Answer:

1) Electron

Explanation:

It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

What atomic or hybrid orbital on the central br atom makes up the sigma bond between this br and an outer f atom in bromine trif
Nataly_w [17]

Atomic or hybrid orbital on the central br atom makes up the sigma bond between this br and an outer f atom in bromine trifluoride, brf3 is sp2 hybridization

Trigonal hybridization is another name for sp2 hybridization. It entails combining one's' orbital with two 'p' orbitals of equal energy to create a new hybrid orbital known as sp2. A trigonal symmetry combination of s and p orbitals that is kept at 120

One of the hybrid orbitals formed when one s orbital and two p orbitals are mathematically merged to form three new equivalent orbitals orientated toward the corners of a triangle is sp2 hybridization.

The only feasible molecule geometry for sp2 hybridized center atoms is trigonal planar. When all of the bonds are in place, the shape is trigonal planar as well.

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>

If you were to react 4.3 miles of magnesium phosphide how many moles of potassium would you need?
bixtya [17]

Answer:

25.8

Explanation:

Let's write the reaction between magnesium-phosphide and potassium:

Mg3P2 + K = Mg + K3P

And now let's balance this equation:

Mg3P2+6K=3Mg+2K3P

We see that the ratio of magnesium-phosphide and potassium is 1:6, which means that for every mole of magnesium-phosphide there need to be 6 moles of potassium.

Since we have 4.3 moles of Mg3P2, there need to be 6 • 4.3 = 25.8 moles of potassium.
