The gamma ray is in science i guess try to look it up on google or something
Answer:
D. 91.0%
Explanation:
Hello,
In this case, for the given chemical reaction:

Next, since silver nitrate (molar mass 169.87 g/mol) is in a 2:1 molar ratio with silver sulfide (molar mass 247.8 g/mol), we compute its theoretical yield as shown below:

Next, we compute the percent yield as:

Hence, answer is D. 91.0%.
Best regards.
Fire, explosions, acid, fumes-take your pick here.
Answer : chemical reaction
Mixing an acid with a base is a common chemical reaction.
Answer:
The mass number is defined as the total number of protons and neutrons in an atom. The number of neutrons = mass number − atomic number.
