Answer:
A
Explanation:
because It's the process by which atmospheric nitrogen is converted either by a natural or an industrial means to form of nitrogen such as ammonia.
The mass of air in the scuba tank is 841.614 g.
Using the ideal gas equation;
PV=nRT
P = pressure of the gas = 195 kPa
V = volume of the gas = 350 L
n = Number of moles of the gas = ??
R = molar gas constant = R = 8.314 J K-1 mol-1
T = temperature of the gas = 10 °C or 283 K
n = PV/RT
n = 195 * 350/8.314 * 283
n = 68250/2352.862
n = 29.00 moles
Number of moles = mass/molar mass
mass of air = Number of moles * molar mass
mass of air = 29.00 moles * 29g/mol
Mass of air = 841.614 g

Answer:
can you show the question so we can read it
Answer:
rotten egg smell
Explanation:
1,5-pentanedithiol ( C₅H₁₂S ) -
The compound have thiol as the functional group , and hence will show some characteristics of thiol group ,
The thiol group is a -SH group , they are also called mercaptan functional group .
The thiol group has a strong characteristic smell of rotten egg .
And hence , the compound 1,5-pentanedithiol ( C₅H₁₂S ) can easily be distinguished by its rotten egg smell .
