Answer:
N₂
Explanation:
Using ideal gas law, you can find moles of the gas:
PV = nRT
PV / RT = n
<em>Where P is pressure (2.00atm); V is volume (4.0L), n are moles of gas; R is gas constant (0.082atmL/molK); and T is absolute temperature (30.0°C +273.15 = 303.15K)</em>
Replacing:
2.00atm×4.0L / 0.082atmL/molK×303.15K = n
<em>0.322 moles of gas = n</em>
The difference in mass is equal to mass of the gas. Knowing both moles and mass of the gas, molecular mass of the gas is:
9.1g / 0.322mol = <em>28.3g/mol</em>
As the gass is a diatomic gas, each atom weights 28.3/ 2 = <em>14.1g/mol </em>and this is the mass of nitrogen atom. Thus, the diatomic gas is<em> N₂</em>
Answer:
I don't understand what to do with this
The ionization energy or ionization potential is - the energy required to remove an electron from an element in its gaseous state.
Answer:
Hexane
Explanation:
Generally, leucine is hydrophobic in nature and it has a carbon-hydrogen side chain. Therefore, it is not advisable to use an hydrophobic solvent because the leucine zipper would interact with both the opposite alpha helix and the solvent. This will ultimately hinder the dimer creation. Thus, the best solvent which is the least polar in the list is hexane.
Omg I really really done know I just want point so ✌️ out
