Chemistry
1 answer:
Vitek1552 [10]3 years ago
6 0

Answer:

The answer to your question is the first choice (H₂)

Explanation:

Process

Look for the electronegativity of the elements of this exercise

a) H₂ = 2.2 - 2.2 = 0

b) NaF = 3.98 - 0.93 = 3.05

c) HBr = 2.96 - 2.2 = 0.76

d) HS⁻ = 2.58 - 2.2 = 0.38

The molecule that has the smallest difference in electronegativity is H₂

A) ¿Cuáles son las partículas elementales que componen la materia, b) cuál es su ubicación, c) su carga eléctrica?
loris [4]

Las 3 partículas elementales son a) electrón, protón y neutrón. Se encuentran b) electrón en las órbitas electrónicas, el protón y el neutrón están en el núcleo. Sus cargas son c) electrón-negativo; protón-positivo; neutrón-sin carga. (Opción A).

Según el modelo atómico moderno, las partículas elementales que componen la materia son:

  • Electrón, se ubica en las órbitas electrónicas y tiene carga negativa.
  • Protón, se ubica en el núcleo y tiene carga positiva.
  • Neutrón, se ubica en el núcleo y no tiene carga

Las 3 partículas fundamentales son a) electrón, protón y neutrón. Se encuentran b) electrón en las órbitas electrónicas, el protón y el neutrón están en el núcleo. Sus cargas son c) electrón-negativo; protón-positivo; neutrón-sin carga. (Opción A).

Based on the number of valence electrons indicated by its location in the periodic table, which element's behavior would you pre
katrin [286]

Answer:

D

Explanation:

Elements in the same group (vertical columns) have the same number of valence electrons. These elements behave similarly because they will either give up or take the same number of electrons to fill their valence shell. Since potassium has 1 valence electron, it will most likely give up one electron. Out of all of the answer options, the only element that is in the same group as potassium is francium.

How is electromagnetic energy fromthe microwave transformed into heat energy
zysi [14]

Answer:


First, the microwaves transmit kinetic energy to the water molecules of the food, heating the water molecules. Only, those that are not very deep into the food.


Second, the hot water molecules transmit heat by conduction to the other parts of the food.


Explanation:


1) Microwaves are a form of electromagnetic radiation. The same as any wave, they carry energy.


2) The wave length of microwaves are in the range of 0.001 mm to 1 m (shorter than radio waves and longer than infrared)


3) The microwaves of an oven, used to heat food, have a wave length aroun 12 cm.


4) The microwaves transmit energy to the water molecules in the food, by increasing the kinetic energy of water molecules. As result, the water molecules get hotter. Microwaves only penetrate about 1 cm inside the food (a potato for example) and from that the heat is transferred by conduction to the inner parts of the food.
