How much space (volume) will 180.0 g of gold occupy?
Answers
Answer:
The space occupy by the 180.0 g of gold will be 9.32 cm³
Explanation:
Given data:
Mass of gold = 180.0 g
Volume occupy by the gold = ?
Solution:
The given problem will be solved through the density formula.
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
The density of gold from literature is 19.320 g/cm³
Now we will put the values in formula.
19.320 g/cm³ = 180.0 g/ V
V = 180.0 g/ 19.320 g/cm³
V = 9.32 cm³
The space occupy by the 180.0 g of gold will be 9.32 cm³.

Answer is Ca which is a metal.
Explanation: Milk is composed of many elements such as Calcium (Ca), Magnesium(Mg), Phosphorus(P), Potassium (K), Zinc(Zn) ans Selenium(Se). The major component present is Ca.
Calcium present helps in the formation of bones and teeth and maintaining it to keep healthy.
Elements which can loose electrons easily to obtain a stable configuration is called as a metal.
Calcium is a metal as it can easily loose 2 electrons to obtain a stable configuration.
Final answer:
Calcium, a metal, is the element in milk that makes it beneficial for health. It contributes to healthy bones, teeth, and the proper functioning of various body organs. Metalloids or semimetals like boron or silicon are not responsible for the health benefits of milk.
Explanation:
The element that makes milk good for health is Calcium. Calcium is a metal that is needed by the body for healthy bones, teeth, and proper function of the heart, muscles, and nerves. It is a representative metal that shows good conduction of heat and electricity. Milk is a primary source of Calcium, which is why it is considered beneficial for health.
On the other hand, elements such as boron, silicon, germanium, arsenic, antimony, and tellurium are considered metalloids or sometimes semimetals, which exhibit properties between metals and nonmetals. However, these are not the elements responsible for the health benefits of milk.

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.
Explanation:
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 paleoatmosphere refers to the Earth’s atmosphere in the geological past. The paleoatmosphere was dominated by nitrogen, carbon dioxide and methane. These gases are generated by the radioactive decay of Potassium. During this pre-biological atmosphere, it is thought to have been reducing, to have highly contained virtually no free oxygen, and virtually no argon. Therefore the major gases on this period are the Nitrogen and Carbon Dioxide.

This is the planetary model, which is so known nowadays, but it is not correct. The quantum model is based in orbitals (not orbits), which are regions around the nucleus where are the electrons, but they are not circling around the nucleus.
