<h3><u>Answer and explanation</u>;</h3>
- To balance the charges of ions the number of electrons lost is equal to the number of electrons gained. The overall net charge must be zero.
- The number of ions needed to accomplish this is represented by the subscripts.
- For any given ionic compound, the product of the charge on the ion (or multiatomic ionic group) times the subscript of the ion will give a total charge of zero when all ions are considered.
For examples: NaCl Na = +1 Cl = -1 total is zero
Answer:
The number of protons also determines the identity of the element. ... Since the atom is electrically neutral, the number of electrons must equal the number of protons.
Answer:
the answer is O²- hopefully
The reaction is not at equilibrium and it is in the forward direction.
a.
Given,
[N₂] = 0.910 mol / L
[H₂] = 0.3 mol / L
[NH₃] = 0.0081 mol / L
K = 9.83 x 10⁻²
The balanced chemical equation for the given reaction is,
N₂(g) + 3H₂(g) ⇄ 2NH₃(g)
The formula of equilibrium constant is given by,
K = [NH₃]² / [N₂] [H₂]²
9.83 x 10⁻² = [(0.0081)² ]/ [0.910 × (0.3)²]
⇒9.83 x 10⁻² = (0.00006561) / (0.0819)
⇒9.83 x 10⁻² = 0.0008010989
⇒0.00983 = 0.0008010989
LHS ≠ RHS
Hence, the reaction is not at equilibrium.
b.
The reaction is in forward direction.
