How many atoms does a molecule of astatine vapor contain?
A molecule of astatine in vapor form may contain either one or two atoms, depending on its chemical structure.
What of an element is determined experimentally by bombardment of atoms in the vapor phase with a stream of electrons?
The answer that you wish to acquire is ionization energy. pretty sure at least. ;)
When a common fluorescent lamp is on the mercury vapor inside is actually in a which state?
When a common fluorescent lamp is on, the mercury vapor inside is in an excited state. When an electric current passes through the mercury vapor, it excites the mercury atoms, causing them to release ultraviolet light. This ultraviolet light then interacts with the phosphor coating on the inside of the lamp, producing visible light.
What kind of bond in AlCl3 have?
AlCl3 at high temperatres in the vapor phase is molcular, planar AlCl3. with polar covalent bonds. In the melt and at lower temperatures in the vapor phase it is dimeric, Al2Cl6 with two bridging Cl atoms ( Cl2AlCl2AlCl2), each aluminium atom is approximately surrounded by a tetrahedron of Cl atoms. in the solid the structure has each Al surrounded by 6 Cl atoms and the bonding is more ionic in nature. As the solid is heated just before it melts the electrical conductivity rises due to the presence of ions.
When hydrocarbons burn in plenty of oxygen the atoms rearrange themselves onto carbon dioxide and?
The compounds resulting from the total burning of hydrocarbons are carbon dioxide and water.
How many atoms does a molecule of astatine vapor contain?
A molecule of astatine in vapor form may contain either one or two atoms, depending on its chemical structure.
Why does water vapour have less density than dry air?
First you must understand "density." Density is the amount of atoms in a given volume. You can artificially create situations when there are more atoms in a given volume where the atoms are either "dry air" or "water vapor." But in ordinary situations, water vapor is mixed with what we call "air" and in ordinary situations, "dry air" has less water vapor in a given volume, so, people tend to say that water vapor is "heavy" or more "dense" than "air" or "dry air."
What is the relationship between water vapor air molecules temperature?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
Is water vapor a form of crystals?
No, water vapor is not a form of crystals. Water vapor is in its gaseous state, consisting of individual molecules of H2O that are not arranged in any particular crystal structure. Crystals are solid structures in which atoms or molecules are arranged in a repeating pattern.
Is air a vapor?
Air is a mixture of gases, not a vapor. Vapor refers to the gaseous state of a substance that is typically a liquid or solid at room temperature. However, water vapor is a component of air, along with nitrogen, oxygen, and other gases.
How many atoms are in 131.97 liters of water vapor at STP?
Use the ideal gas equation to get moles of water vapor. PV = nRT (1 atm)(131.97 L) = n(0.08206 L*atm/mol*K)(298.15 K) = 5.3939 moles H2O (6.022 X 10^23/1 mole H2O) = 3.2482 X 10^24 atoms of water vapor --------------------------------------------------------
That Na and Hg in vapour state exist as monoatomic molecules?
True. In their vapor state, both Na and Hg exist as monoatomic molecules, with Na being represented as Na and Hg as Hg. This is because in their gaseous form, both elements exist as individual atoms rather than diatomic molecules.
Is water vapor the same as hydrogen?
No, water vapor is a gas formed when water evaporates, while hydrogen is a colorless, odorless, and tasteless gas. Water vapor is composed of two hydrogen atoms and one oxygen atom, while hydrogen exists as individual hydrogen molecules.
What is water vapor made out of?
Water vapor is composed of individual water molecules in a gaseous state. These water molecules contain two hydrogen atoms and one oxygen atom bonded together. When water evaporates, it transitions from a liquid to a gas and becomes water vapor.
What elements make up water vapor?
Water vapor is composed of water molecules in a gaseous state, with each molecule consisting of two hydrogen atoms and one oxygen atom (H2O). When liquid water evaporates or solid ice sublimates, it forms water vapor.
What is the atomicity of a gas if it's vapor density is 28 and atomic weight is 14?
The atomicity of a gas can be determined by comparing its vapor density to its atomic weight. In this case, if the vapor density is 28 and the atomic weight is 14, the atomicity of the gas is 2. This means that each molecule of the gas consists of 2 atoms.
Does a cold object have more or less atoms?
A cold object does not have more or less atoms than a warm object. The temperature of an object does not affect the number of atoms it contains, as the number of atoms remains constant regardless of temperature.
