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
Answer:
In gamma-ray astronomy, gamma-ray bursts are immensely energetic explosions that have been observed in distant galaxies. They are the brightest and most energetic electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several hours. b

Answer:
3189.07Pa
Explanation:
The conversion of 23.92mmH to Pa can be achieved in the following way:
760mmHg = 101325Pa
23.92mmHg = (23.92x101325)/760 = 3189.07Pa
What is the element with 7 protons? They probably also have 7 neutrons. Just a ball park figure guess.
