The melting point of ice is 0°C: thus is a fact based on repetitive experiments


Repeated observations have consistently

shown that oppositely charged objects

attract each other: this is law


When the elements carbon and nitrogen

are mixed at 1500°C, they will react

with each other.

this is a hypothesis

Atoms are made of protons, neutrons,

and electrons. Although we can’t directly

see these particles, this structure

explains many experimental observations

escribe los valores de los cuatro numeros cuanticos para los electrones de los elementos:berilio y nitrogeno ayuda pls
valkas [14]
<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>

Would it be C..? <br> More NO2 and SO2 would form..help..please and thank you
Scorpion4ik [409]

Answer:

C. More NO2 and SO2 will form

Explanation:

Le Chatelier's Principle : It  predicts the behavior of equilibrium due to change in pressure , temperature , volume , concentration etc

It states that When external changes are introduced in the equilibrium then it will shift the equilibrium in a direction to reduce the change.

In given Reaction SO3 is introduced(increased) .

So equilibrium will shift in the direction where SO3 should be consumed(decreased)

Hence the equilibrium will go in backward direction , i.e

NO + SO_{3} \rightarrow NO_{2} + SO_{2}

So more and more Of NO2 and SO2 will form

What is the average atomic mass of the element?
morpeh [17]

The average atomic mass of element X is 14.007 u.

The average atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).

Thus,  

0.996 36 × 14.003 u =13.952 03 u

0.003 64 × 15.000 u = <u>0.054 60 u</u>

__________TOTAL = 14.007     u
