Keith_Richards [23]

Answer:

Dipole-dipole forces

Explanation:

A polar compound is that compound which contains atoms that have a difference in charges i.e electrostatic attraction occurs between its constituent atoms. Polar molecules are attracted to other polar molecules with opposite charges and her held together with the aid of certain forces

The attractive force between the negative part of a polar molecule (-) and the positive part of another polar molecule (+) is called DIPOLE-DIPOLE FORCES. This dipole-dipole force gets stronger with an increasing polarity of the molecules involved.

Answer:

Electrones de valencia.

Explanation:

¡Hola!

En este caso, dado en química se conocen las estructuras de Lewis como representaciones gráficas de como los elementos están enlazados entre sí, debemos tener en cuenta que estos enlaces se forman entre los electrones de valenciam, los cuales son utilizados para su representación. Se sabe que los electrones de valencia son representados con puntos alrededor del elemento a través de puntos que se unen entre sí y son el número de electrons en la capa más externa de los elementos en cuestión; por ejemplo, cloro tiene 7 electrones de valencia, azufre tiene 6, hidrogeno 1, carbono 4 y así sucesivamente.

¡Saludos!

1pt Which particle is a neutron most equal to in mass?
My name is Ann [436]

Answer:

c. a proton

Explanation:

A neutron is most equal in mass to a proton.

A neutron is a subatomic particle without any charges on them.

A proton is a subatomic particle with a positive charge.

  • the mass of a proton and neutron are the most similar in an atom.
  • the mass of a proton is 1.67 x 10⁻²⁷kg
  • So also is the mass of a neutron
  • the mass of an electron is 9.11 x 10⁻³¹kg

rusak2 [61]

Answer:

The nucleus in eukaryotes and the cytoplasm in prokaryotes

Explanation:

The nucleus is the largest organ in a eukaryotic cell which is responsible for the control of the cell activities based on processing of received information and cell administration. The nucleus is therefore, known as the cell cell control center for regulating the metabolism of the cell and administers the cell and cellular information with which proteins are made

The nucleus contains nucleolus and it is the store for the chromosomes, which play an important role in genetics, related to the synthesis and replication of DNA and RNA

The functions of the nucleus are spread out through out the cytoplasm of prokaryotes.
