Why would knowing the molar volume of a gas be important? Why is 22.4 liters called the molar volume of a gas? I have 5.6 X 10 (24) molecules of Helium gas to fill balloons at a ballgame. If …

A nebula. A nebula is an interstellar cloud of dust, hydrogen gas, helium gas and other ionized gases where stars are created.

A helium balloon with an internal pressure of 1.00 atm and a volume of 4.50 L at 20.0°C is released. What volume will the balloon occupy at an altitude where the pressure is 0.600 atm …

Well how many atoms are in 20 dozen helium atoms? I make this quantity 240 atoms.... Here you specify 20.0*mol helium atoms.... And a mole SPECIFIES 6.022xx10^23 individual particles. …

The "Noble Gases" are Group VIII (or 18) of the Periodic Table: helium; neon; argon; krypton; xenon. Another name for this Group are the "Inert Gases". Given the full valence shell of this …

Explanation: When you use a helium balloon, why don't you have to heat the gas in the canopy? Dihydrogen is even lighter than helium (it's certainly cheaper); why don't we use dihydrogen …

Helium is unable (really) to attract other electrons, so doesn't really have an electronegativity. Since it has a full outer shell, it cannot bond, so its electronegativity is irrelevant. Fluorine has …

What would be the volume of 6.00 g of helium gas at STP? Rank each of the elements in order of decreasing ionization energy: S, Cl, Br? (Justify) Write the equilibrium-constant expression for …

May 31, 2017 · The eighth planet is Neptune. Neptune is the eighth and currently the furthest planet from the Sun. Even though Neptune is called an ice giant it isn't made of ice. In fact it is …

How does temperature affect the movement of atoms and molecules? How are real gases different from ideal gases? Why do helium filled balloons deflate over time faster than air-filled …
