<span>Hay cuatro números cuánticos: n, ℓ, m, y s. Cada uno es un factor particular en una ecuación que describe una propiedad del electrón. En este nivel introductorio, las ecuaciones no son necesarias. El valor de cada número cuántico se asigna a cada electrón en un átomo mediante un proceso de "construcción". Niels Bohr llamó a este proceso el principio de "Aufbau": aufbau significa "construir". N es SIEMPRE el punto de partida para construir una serie de números cuánticos. Cada número cuántico se asigna entonces de acuerdo a un conjunto de reglas, cada una de las cuales tomó años de estudio para finalmente determinar. Las reglas NO son sólo las viejas arbitrarias; Se han determinado a partir de un estudio de la naturaleza. Recuerde las reglas: (1) n = 1, 2, 3, y así sucesivamente. (2) ℓ = 0, 1, 2,. . . , N - 1 (3) m empieza en negativo ℓ, pasa por números enteros a cero y luego pasa a ℓ positivo. (4) después de haber determinado los n, ℓ y m, asignar el valor +1/2 a un electrón, luego asignar -1/2 al siguiente electrón, utilizando los mismos valores n, ℓ ym. Además, tenga en cuenta que usamos sólo un valor n, ℓ, m, y s para hacer un conjunto de cuatro números cuánticos para cada electrón. Es el conjunto que identifica de forma única cada electrón. Último punto: la última columna de cada tabla se denomina "Nombre Orbital". Al leer este tutorial, es posible que aún no sepa lo que es un orbital. Eso está bien, pero por favor entienda el concepto llamado "orbital" es importante. Aquí está una descripción simple real que ignora muchos detalles: cada orbital es una región del espacio alrededor del núcleo que contiene un MÁXIMO de dos electrones. Darse cuenta de que es más complejo que eso, pero la descripción anterior es lo suficientemente bueno por ahora. </span>

Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing the composition of the subject. Descriptive words that would help to identify a substance’s physical property include hard, soft, brittle, flexible, heavy, and light just to name a few. Let’s say you’re eating, throughout the day your stomach starts to growl that is what happens when your stomach is digesting your food. Digestion is an example of chemical change. Chemical change happens every day and more than half the time we don’t realize it whether it’s metal starting to rust, or our food starting to rot. Physical change can happen when your popsicle starts to melt, or your water starting starting to boil. These are examples of physical change.

A student dissolves 3.9g of aniline (C6H5NH2) in 200.mL of a solvent with a density of 1.05 g/mL . The student notices that the
tino4ka555 [31]

Answer:

2.1 × 10⁻¹ M

2.0 × 10⁻¹ m

Explanation:

Molarity

The molar mass of aniline (solute) is 93.13 g/mol. The moles corresponding to 3.9 g are:

3.9 g × (1 mol/93.13 g) = 0.042 mol

The volume of the solution is 200 mL (0.200 L). The molarity of aniline is:

M = 0.042 mol/0.200 L = 0.21 M = 2.1 × 10⁻¹ M

Molality

The moles of solute are 0.042 mol.

The density of the solvent is 1.05 g/mL. The mass corresponding to 200 mL is:

200 mL × 1.05 g/mL = 210 g = 0.210 kg

The molality of aniline is:

m = 0.042 mol/0.210 kg = 0.20 m = 2.0 × 10⁻¹ m

In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions
padilas [110]

Answer:

\triangle G= -6.7 KJ/mol

Explanation:

From the question we are told that:

Chemical Reactions:

X=A⇌B,ΔG= 14.8 kJ/mol

Y=B⇌C,ΔG= -29.7 kJ/mol

Z=C⇌D,ΔG= 8.10 kJ/mol

Since

Hess Law

The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the number of steps taken.

Therefore

Generally the equation for the Reaction is mathematically given by

T = +1 * X +1 * Y +1 *Z

Therefore the free energy, ΔG is

\triangle G=1 * \triangle G*X +1 * \triangle G*Y +1 * \triangle G *Z

\triangle G= +1 * (14.9) +1 * (-29.7) +1 * (8.10)

\triangle G= -6.7 KJ/mol

A mixture of 454 kg of applesauce at 10 degrees Celsius is heated in a heat exchanger by adding 121300 kJ. Calculate the outlet
stira [4]

Explanation:

The given data is as follows.

           Mass of apple sauce mixture = 454 kg

           Heat added (Q) = 121300 kJ

 Heat capacity (C_{p}) of apple sauce at 32.8^{o}C = 4.0177 kJ/kg^{o}C

So, Heat given by heat exchanger = heat taken by apple sauce

                            Q = mC_{p} \Delta T

or,                    Q = mC_{p} (T_{f} - T_{i})  

Putting the given values into the above formula as follows.

                     Q = mC_{p} (T_{f} - T_{i})  

              121300 kJ = 454 kg \times 4.0177 kJ/kg^{o}C \times (T_{f} - 10)

                      T_{f} = 76.5^{o}C

Thus, we can conclude that outlet temperature of the apple sauce is 76.5^{o}C.
