What was the main reason why Alfred Wegener's theory about the movement of the continents was dismissed in 1912?

His theory explained the Earth was expanding as the plates moved

He didn't know about plate tectonics to explain how the plates moved

His map of the ocean floor did not support his theory

His theory was the first to observe the continents fit together

Answers

Answer:

His map of the ocean floor did not support his theory

Explanation:

Alfred Wegner was a great scientistHe observed the plate tectonics of earth and described it in a theory.It was dismissed after viewing his ocean floor

Answer:

He didn't know about plate tectonics to explain how the plates moved

Explanation:

Wegener believed the continents had pushed through the ocean floor. However, he did not have a satisfactory explanation for how this happened. There was no known source of energy large enough to move continents through the sea floor. Also, although scientists had data about the interior of Earth from earthquakes, there were no clues in Earth's crust to show that the continents had broken through the sea floor. Given this lack of evidence to explain the mechanism of continental drift, scientists did not accept this idea.

which type of spectra would be produced by a hydrogen lamp?

Answers

Answer:  Emission spectra

The Emission spectrum can be separated into three types:

Line emission spectrum Continuous emission spectra.Band emission spectrum

What is a Hydrogen lamp?

A gas of hydrogen atoms will create an absorption line spectrum if it is between you (telescope+spectrograph) and a continuum light source, and also an emission line spectrum if considered from a distinguishable angle.

When The emission spectrum of atomic hydrogen has been divided into several spectral sequences, with wavelengths given by the Rydberg formula.

These experimental spectral lines are due to the electron-making transitions between two energy positions in an atom.

¿Qué relación existe entre la teoría del octeto de Lewis con los enlaces iónicos y
covalentes?

Answers

Por definición de enlace iónico, covalente y regla del octeto, la relación existente entre la teoría del octeto de Lewis con los enlaces iónicos y  covalentes es que dichos enlaces se producen con el objetivo de completar la última capa de electrones y adquirir estabilidad.

Enlace iónico

Por un lado, se produce un enlace iónico entre átomos metálicos y no metálicos, donde los electrones se transfieren completamente de un átomo a otro. Durante este proceso, un átomo pierde electrones y otro los gana, formando iones. Por lo general, el metal cede sus electrones formando un catión al elemento no metálico, que forma un anión.

Enlace covalente

Por otro lado, el enlace covalente es el enlace químico entre átomos donde los electrones se comparten, formando una molécula. Se establecen enlaces covalentes entre elementos no metálicos. El par de electrones compartidos es común a los dos átomos y los mantiene unidos.

Regla del octeto

En ambos casos se cumple con la regla del octeto, que establece que los átomos de los elementos se enlazan unos a otros en el intento de completar su capa de valencia con ocho electrones. Es decir que los átomos van a tender a ceder o compartir electrones para completar ocho electrones en la capa de valencia mediante un enlace iónico, covalente o metálico.

En otras palabras, el objetivo es tener la configuración electrónica del gas noble más cercano, teniendo así la última capa de electrones completa y adquiriendo estabilidad.

En resumen

En resumen, la relación existente entre la teoría del octeto de Lewis con los enlaces iónicos y  covalentes es que dichos enlaces se producen con el objetivo de completar la última capa de electrones y adquirir estabilidad.

Answers

A hydrogen energy system is made up of hydrogen production, transportation, storage, utilization etc. Whether a hydrogen-based energy system is environmentally cleaner than a fossil fuel system depends on the source of energy used to produce the hydrogen.

Hydrogen fuel cells often makes electricity by using  hydrogen and oxygen atoms. The hydrogen is said to reacts with oxygen across an electrochemical cell.

Hydrogen is known to carry some amount of energy carrier and can also deliver or store a large amount of energy. Hydrogen is often used in fuel cells to generate electricity, or power and heat.

In chemical compounds, covalent bonds form when -
a. the electronegativity difference between two atoms is very large
b. electrons are completely transferred between two metals
c. pairs of electrons are shared between two nonmetal atoms
d. two nonmetal ions are attracted to each other by opposite charges

Answers

Answer:

c. pairs of electrons are shared between two nonmetal atoms

Explanation:

Bonding between elements solely depends on their electronegativity. When there is large difference in electronegativity, those atoms form ionic bonds. Covalent bonds form when the difference is minimal, or none at all. When the difference between electronegativities is 0 or very close to 0, then they form pure covalent bonds, or nonpolar bonds. An example of this are diatomic molecules. Diatomic molecules are two of the same atom that form nonpolar covalent bonds because their electronegativy difference is 0, as they have the same electronegativity. When the electronnegativties have bit of difference, they form polar covalent bonds.
