Describe the evidence for Mercury having a molten iron core

Chemistry
1 answer:
Advocard [28]3 years ago
6 0
Scientists used the calculated density to determine that Mercury holds a large metallic core. Radar images taken from Earth revealed that the core is molten liquid, rather than solid. Mercury's core has more iron than any other planet in the solar system.

Which scatterplot shows the correct division for using the Divide-Center of Data method to draw the trend line?
nlexa [21]

The appropriate scatter plot that depicts the correct division for using Divide center to draw trend line is the plot D.

<h3>What are Scatter plots?</h3>

Scatter plots are used to show how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the position of which is determined by the values of the columns set on the X and Y axes. Scatter plots are graphs that show the relationship of two variables in a data set. It is a two-dimensional plane or a Cartesian system that represents data points.

In order to draw a trend line correctly, divide the points using the divide center method. The dividing vertical line must be drawn at the midpoint (a position where the number of data points to the left and right of the vertical line is equal).

Only option D has a vertical line dividing the 6 data points into two equal portions when the options are evaluated based on this condition.

The diagram is attached.

Which of the following required Bohr's model of the atom to need modification ? A. Energies of electrons are quantized. B. Quant
ki77a [65]

Answer:

Electrons do not follow circular orbits around the nucleus

Explanation:

Bohr's model of the atom is a combination of elements of quantum theory and classical physics in approaching the problem of the hydrogen atom. According to Neils Bohr, stationary states exist in which the energy of the electron is constant. These stationary states were referred to as circular orbits which encompasses the nucleus of the atom. Each orbit is characterized by a principal quantum number (n). Energy is absorbed or emitted when an electron transits between stationary states in the atom.

Sommerfeld improved on Bohr's proposal by postulating that instead of considering the electron in circular orbits, electrons actually orbited around the nucleus in elliptical orbits, this became a significant improvement on Bohr's model of the atom until the wave mechanical model of Erwin Schrödinger was proposed.
