Physics: Physics is more focused to finding the universal laws of general processes
Chemistry: Chemistry focuses more on details and specific phenomena, such as what is the boiling point of this substance and why.
Answer:
0.375 grams are needed to make 25 mL solution.
Explanation:
Mass of 
cuprous nitrate required to make 1 l of solution = 15 g.
1 L = 1000 mL
Mass of cuprous nitrate required to make 1000 mL of solution = 15 g
Mass of cuprous nitrate required to make 1 mL of solution:
Mass of cuprous nitrate required to make 25 mL of solution:
0.375 grams are needed to make 25 mL solution.
Functional groups are most identifiable through rational chemical formulas. In organic chemistry, the most basic functional groups include hydroxyl, carboxyl, carbonyl, ester, ether, and amino functional groups.
Al, Si, Mg
All other elements seem more necessary in life
Answer:
B. Emitting radiation as a result of unstable nuclei.
Explanation:
Radioactive by definition is "Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction". So we would assume that the answer would be B.
