your product?

Answers

If our product includes succinimide, the IR spectra should show a prominent peak at around 1700 cm-1, suggesting an incomplete reaction.

What function does succinimide serve?

There are several applications for these chemicals. The succinimides ethosuximide, phensuximide, and methsuximide are among the medications used as anticonvulsants. Succinimides are also utilized in a number of test procedures to create covalent connections between peptides or protein chains and polymers.

What is the Succinimides' mode of action?

Succinimides inhibit voltage-dependent calcium leakage in thalamic neurons via acting on calcium T channels. Either the gastrointestinal system (vomiting, nausea, and abdominal discomfort) or the central nervous system are ethosuximide's side effects (lethargy, dizziness, and ataxia).
