Before proceeding, we should write the reaction equation to better understand what is happening:
2AgNO₃ + Na₂S → Ag₂S + 2NaNO₃
Now, we may apply the law of conservation of mass, due to which the total mass before a chemical reaction is equivalent to the total mass after a chemical reaction. Therefore:
Mass of silver nitrate + mass of sodium sulfide = mass of silver sulfide + mass of sodium nitrate
Mass of silver nitrate + 156.2 = 595.8 + 340
Mass of silver nitrate = 779.6 grams
Mostly the electrons will determine the reactivity
The answer is D)

Answer:
Look at the picture.
Explanation:
For planar anion point group is D3h. For trigonal piramidal point group is C3v.
On picture 2 and 3 are the tables for each point group. Irreducible representations its the horizontal rows in tables. Where you see x, y and z it's translation of p-orbitals. Where you see R - it's rotations.
