<span>Answer:
M in this equation is molar mass. If A is He and B is O2 then MA = 4 g/mol and MB = 32 g/mol
rate A = 1.5L/24hr rate B = 1.5L/?hr and rateA/rateB = ?/24</span>
Answer:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Explanation:
Mole percentage of nitrogen gas = 25 mole%
Mole percentage of hydrogen gas = 75 mole%
Average molecular weight of the mixture:

Rate of flow of the stream = 3000 kg/h
Mass of stream in 1 hour = 3000 kg = 3,000,000 g
Moles of stream :

Moles of nitrogen gas in 352,941.17 moles of stream be x


x = 88,235.294 mol
Mass of 8,823,529.4 mole of nitrogen gas:

The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Answer:
Ice melting is a physical change, and the mass of the substance remains the same.
Explanation:
Hello!
In this case, since the phase transitions from solid to liquid, liquid to gas, solid to gas and vice versa are physical changes by which the molecules change their arrangement, being close for solids, not so close, not so far for liquids and spread for gases, the more the energy added, the more separated the molecules they turn out.
However, when the appropriate amount of energy is added, the mass of the changing substance remains the same and the change takes place, it means that the correct answer, when ice melts, is ice melting is a physical change, and the mass of the substance remains the same.
Best regards
Momentum and Kinetic Energy...They both are directly proportional to the
Mass and Velocity of the object and they are the only factors which
determine them.
Hope this helps!
