Answer:
v = 34.62 L
Explanation:
Given data:
Moles of H₂ = 2.50 mol
Temperature of gas = -20.0°C
Pressure of gas = 1.5 atm
Volume of gas = ?
Solution:
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
-20 + 273 = 253 K
Now we will put the values in formula.
1.5 atm × v = 2.50 mol ×0.0821 atm.L/ mol.K × 253 K
1.5 atm × v = 51.93 atm.L
v = 51.93 atm.L/1.5 atm
v = 34.62 L
The volume of hydrogen is 34.62 L.
Answer:
First oil well in the United States, built in 1859 by Edwin L. Drake, Titusville, Pennsylvania.
Answer is: Allena is correct. It is an element because it is only made of chlorine atoms.
A chemical element bonded to an identical chemical element is not a chemical compound since it is made from only one element and not from two different elements. Chlorine is molecule, but not compound.
