Answer:
1.44 atm
Explanation:
Step 1:
We'll begin by calculating the number of mole in 2,800,000 Liter of air.
I mole of air occupy 22.4L.
Therefore, Xmol of air will occupy 2800000L i.e
Xmol of air = 2800000/22.4
Xmol of air = 125000 moles
Step 2:
Determination of the pressure when the balloon is fully inflated .
This can be obtained as follow:
Number of mole (n) of air = 125000 moles
Volume (V) = 2800000 L
Temperature (T) = 120°C = 120°C + 273 = 393K
Gas constant (R) = 0.082atm.L/Kmol
Pressure (P) =.?
PV = nRT
Divide both side V
P= nRT/V
P= (125000x0.082x393) / 2800000
P = 1.44 atm
Therefore, the pressure of the air when the balloon is fully inflated is 1.44 atm
Answer:
false
Explanation
The chemical bonds were broken when creating the compound MgO.
Answer:
Oxygen, 43kg - Carbon, 16kg - Hydrogen, 7kg - Nitrogen, 1.8kg - Calcium, 1kg - Phosphorus, 0.78kg - Potassium, 0.14kg - Sulfur, 0.14kg - Sodium, 0.10kg - Chlorine, 0.095kg - and Magnesium, 0.019kg.
Answer: B, the gas is being squeezed out of the liquid.
Explanation: The gas does not want to be trapped inside of the liquid, so it is trying to force it’s way out. Therefore creating more pressure in the container or whatever the liquid is being held in.
Answer:
Energy level (n = 4), d subshell (l = 2)
Step-by-step explanation:
The number in 4d tells you the energy level of the subshell: n = 4.
The letter d gives you the secondary quantum number l.
Depending on its value, the letter gives you the shape of the orbital.
l = 0 corresponds to an s orbital (spherical)
l = 1 corresponds to a p orbital (dumb-bell shaped)
l = 2 corresponds to a d orbital (four four-leaf clovers + one that looks like a dumbbell with a doughnut around its middle)
