Match each section of the atomic structure

Chemistry
2 answers:
siniylev [52]3 years ago
6 0

Answer:

1e 2a 3d 4c 5d

Explanation:

1) Electrons

These particles spin around the nucleus of the atom, they are negatively charged. They have their orbits.

2) Protons

This another kind of subatomic particle, is located on the nucleus of the atom is positively  charged they constitute the atomic nuclei with the other main particle

3) Neutrons

They do not possess electric charge, all atoms but the Hydrogen have neutrons within. Neutrons and Protons form the Atomic Nuclei.

4) Electron Cloud

Even though, this illustration is transparent maybe a translucid one should be more appropriate. An Electron Cloud depicts an area and the electron is not depicted as a dot. So, again this is not the best picture of an Electron Cloud, the point is since we can't precisely say where the electron passes let's draw areas, instead of lines.

5) Nucleus

The mass of particles at the center whose constituent parts are mainly the protons and neutrons and other subatomic particles, not mentioned here as quarks, bosoms, etc.

<>"Atomic particles. Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus. The electron cloud has a radius 10,000 times greater than the nucleus."<>

Given the equation representing a system at equilibrium:
Yuliya22 [10]

Answer:

increasing the temperature

Explanation:

Now look carefully at the reaction equation, notice the inclusion on an energy term on the left hand side;

PCl5(g) + energy ⇌ PCl3(g) + Cl2(g)

The inclusion of an energy term means that the reaction is endothermic. Energy is absorbed as the reaction goes from left to right.

Since energy is absorbed, increasing the temperature (supplying energy in the form of heat) will favour the forward reaction over the reverse reaction in accordance with Le Chatelier's principle. Hence the answer.

Why might a scientist repeat an experiment if she did not make a mistake in the first one? A) Scientists who repeat experiments
9966 [12]

Answer:

The correct answer is B) it helps to ensure the result are consistent and repeatable.

Explanation:

Scientist generally repeat an experiment if he or she did not make a mistake in the first one to compare the results of two experiment, if there is no difference in the result or values obtainted from the observation of two experiment. he or she become sure that experiment was done in a right way because if there is some error made when experiment was carried out then the result of two same experiment would be different.

When the equation below is correctly balanced, the coefficient for CO2 is
vaieri [72.5K]

Answer:

The answer to your question is 4

Explanation:

Chemical reaction

                C₂H₆  +  O₂  ⇒  CO₂  +  H₂O

           Reactants    Elements    Products

                  2            Carbon              1

                  6            Hydrogen         2

                  2            Oxygen             3

Balanced chemical reaction

                2C₂H₆  +  7O₂  ⇒  4CO₂  +  6H₂O

           Reactants    Elements    Products

                  4            Carbon             4

                 12            Hydrogen       12

                 14            Oxygen           14

When the reaction is balanced the coefficient for CO₂ is 4.
