Hello,
Haber process is defined as the widely acknowledged productive process of ammonia by the reaction:
Which is carried out in gaseous phase. Thus, by means of the Le Chatelier's principle, it is possible to know that its standard enthalpy of reaction is -45.90 kJ/mol (NIST webbook) for which it is an exothermic chemical reaction, for that reason less ammonia will be produced at high temperature, nonetheless, the temperature should not be too low since the reaction rate significantly decrease, therefore, the optimum found temperature is 450 °C.
Moreover, since there are more moles (3+1=4) at the reactants and less moles at the products (2), increasing the pressure of the reaction increases the yield of ammonia, nonetheless, higher pressures involve the purchasing of more expensive equipment to withstand the high-pressures, for that reason, the best found pressure has been set as 200 atm.
Best regards.
A magnet is a special force that attracts other materials
Answer:
A little boy is playing with a plastic water bottle. He blows air into the bottle to make a whistling sound. Then, he wedges a plastic ball into the bottle to make a rattle. But the ball is too big—it gets stuck in the mouth of the bottle! The little boy panics and runs to his big brother for help.
Luckily, his older brother just studied the principle of Boyle's law. Based on what he learned, how will he get the ball out of the bottle?
by placing the bottle in the freezer to decrease the mass of the air inside the bottle
by pushing down on the bottle to decrease the temperature of the air in the bottle
by placing the bottle in the freezer to increase the air pressure inside the bottle
by pushing down on the bottle to increase the air pressure inside the bottle?
Explanation:
You will need to heat the bottom of the bottle to make gas build up than the ball will pop out.
Answer:
3.25 × 10²⁴ molecules of water
Explanation:
Step 1: Write the balanced equation
3 PbO + 2 NH₃ → 3 Pb + N₂ + 3 H₂O
Step 2: Calculate the moles of water formed from 3.60 moles of ammonia
The molar ratio of NH₃ to H₂O is 2:3. The moles of water formed are 3/2 × 3.60 mol = 5.40 mol
Step 3: Calculate the molecules in 5.40 moles of water
We will use Avogadro's number: 6.022 × 10²³ molecules/mol.
5.40 mol × 6.022 × 10²³ molecules/mol = 3.25 × 10²⁴ molecules
