Answer:
Explanation:
4NH₃ + 3O₂- --> 2N₂ + 6 H₂O
4 mole 3 moles 2 moles 6 moles
4 moles of NH₃ reacts with 3 moles of oxygen
1.37 moles of NH₃ reacts with 3 x 1.37 / 4 mols of oxygen
corresponding amount of O₂ = 3 x 1.37 / 4 mols
= 1.0275 moles
corresponding amount of N₂ = 2 x 1.37 / 4 moles
= .685 moles
corresponding amount of H₂O = 6 x 1.37 / 4 moles
= 2.055 moles
Given amount of product N₂ = 3.82 moles
corresponding amount of NH₃ = 4 x 3.82 / 2 moles
= 7.64 moles
corresponding amount of O₂ = 3 x 3.82 / 2 moles
= 5.73 moles
corresponding amount of H₂O = 6 X 3.82 / 2 moles
= 11.46 moles .
Conductivity is a physical property
Odor is also a physical property
Answer:
1. Alpha particles consist of two protons and two neutrons.
Explanation:
Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.
AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;
Number of protons = 2
Number of neutrons = Mass Number - Atomic Number = 2
The correct option is option 1.
<span>While the Gilded Age was very active in terms of political voting turn out from the public, this was not by virtue of a purely innocent act. Political parties managed to get large voter turnouts because they would use corruption as a bargaining tool. They would give out jobs to people in return for their votes.</span>
