Answers

If  the vapor pressure of pure methanol at 50 °c is 400 torr. The change in vapor pressure of a solution made from 23.5 g of glycerin in 130 g of methanol at 50 °C  is 24 torr.

The vapor pressure is given as :

p = x1 p°1

The lowering in vapor pressure :

Δp = p°1 - p1

     = p°1 - x1p°1

    = p°1 ( 1 - x1)

Δp = x2 p°1

Moles of glycerin = 23.5 / 92

                              = 0.255 mol

Moles of methanol = 130 / 32

                                = 4 mol

Total moles = 0.25 + 4

What imilaritie and difference can you identify between neon ign and firework? What might be happening at the atomic level ti explain thee difference?

Answers

Neon lights and fireworks are both types of light sources that produce bright and colorful displays. However, the main difference between them is that neon lights are a continuous source of light, whereas fireworks are a transient source of light.

Neon lights produce light through the process of gas discharge, where an electric current is passed through a gas-filled tube, causing the gas to emit light. The light is produced by the excitation of atoms within the gas, which then release photons as they return to their ground state.

Fireworks, on the other hand, produce light through a chemical reaction, where a mixture of chemicals is ignited, producing a burst of light and color.

The light is produced by the energy released during the chemical reactions, which excites the atoms and molecules within the fireworks, causing them to emit light. The main difference is that neon lights rely on a continuous energy source while fireworks rely on a chemical reaction.

When does the Lake-Effect Snow STOPs?

Answers

The timing of when lake-effect snow stops depends on several factors, including the temperature and wind patterns. Typically, lake-effect snow will stop when the temperature warms up, or when the wind direction changes so that it is no longer blowing over the lake.

What is Lake-effect snow?

Lake-effect snow is a type of precipitation that occurs when cold air moves over a large body of relatively warm water, such as a lake. The air picks up moisture from the lake and as it rises, it cools and the moisture condenses into snow.

The snowfall can be intense and localized, and it typically stops when the temperature inversion breaks down, or when the wind direction changes so that it is no longer blowing over the lake.

How many molecules are there in 2. 0 moles of H2O?.

Answers

2.0 moles of H2O contain 2.0 x Avogadro's number of molecules, which is 6.022 x 10^23 molecules.

This is because represents the number of atoms or molecules in one mole of a substance. In one mole of any substance 6.022 × 10²³ particles of that substances are present, which is also known as Avogadro's number. So, in 2 moles of H₂O = 2(6.022 × 10²³) = 12.044 × 10²³ molecules will present. Therefore, multiplying Avogadro's number by the number of moles of a substance gives the number of atoms or molecules present in that substance.

Is HF a nonpolar covalent bond?.

Answers

HF is a polar covalent bond. The difference in electronegativity between hydrogen and fluorine causes the electrons in the bond to be unevenly distributed, resulting in a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine atom.

This creates a polar bond rather than a nonpolar covalent bond. In a nonpolar covalent bond, the electrons are shared equally between the two atoms, resulting in no net dipole (separation of charge).

However, in a polar covalent bond, the electrons are not shared equally, resulting in a net dipole. The difference in electronegativity between the atoms causes one atom to have a stronger attraction for the electrons than the other, resulting in a partial positive charge on one atom and a partial negative charge on the other.

In the case of the HF molecule, the fluorine atom has a much higher electronegativity than the hydrogen atom.

As a result, the electron cloud is pulled more towards the fluorine atom, leaving the hydrogen atom with a partial positive charge (+) and the fluorine atom with a partial negative charge (-). This creates a polar bond with a net dipole moment, meaning that the molecule has a positive and a negative pole.

It is also important to mention that the polar nature of a covalent bond can also be determined by the molecular geometry.

The bond dipole moment is determined by the vector difference of the charges and the distance between them, so the bond dipole moment is zero in a symmetrical molecule but not in an asymmetrical one.

in step 6 of the citric acid cycle when succinate is converted to fumarate, hydrogen atoms are transferred to fad. the ____________ is catalyzed by a dehydrogenase enzyme.

Answers

The cycle of citric acid Hydrogen atoms are transported to FAD during the conversion of succinate to fumarate. This process is catalyzed by a succinate dehydrogenase enzyme.

During the process of succinate dehydrogenation, succinate is oxidized to fumarate by losing electrons, which are transferred to FAD, reducing it to FADH2. This transfer of electrons from succinate to FAD is an oxidation-reduction reaction, also known as redox reaction. The energy released during this reaction is harnessed to generate ATP, which is an important energy currency for the cell. Succinate dehydrogenase is an enzyme complex that contains multiple subunits and cofactors, including flavin adenine dinucleotide (FAD) and iron-sulfur clusters. It is located in the inner mitochondrial membrane, which allows it to transfer electrons to the electron transport chain, leading to the production of ATP. It's important to note that the citric acid cycle is a crucial metabolic pathway that takes place in the mitochondria of eukaryotic cells, and it is also known as the TCA cycle or Krebs cycle.

Answers

If a beaker of tetrahydrofuran is put inside a sealed tank containing tetrahydrofuran gas at 63 degrees Celsius and 810 torr, after ten minutes, the liquid in the beaker will evaporate and the amount of liquid in the beaker will decrease.

This is due to the fact that at a higher temperature and pressure, the vapour pressure of the liquid tetrahydrofuran in the beaker will increase, which means that more molecules of tetrahydrofuran will escape from the liquid phase into the gas phase. This process is known as evaporation. As more molecules of tetrahydrofuran evaporate from the liquid in the beaker, the amount of liquid in the beaker will decrease.

The pressure inside the tank is 810 torr and this pressure is greater than the vapour pressure of tetrahydrofuran at 63 degrees C, meaning that the vapour pressure of the liquid tetrahydrofuran will be less than the pressure inside the tank, it will escape to the gas phase, therefore the amount of liquid in the beaker will decrease.

Answers

78.3 Torr would be the vapor pressure of a mixture of 80 g of ethanol and 97 g of methanol at 293 k

This question can be answered using Raoult's law and Dalton's law of partial pressure.

Raoult's law: Raoult postulated a mathematical relation between partial pressure and mole fraction. This connection is known as Raoult's Law, which asserts that the partial vapour pressure of each volatile component in a solution (obtained by dissolving a solute in a solvent) is directly proportionate to its mole fraction. The formula can be given by:

p₁= p₁⁰x₁        p₂=p₂⁰x₂

Here x denotes the mole fraction

p⁰ denotes the pressure in pure state.

Dalton's law: Dalton's law of partial pressure states that a gas mixture's total pressure is equal to the sum of its component gases' partial pressures. The pressure that each gas would produce if it filled the same volume of the mixture by itself at the same temperature is known as the partial pressure.

Mathematically,

p= p₁ + p₂

here p is the total pressure.

Now according to the given question

given mass of ethanol= 80 gm

moar mass of ethanol= 46 gm/mol

no. of moles= [tex]\frac{given mass}{molar mass} = \frac{80}{46} = 1.7 moles[/tex]

given mass of methanol= 97gm

molar mass of methanol= 32 gm/mol

no. of moles= [tex]\frac{given mass}{molar mass} = \frac{97}{32} = 3 moles[/tex] (approx.)

total number of moles= 1.7+3= 4.7 moles

mole fraction x for ethanol= [tex]\frac{1.7}{4.7} =0.36[/tex]

mole fraction of methanol= 1-0.36= 0.64

given pressure of ethanol in pure state= 97.7 Torr

given pressure of methanol in pure state= 44.6 Torr

Now from dalton's ;aw

total pressure is the sum of product of partial fraction and pressure in pure state for individual liquids.
