What is the concentration ofthe bromide ion if25.0 ml of a 0.50 m aibr3 solution combines with 40.0 ml of a 0.35 m nabr solution? assume volumes are additive.

Answers

Answer 1

The concentration of the bromide ion if the given solutions are combined would be 0.79 M.

Since the volumes are additive

Total final volume = 25 ml + 40 ml = 65 ml

Final concentration of AlBr3 in Solution : 25 ml X 0.5 M = 65 ml X x M

                                                                   : x = 0.192 M

Final concentration of NaBr in Solution : 40 ml X 0.35 m = 65 ml X x M

                                                                 : x = 0.215 M

Br- from AlBr3 : 0.192 * 3 = 0.576 M Br-

Br- from NaBr : 0.215 * 1 = 0.215 M Br-

Total Br- from the solution made would be : 0.576 + 0.215 ≈ 0.79 M

Orange light has a frequency of 4.8×1014 s−1. What is the energy of one quantum of orange light?

Answers

The energy of one quantum of orange light, given that it has a frequency of 4.8×10¹⁴ s⁻¹ is 3.18×10⁻¹⁹ J

How do I determine the energy?

We know that energy and frequency are related according to the following equation:

Energy (E) = Planck's constant (h) × frequency (f)

E = hf

Using the above formula, we can obtain the energy of one quantum of the orange light. Details below:

Frequency (f) = 4.8×10¹⁴ s⁻¹Planck's constant (h) = 6.626×10⁻³⁴ JsEnergy (E) = 6.23×10⁻¹⁹ J

Energy (E) = Planck's constant (h) × frequency (f)

E = hf

E = 6.626×10⁻³⁴ × 4.8×10¹⁴

The number of bonds each atom makes to surrounding atoms
The number of neutrons in the nucleus
High levels of chaotic atomic geomtetry
The structures' atomic symmetry and geometry - crystal structure

Answers

The correction options are;

The number of bonds each atom makes to surrounding atomsThe structures' atomic symmetry and geometry - crystal structure

Further Explanation

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. The close-packed and more complex structures are inherently harder, and may be expected, therefore, to be better base materials for high strength alloys.

Answers

The rate of forward and reverse reaction.

Equilibrium occurs when the rates of the forward and reverse reactions are equal.

At equilibrium, the concentrations of each reactant and product are both constant. The ratio of the reactant and product concentrations does not vary at the equilibrium temperature when a reaction is at an equilibrium state. This indicates that the concentrations of the reactants and products remain unchanged at equilibrium.

It may also refer to an object's resistance to a change in velocity.An object is said to have inertia if no external force forces it to change its speed or direction from its current state. Newton's first law of motion included a description of the concept of inertia. It is a propensity to do nothing or to do nothing different.Unless acted upon by an unbalanced force, an object remains at rest and an object in motion will remain to move at a constant speed and in a straight line.

461 j of energy is transferred to a system consisting of 2.0 moles of an ideal gas. if the volume of this gas stays at a constant 3.4 l, calculate the change in internal energy of the gas.

Answers

The gas's internal energy has increased by 461 J.

Thermodynamics' first law states:

ΔE= q+ w

ΔE= Change in internal energy

q= heat released or absorbed

w=work done or by the system

w= work done on the system= -PΔV

Volume is constant

So, ΔV = 0 and w=0

So q=+461 J {Heat absorbed by the system is positive}

ΔE= +461+0= +461 J

Consequently, the gas's internal energy has increased by 461 J.

A thermodynamic system's internal energy is the total amount of energy it contains. The energy required to create or prepare the system in its current internal condition comprises both internal kinetic energy and potential energy contributions. It keeps track of the system's energy gains and losses brought on by adjustments to its internal state. It excludes all external energies from surrounding force fields as well as the kinetic energy of motion of the entire system. The first law of thermodynamics, which is based on the idea that an isolated system has constant internal energy, is known as the law of conservation of energy.

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.

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

The electronegativity is n < p < ge < ga.

What is electronegativity?

Electronegativity is a measure of an atom's ability to attract electrons when it forms a chemical bond with another atom. It is based on the Pauling Scale, which assigns values to elements based on their tendency to attract electrons when they form bonds. Electronegativity increases from left to right across the periodic table, and increases from the bottom to the top of the periodic table.

The correct answer is n < p < ge < ga. This is because electronegativity increases as we move down a group in the periodic table and from left to right across a period.

Answers

The number of bohr magnetons per atom for this material is 1.14 when some hypothetical metal that exhibits ferromagnetic behavior and that has 1 simple cubic crystal structure.

Given atomic radius of crystal structure (r) = 0.130nm

saturation flux density of crystal structure = 0.75tesla

We know that n = M/µN = B/µ0µN

n = BVc/µ0µN where Vc is the volume of crystal and B is bohr magneton

n = B(2r)^3/µ0µN = 0.75x(2x0.130x10-9)^3)/(1.25x10-26x9.27x10-24)

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

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.
