Is Ar a atom or molecule?
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
What is the abbreviation for Arkansas?
AR Many people believe it is AK, but that is Alaska.
How many protons are in the nucleus of Ar atoms?
It depends on the identity of the atom. For example, Hydrogen has one proton, but Helium has two.
How many moles of argon gas contain 7.52 x 1022 Ar atoms?
To find the number of moles of argon gas, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms/mole. Divide the number of argon atoms by Avogadro's number: [ \text{moles of Ar} = \frac{7.52 \times 10^{22} \text{ atoms}}{6.022 \times 10^{23} \text{ atoms/mole}} \approx 0.125 \text{ moles} ] Thus, there are approximately 0.125 moles of argon gas.
What type of bond is Ar?
Argon (Ar) is a noble gas and does not typically form chemical bonds with other elements. It exists as single atoms in its natural state.
How many argon (Ar) atoms are there in 1.5 102 g of argon?
To find the number of argon atoms, we first need to determine the molar mass of argon: 39.95 g/mol. Next, we convert the given mass to moles using the molar mass: 1.5 x 10^2 g / 39.95 g/mol = 3.75 mol. Finally, we use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms: 3.75 mol x 6.022 x 10^23 atoms/mol ≈ 2.26 x 10^24 argon atoms.
