Answer:
The number of moles of nitrogen gas in the tennis ball is 0.0124 moles
Explanation:
Here we have the universal gas equation as
P·V = n·R·T
Where:
P = Pressure of the gas = 212 kPa
V = Volume of the gas = 0.148 L = 0.000148 m³
n = Number of moles
R = Universal gas constant = 8.3145 J / mol·K.
T = Temperature of the gas in Kelvin = 32 + 273.15 = 305.15 K
Therefore,
The number of moles of nitrogen gas in the tennis ball = 0.0124 moles.

Answer:
[N2] = 0.3633M
[H2] = 1.090M
[NH3] = 0.2734M
Explanation:
Based on the reaction of the problem, Kc is defined as:
Kc = 0.159 = [NH3]² / [N2] [H2]³
<em>Where [] are the equilibrium concentrations.</em>
The initial concentrations of the reactants is:
N2 = 1.00mol / 2.00L = 0.500M
H2 = 3.00mol / 2.00L = 1.50M
When the equilibrium is reached, the concentrations are:
[N2] = 0.500M - X
[H2] = 1.50M - 3X
[NH3] = 2X
<em>Where X is reaction quotient</em>
Replacing in the Kc equation:
0.159 = [2X]² / [0.500 - X] [1.50 - 3X]³
0.159 = 4X² / 1.6875 - 13.5 X + 40.5 X² - 54 X³ + 27 X⁴
0.268313 - 2.1465 X + 6.4395 X² - 8.586 X³ + 4.293 X⁴ = 4X²
0.268313 - 2.1465 X + 2.4395 X² - 8.586 X³ + 4.293 X⁴ = 0
Solving for X:
X = 0.1367. Right solution.
X = 1.8286. False solution. Produce negative concentrations
Replacing:
[N2] = 0.500M - 0.1367M
[H2] = 1.50M - 3*0.1367M
[NH3] = 2*0.1367M
The equilibrium concentrations are:
<h3>[N2] = 0.3633M</h3><h3>[H2] = 1.090M</h3><h3>[NH3] = 0.2734M</h3>

TPGS-750 M conducts reaction under lower temperature then the reactions carried out in organic solvents.
<h3>What is tpgs-750m ?</h3>
It is a chemical molecule of the second generation known as an amphiphile, with both hydrophilic and lipophilic qualities.
- In contrast to any other organic solvent, water is used for transition metal catalysed cross-coupling, making TPGS-750M a second generation surfactant with physical features that encourage this process.
- The hydrophilic portion of TPGS-750M, which is utilised in medicine, is made of Poly(ethylene glycol), and the hydrophobic portion is made of the vitamin E compound alpha-tocopherol.
