Answer:
Most radioactive materials decay and they mostly have a decay rate. The time it takes for half of a radioactive material to decay is called half life.
The 7 minute significance of half-life simply points to the total time it takes after which half of the radioactive material would have completely decayed,
Answer:
V = 0.5 L
Explanation:
Given data:
Moles of nitrogen = 2.23×10⁻² mol (0.0223 mol)
Temperature = 273 K
Pressure = 1 atm
Volume = ?
Solution:
PV = nRT
V = nRT / P
V = 0.0223 mol × 0.0821 atm. mol⁻¹. L . k⁻¹ × 273 K / 1 atm
V = 0.5 L
Answer:
its kinda you just need to simplify
Explanation:
what kind of question is this and idk
Answer: The Moon can sometimes appear in the sky during the daytime because it is the closest object to Earth, and because its orbital cycle means that sometimes it is brighter in the day than at night.
