is 7 cus the valance electron for sodium is Ne 3s1 and for chlorine is Ne 3s13p5
the correct answer is dissapate...but it is
not here so i think relativly the answer is destroy
Answer:
d properties
i took a test on this before
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
