A chunk of sulfur has a volume of 8.33 cm3. What is the mass of this sulfur? (Density of sulfur = 2.07 g/cm3.)
Answers
Explanation:
equations to note:
density= mass/volume
mass= volume *density
volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
mass= 17.24g

What did Fermi mean when he said, "The reaction is self-sustaining"?
The reaction reached critical mass.
A spontaneous chain reaction had been accomplished.
The nuclear reaction was out of control.
The nuclear reaction could be controlled and maintained.
Answers
Answer:
The nuclear reaction could be controlled and maintained.
Explanation:
People had initiated a self-sustaining nuclear reaction--and then stopped it. He had released the energy of the atom's nucleus and controlled that energy.
Fermi's achievement in setting off the first self-sustaining nuclear chain reaction from his design of an atomic pile led to a new Age of the Atom. The controlled release of nuclear energy was now a reality
