The answer is two atoms of carbon.
Answer:
The identity of the gas is Cl₂ (chlorine)
Explanation:
STP conditions are:
1 atm → Pressure
273.15 K → T°
So, we must use the Ideal Gas Law to get the moles.
Before that, we will think density as data where 3.164 g of diatomic gas are contained in 1 L of volume.
P.V = n . R . T
1 atm . 1 L = n. 0.082 L.atm/mol.K . 273.15K
1 L.atm / (0.082 L.atm/mol.K . 273.15K) = n
0.0446 mol = n
This quantity of diatomic gas, are 3.164 g so the molar mass will be:
Mass / mol = molar mass
3.164 g / 0.0446 mol = 70.9 g/m
The element (a diatomic molecule), which has that molar mass in the periodic table is the Cl₂.
1 Cl = 35.45 g/m
Cl₂. = 70.9 g/m
Yes because a chemical reaction will change the weight and mass of an object but all the molecules did not dissapear. they were just formed into a different substance, wether that being a solid, liquid, or gas.
While ethanol being an alcohol does have a direct O−H connection. Hence, ethanol has intermolecular hydrogen bonds. Therefore, more stroger physical bonds have to be destroyed in ethanol, than in acetone. Hence, acetone evaporates faster than ethanol inspite of having higher surface tension.
<h3>What is Vapor pressure ?</h3>
The pressure that a vapour exerts on the condensed phases (solid or liquid) in a closed system when they are in thermodynamic equilibrium with one another is known as vapour pressure (or equilibrium vapour pressure).
- It is significant to remember that when a liquid boils, the pressure of its vapour equals the atmospheric pressure. For instance, the vapour pressure of water when it boils at sea level is 1 atmosphere because the surrounding pressure is also 1 atmosphere.
