The atom will gain 3 electrons
<h3>Further explanation</h3>
Valence electrons are electrons that are used to bond which are located in the outer shell of the atom
The electron configuration of N :
[He] 2s² 2p³
This configuration shows that there are 5 valence electrons in the outer shell of the N atom
So based on the octet rule, the N atom will bind 3 more electrons to make it stable
An example is the formation of covalent (triple) bonds in the formation of N2 molecules
I believe C is the balanced equation.
<span>Scientific hypotheses, theories, and laws are all means to explain a scientific phenomenon. A hypothesis is a testable observation. There must be a way to test your "if X then Y" statement. A theory, while not always a linear shift from a hypothesis, is an established idea about why something happens, as verified by experimentation. A law is a proven fact about what happens and why.</span>
Answer:
Mass = 36.38 g
Explanation:
Given data:
Mass of hydrogen = 30.0 g
Mass of nitrogen = 30.0 g
Theoretical yield of reaction = ?
Mass of ammonia = ?
Chemical equation:
N₂+ 3H₂ → 2NH₃
Number of moles of N₂:
Number of moles = Mass /molar mass
Number of moles = 30 g / 28 g/mol
Number of moles = 1.07 mol
Number of moles of H₂:
Number of moles = Mass /molar mass
Number of moles = 30 g / 2g/mol
Number of moles = 15 mol
Now we will compare the moles of NH₃ with hydrogen and nitrogen .
H₂ : NH₃
3 : 2
15 : 2/3×15= 10 mol
N₂ : NH₃
1 : 2
1.07 : 2 × 1.07= 2.14 mol
The number of moles of NH₃ produced by nitrogen are less it will be limiting reactant.
Mass of ammonia:
Mass of NH₃ = moles × molar mass
Mass =2.14 mol × 17 g/mol
Mass = 36.38 g
Kinetic energy because kinetic energy is the form of movement or it could be mechanical energy
