When the compound BaCl2 forms , what happens to the Ba and Cl ions
2 answers:
Answer : The correct answer is Ba²⁺ and Cl⁻ ions .
This can be explained using Solubility concept .
Solubility is defined as property referring to ability of a substance , SOLUTE , to dissolves in a SOLVENT . It is measured at maximum amount of solute that dissolves in solvent as equilibrium .
Solubility of any compound can be checked using Solubility Rule ( Image ).
BaCl₂ is salt of Chloride . Since the solubility rules says that salts if chlorides are soluble , Hence BaCl₂ is also soluble .
SO when BaCl₂ forms in aqueous solution , it again dissociates to forms ions since it is soluble in aqueous solution . It produced one Ba²⁺ ion and two ions of Cl⁻ .
The BaCl₂ dissociates as follows :
Hence even BaCl₂ forms but it remain as dissociated ionic form as Ba²⁺ and Cl⁻ ions.

Answer:
A
Explanation:
Let's illustrate this; see the attachment.
We see that Mrs. Jacobson is pushing to the right with a force of 100 N and there is another opposite force pushing with a force of 15 N. Since these are in opposite directions, we can say that the force opposite to Mrs. Jacobson is pushing the fridge -15 N to the right (instead of 15 N to the left).
The net force would then be:
100 N + (-15 N) = 85 N to the right
The answer is A.
