The balanced equation for the above reaction is;
<span>2AgNO</span>₃<span> + BaCl</span>₂<span> ==> 2AgCl + Ba(No</span>₃<span>)</span>₂
stoichiometry of BaCl₂ to AgCl is 1:2
number of BaCl₂ moles reacted - 12.5 g / 208.23 g/mol = 0.06 mol
number of AgCl moles produced - 0.06 mol x 2 = 0.12 mol
Therefore mass of AgCl produced - 0.12 mol x 143.32 g/mol = 17.2 g
<h3><u>Answer</u>;</h3>
Cu2+, Zn2+, F-, and SO3^2-
<h3><u>Explanation</u>;</h3>
- Hydrolysis is a reaction of a substance or a compound with water.
- Anions such as Cl- and cations such as K+ and Ba2+ of strong acids and bases to not hydrolyze.
- For example; KOH and Ba(OH)2 are strong bases, and HCl is a strong acid.
- All the other ions will have a hydrolysis reaction with water and establish an equilibrium;
Cu2+ + HOH ↔ CuOH^+ + H+
Zn2+ + HOH ↔ZnOH^+ + H+
F- + HOH ↔ HF + OH-
SO3^2- + HOH ↔ HSO3^- + OH-

<span>Now consider a low pressure area on a disk as shown below.A parcel of air at point A would move toward the center of the low pressure area. That movement would take it farther away from the center of the disk and therefore it would move to the west. A parcel of air at B would move toward the center of the low pressure area which would also take it closer to the center of the spinning disk where its speed is greater than the surrounding points. It would appear to move to the east. With A moving to the west and B moving to the east the line from A to B is rotating counterclockwise.</span>
Answer:
Explanation:
N = Final mass of atom = 125 g
= Initial mass of atom = 16000 g
t = Time taken = 163.24 days
= Half life
We have the relation
The half life of the atom is .
