Hello!

Complete ionic equations separate the equations into ion forms. Weak electrolytes and solids (precipitate) are exempt from this rule.

Net ionic equations are complete ionic equations but the ions that don't form as a precipitate are left out of the equation.

Anything cancelled out from the complete ionic equations are considered the spectator ions.

Looking at the equation, there are no weak electrolytes (you might have not covered this material yet), and the only precipitate in the solution is V(OH)_3 .

1. What is the complete ionic equation?

Let's ionize the equation. Make sure all the atoms are correspondent with their coefficients. Don't forget their charges.

3Li^+(aq)+3OH^-(aq)+V^3^+(aq)+3Cl^-(aq)= 3Li^+(aq)+3Cl^-(aq)+V(OH)_3(s)

Label every ion as (aq), and check the periodic table for their charges. Even without looking for V, we know that it is a 3+ charge since there are 3 chlorines attached to it.

2. What is the net ionic equation?

Get rid of all of the ions that don't do anything. Consider them lazy if they don't precipitate or form a solid. In this case, anything other than V and OH should be removed since they don't react. Think of it as cancelling out the ions that are still ions both sides.

V^3^+(aq)+3OH^-(aq)=V(OH)_3(s)

3. What are the spectator ions?

Spectator ions are the cancelled out ions from the previous problem.

3Li^+(aq)~, 3Cl^-(aq)

Answer from: Quest

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

Answer from: Quest

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
