Select all of the following statements that are basic assumptions of the Bohr model of the atom. Atoms have a central nucleus wi
Alekssandra [29.7K]

Answer:

The assumptions of the Bohr model of the atom are:

- Atoms have a central nucleus with electrons in orbit about this nucleus.

- They must gain energy to jump to a higher level, and they release energy when jumping to a lower level.

- Electrons orbit the nucleus, but the orbits can have only certain sizes and energy values.

Explanation:

The Bohr model of the atom establishes that atoms have a central nucleus with positive charge and electrons (with a negative charge) in orbit about this nucleus. In the Bohr model, electrons move in specific orbits with a certain amount of energy and can't jump from one orbit to another around the nucleus. To jump to a higher level, they must gain energy or release energy when jumping to a lower level.

The Thomson model of the atom postulated that <em>atoms are solid spheres of matter</em> and <em>are made of positive material with electrons fixed in place in this positive material</em>.

How many grams of hydrogen gas will form in this equation?
FrozenT [24]
The Law of Conservation of Mass states that matter cannot be created nor destroyed. The first two reactants have a total of 23 grams so therefore the product must have 23 grams as well.
23 - 16 = 7
There would be 7 grams of hydrogen gas.

Andre45 [30]

Answer:

d) Combustión.

Explanation:

¡Hola!

En este caso, dado que estamos enfocados en el concepto de cambio químico, el cual se caracteriza por exhibir un cambio en la composición e identidad de las sustancias iniciales (reactivos) a otras finales (productos).

Ahora bien, como se nos dice que los productos de este cambio químico son energía, agua y dióxido de carbono, inferimos que el nombre de este proceso es d) Combustión, por ejemplo la combustion del gas natural para calentar nuestras comidas en la cocina.

¡Saludos!
