Magnesium oxide (MgO) is an ionic compound formed by the transfer of electrons from magnesium to oxygen, resulting both atoms being electronically stable. Its properties include having high melting and boiling points, being a good electrical insulator but a thermal conductor.
Magnesium oxide, often referred to as 'MgO,' is a compound comprised of two different elements: magnesium and oxygen. It is a type of ionic compound because it is formed by a metal, magnesium, and a non-metal, oxygen. This creation occurs through a process called ionic bonding, where the magnesium atom effectively donates two electrons to the oxygen atom. Consequently, both atoms achieve a stable electronconfiguration.
In its solid state, MgO takes a form of a white, crystal-like substance. It's generally known for its high melting and boiling points, reflecting the strong ionic bonds in oxide structure. Furthermore, the compound stands out for being a good electrical insulator, but a thermal conductor.

The distance from Santa Maria to Los Alamos, which is 16.25 miles, would be approximately 2615178.4 centimeters when converted using the conversion factor of 1 mile = 160934.4 cm.
In order to convert the distance from miles to centimeters, you need to use conversion factors. We know that 1 mile is equivalent to approximately 160934.4 centimeters. Therefore, to find the distance from Santa Maria to Los Alamos in centimeters, you would multiply the number of miles by the number of centimeters in a mile.
The calculation would look like this:
16.25 miles * 160934.4 cm/mile = 2615178.4 cm
So, the distance between Santa Maria and Los Alamos is approximately 2615178.4 centimeters.

Answer:
The atomic mass is the weighted average of all the naturally occurring isotopes of the element.
Explanation:
A. The atomic mass is the weighted average of all the naturally occurring isotopes of the element. YES. Since there can be several different isotopes of the same element, the weighted average is used in the periodic table to reflect the likely composition of a random sample.
B. The atomic mass is determined by the number of protons in the nucleus. NO
C. The atomic mass is a whole number, but it appears as a fraction due to rounding in the periodic table. NO.
D. The atomic mass is a decimal number because it represents the total number of electrons in the atom. NO.
the change in carbon dioxide levels in the atmosphere
B.
the composition of the sun
C.
the red-shift of distant galaxies
D.
the magnetization of rocks on the ocean floor
Energy emitted from stars is the result of fusion.
Fusion is a process where two or more atoms combined together to form a new molecule.
As in the question it is stated that Luminosity is the amount of energy emitted by a star each second is true, because of the fusion of hydrogen atoms to helium atom and high amount of energy is released in the form of light. And Stars radiate light over a broad range of frequencies in the electromagnetic spectrum, from the low energy radio waves to high energy gamma rays.
Hence, due to fusion energy is emitted from stars in the luminous.
