Answer:
The pressure inside the container is 6.7 atm
Explanation:
We have the ideal gas equation: P x V = n x R x T
whereas, P (pressure, atm), V (volume, L), n (mole, mol), R (ideal gas constant, 0.082), T (temperature, Kelvin)
Since the container is evacuated and then sealed, the volume of the body of gas is the volume of the container.
So we can calculate the pressure by
P = n x R x T / V
where as,
n = 41.1 g / 44 g/mol = 0.934 mol
Hence P = 0.934 x 0.082 x 298 / 3.4 L = 6.7 atm
Answer:
beryllium chloride
Explanation:
Therefore a compound made from beryllium and chlorine will be named beryllium chloride.
Answer:
I’m not a expert on it, but I think B or D
Explanation:
Answer:
(a) Density of the air = 1.204 kg/m3
(b) Pressure = 93772 Pa or 0.703 mmHg
(c) Force needed to open the door = 15106 N
Explanation:
(a) The density of the air at 22 deg C and 1 atm can be calculated using the Ideal Gas Law:

First, we change the units of P to Pa and T to deg K:

Then we have

(b) To calculate the change in pressure, we use again the Ideal Gas law, expressed in another way:

(c) To calculate the force needed to open we have to multiply the difference of pressure between the inside of the freezer and the outside and the surface of the door. We also take into account that Pa = N/m2.

51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
<h3>How to find the Number of moles ?</h3>
To calculate the number of moles use the formula
Number of moles = 
= 
= 1.9 mol
4NH₃ + 5O₂ → 4NO + 6H₂O
4 mol of NH₃ react with oxygen to given 6 mole of water.
So 1.9 mol of NH₃ produces = 
= 2.85 mol of water
Mass of water = Molar Mass of water × Number of moles of water
= 18 × 2.85
= 51.3 gram
Thus from the above conclusion we can say that 51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
