Answer:
b) volume per mol (10.237 L/mol) of the inlet gas less than of the outlet gas ( 24.378 L/mol ).
Explanation:
∴ R = 0.082 atm*L / K*mol...ideal gas constant
for entry:
T1 = 35°C + 273 = 308 K
P1 = 250 KPa * ( 0.009869 atm / KPa) = 2.467 atm
⇒(V/n)1 = (R * T1 ) / P1 = (( 0.082 atm*L / K*mol ) * (308 K )) / 2.467 atm
⇒ (V/n)1 = 10.237 L/mol ideal gas inlet
for the exit:
T2 = 35 °C + 273 = 308 K
P2 = 105 KPa * ( 0.009869 atm / KPa ) = 1.036 atm
⇒ (V/n)2 = (R * T2) / P2 = (( 0.082 * 308 )) / 1.036
⇒ (V/n)2 = 24.378 L/mol ideal gas outlet
Convection drives the earth's atmosphere and dictates the distribution of life in the world's oceans.
Answer:
C- A proton has about the same mass as a neutron .
Explanation:
In an atom such as a carbon atom, the masses of the proton and neutrons are the same.
The mass of the electrons is very negligible.
- Protons are the positively charged particles in an atom
- Neutrons do not carry any charges
- Both protons and neutrons have similar masses.
- They contribute the bulk of the mass of the atom.
- The electrons carry negative charges and they have negligible masses.
The mass of protons and neutrons are similar.
Answer:
I'm pretty sure this doesn't really connect with chemistry much but the answer should be <u>Schedule 1 </u> as stated by the Drug enforcement agency.
Answer:
Mass = 182.4 g
Explanation:
Given data:
Number of moles of Al₂O₃ = 3.80 mol
Mass of oxygen required = ?
Solution:
Chemical equation:
4Al + 3O₂ → 2Al₂O₃
Now we will compare the moles of aluminum oxide and oxygen.
Al₂O₃ : O₂
2 : 3
3.80 : 3/2×3.80 = 5.7
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 5.7 mol × 32 g/mol
Mass = 182.4 g
