Argon

Argon is a noble gas and exists as individual atoms in a face-centered cubic (FCC) crystal lattice structure at low temperatures. At higher temperatures or pressures, it can adopt a body-centered cubic (BCC) structure.

To determine the number of moles of argon gas required to fill a volume of 116.7 L, we first need to convert the volume to liters. Using the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature, we can calculate the number of moles. Given that argon gas is at STP (standard temperature and pressure), we can use the standard values of 1 atm for pressure and 273 K for temperature.

Argon is commonly used in various industries for welding, metal production, and as an inert atmosphere in laboratories. It is also used in certain types of light bulbs, such as incandescent and fluorescent bulbs, to prevent oxidation of the filament. Argon is also used in the food industry for packaging perishable goods to extend their shelf life.

To find the number of argon atoms, we first need to convert mmol to moles by dividing by 1000. Then we use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of argon atoms.

Therefore, number of argon atoms = (7.66 x 10^5 mmol / 1000) x 6.022 x 10^23 atoms/mol

The volume percentage of argon in a gaseous mixture can be calculated using the ideal gas law equation, where the volume percentage of argon would be the volume of argon divided by the total volume of the mixture times 100.

The atomic number of argon is 18, which means it has 18 protons in its nucleus. The mass number of argon is 40, which is the sum of protons and neutrons in its nucleus.

Ca2+ is one of them

This is because the mass number of Argon (which is 18) lost 2 electrons (which has a negative charge). Without the impedance of the negative charge, Argon's mass number becomes 20 (instead of 18) and it acts like Calcium (which has the mass number of 20).

You can probably figure out the rest of them from the above.

Argon is a noble gas and is considered to be chemically inert, so it does not typically form ions. This is because its electron configuration is stable with a full outer electron shell, making it unreactive.

Not just the two but along with hydrogen, yes.

One limitation of argon-argon dating is that it requires the sample to have undergone a process of resetting, which may not always be the case. Additionally, the technique can be complex and expensive to use, making it less accessible for some researchers.

Argon is formed through the radioactive decay of potassium-40 in the Earth's crust. Potassium-40 undergoes a series of decay reactions, ultimately producing argon-40 as a stable end product. This process occurs over millions of years and is responsible for the presence of argon in the Earth's atmosphere.

Yes, neon and argon gases can change from a liquid state to a gas state when heated to their respective boiling points. Neon boils at -246.1°C and argon boils at -185.85°C. Heating them above these temperatures will cause them to change into a gas.

You just get a gas mixture of argon and hydrogen. Being less dense, the hydrogen will rise above the argon.

A solution with a percent by volume of 0.038 contains 0.038 liters of solute dissolved in 100 liters of solution. This means that 0.038% of the total volume is the solute.

Argon is a naturally occurring, inert gas that is non-toxic and non-reactive, so it is not considered an environmental concern. It makes up about 1% of Earth's atmosphere and is primarily used in industrial applications, such as welding and electronics manufacturing.

Argon, a noble gas, typically does not form ions because its outermost energy level is full. This stability makes it hard for argon to lose or gain electrons to form charged ions.

Argon is an inert gas with a full outer electron shell, so it does not typically form compounds with other elements. However, it can mix with other gases to form mixtures, such as in industrial processes or in the atmosphere.

There are 18 protons in each atom.

Argon is a noble gas that is odorless and colorless. Therefore, it has no distinct smell.

Yes, argon boils at a higher temperature than helium. Argon boils at -185.86°C whereas helium boils at -268.9°C.

When helium and argon are mixed together, they form a homogeneous mixture known as a gas blend. The properties of the gas blend will depend on the ratio of helium to argon in the mixture. Helium is lighter than argon and less soluble in liquids, so it tends to rise to the top of the mixture when not in a pressurized container.

Argon is a noble gas, which means it is non-reactive and typically does not form compounds with other elements. Its outer electron shell is full, making it stable and unreactive.

Argon is considered a nearly ideal gas under many conditions due to its low reactivity and monatomic structure, which leads to minimal intermolecular interactions. However, at extreme conditions of high pressure or low temperature, deviations from ideal gas behavior may occur.

The number is Avogadro's number, 6.0221409 *10^23

William Ramsay discovered argon in 1894 by isolating it from a sample of air. He separated the various components of air using a process of fractional distillation and identified a previously unknown gas, which he named argon.
