Answer:
The balanced equation would be N2 + 3H2 --> 2NH3
Explanation:
Answer : 0.026 moles of oxygen are in the lung
Explanation :
We can solve the given question using ideal gas law.
The equation is given below.
We have been given P = 21.1 kPa
Let us convert pressure from kPa to atm unit.
The conversion factor used here is 1 atm = 101.3 kPa.
V = 3.0 L
T = 295 K
R = 0.0821 L-atm/mol K
Let us rearrange the equation to solve for n.
0.026 moles of oxygen are in the lung
In condensation, matter changes from a gas to a liquid. All matter is made of tiny moving particles called molecules. Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.
Answer:
3.8 cm
Explanation:
Given data
- Initial pressure (P₁): 3.2 atm
- Initial volume (V₁): 65 cm³
Volume of a sphere: V = 4/3 × π × r³ = 4/3 × π × (2.5 cm)³ = 65 cm³
- Initial temperature (T₁): 5.4°C + 273.15 = 278.6 K
- Final pressure (P₂): 1.0 atm
- Final temperature (T₂): 25.0°C + 273.15 = 298.2 K
We can find the final volume using the combined gas law.
The final radius of the bubble is:
V = 4/3 × π × r³
223 cm³ = 4/3 × π × r³
r = 3.8 cm
I believe it's electro-magnetic variation
