is active transport required to move molecules from high to low concentration or low to high concentration? why?

Answers

Answer 1

Moving chemicals from a low-concentration area to a high-concentration area is known as active transport. This process is "active," which implies it consumes energy (usually in the form of ATP).

What does high concentration mean in chemistry?

Chemical solutions that contain a significant quantity of solute at high concentrations are referred to as concentrated. A solution is considered to be saturated if it has been concentrated towards the point that no more solute can dissolve in the solvent.

Greater concentration equates to more particles, right?

Concentration: As the concentration rises, more particles will be present in a given volume. The likelihood of successful collisions increases as the number of particles increases. Greater response speeds imply increased collisional success.

assume there exists some hypothetical methat that exbihits ferromagnetic behavior and that has 1 simple cubic crystal strecutre, and atomic radius of 0.130 nm and a saturation flux density of 0.75 tesla. determine the number of bohr magnetons per atom for this material

Answers

When compared to a hypothetical ferromagnetic metal with a single simple cubic crystal structure, this substance possesses 1.14 bohr magnetons per atom.

Given that the cubic crystal  atomic radius (r) is 0.130 nm

crystal structure's saturation flux density is equal to 0.75 tesla.

We are aware that n = M/N = B/0N.

n = BVc/0N, where BVc is the bohr magneton and Vc is the volume of the crystal.

N = 0.75x(2x0.130x10-9)3)/n = B(2r)3/0 (1.25x10-26x9.27x10-24)

n = 13.18x10-30/11.5x10-50 = 1.14x10^20

Therefore, this cubic crystal substance has 1.14 bohr magnetons per atom.

for water to change into the gas phase, energy is required to break hydrogen bonds between h2o molecules. this energy is referred to as: a. latent heat b. specific heat capacity c. sensible heat d. kinetic energy

Answers

For water to change into the gas phase, energy is required to break hydrogen bonds between H₂O molecules. This energy is referred to as Latent heat. So, the right option is A.

Energy is needed for the conversion of a solid into a liquid, a liquid into a gas, or a solid into a gas. Energy will be released during fusion, condensation, or the transformation of gas into solid or liquid.

Latent heat of evaporation is the term used to describe the energy needed to change a liquid into a gas.

The molecules of water in a liquid are held together by hydrogen bonds. A single molecule must therefore have enough energy to break all of its hydrogen bonds with neighboring molecules before dissolving in order for it to evaporate. Since this molecule must have obtained its internal energy from the remaining liquid, every vaporizing molecule absorbs the same quantity from it. For this energy loss, the phrase "latent heat of vaporization" is used.

So, the correct option is C. Latent heat.

describe the differences between electron transfers involving organic molecules that act as electron carriers (nad /nadh, fad/fadh2, q/qh2) and transfers involving the metals that act as electron carriers (fe2 /fe3 , cu /cu 2) in electron transport

Answers

The basic difference between NADH and FADH₂ is their tendency to donate electrons. NADH is a good donor of electrons in a redox reaction whereas FADH₂ is not that much good.

The electron transport chain is a collection of membrane-embedded proteins that are organised in four large complexes labelled from I to IV. In NADH electrons are in very high energy level as compared to FADH₂ ,  so they can be easily transferred to complexes through the four phases in a redox reaction but in FADH₂, the electrons are in a bit low energy level, so they are not transferred in a redox reaction through the membrane. The transfers involving the metals such as Fe₂ or Cu₂ that act as electron carriers in electron transport is formerly based on their valencey in the redox reactions. Hence, it's clear that the valency of metals plays a major role here and in organic molecules, tendency to  transfer electrons is significant.

if the mass ratio of k to f in a compound is 2.06, how many grams of f are needed to react with 2.30 of k?

Answers

To determine the number of grams of element "f" needed to react with 2.30 grams of element "k", you can use the mass ratio provided in the problem. First, let's call the mass of "f" that is needed x. The mass ratio tells us that the mass of "f" is 2.06 times the mass of "k", so we can set up the following equation:

2.06 * x = 2.30

To solve for x, we can divide both sides of the equation by 2.06:

x = 2.30 / 2.06

This simplifies to:

x = 1.12 grams

The number of bonds each atom makes to surrounding atoms contributes to the substance strength, the strength of a bond between two atoms increases as the number of electron pairs in the bond increases. Thus, we find that triple bonds are stronger and shorter than double bonds between the same two atoms; likewise, double bonds are stronger and shorter than single bonds between the same two atoms.

The crystal structure of a substance can contribute to its strength as it was found that the body-centered-cubic crystal structure is always the softer structure when it is involved in an allotropic transformation.
