Answer:
The volume of ammonia produced by 4.2 L of hydrogen and excess nitrogen is 2.8 L.
Explanation:
Given data:
Volume of H₂ = 4.2 L
Volume of NH₃ produced = ?
Solution:
First of all we will write the balance chemical equation:
N₂ + 3H₂ → 2NH₃
Hydrogen is limiting reactant and volume ratio is,
H₂ : NH₃
3 : 2
4.2 : 2/3 × 4.2 = 2.8 L
The volume of ammonia produced by 4.2 L of hydrogen and excess nitrogen is 2.8 L.
The coordination number (C.N.) is 6 and oxidation number (O.N.) is +4 of the metal atom.
C.N. = 6; O.N. = +4
<h3><u>
What </u><u>is Co-ordination number ?</u></h3>
- The coordination number, also known as ligancy, of a central atom in a molecule or crystal in chemistry, crystallography, and materials science refers to the quantity of atoms, molecules, or ions bound to it.
- A ligand is the ion, molecule, or atom that surrounds the center ion, molecule, or atom.
- The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.
<h3><u>What is Oxidation number ?</u></h3>
- The total number of electrons that an atom acquires or loses to establish a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.
- Each atom involved in an oxidation-reduction reaction has an oxidation number that represents how many electrons it may take, give, or share.

Answer:
C. The particles move more slowly but stay far apart.
Explanation:
Abuse of dopamine have been linked to the neurotransmitter dopamine.
When an atom has an equal number of electrons and protons it has an equal number of negative charge (the electrons) and positive electric charges (the protons). The total electric charge of the atomic is therefore zero
