Two is wrong the rest are right
a. chain reaction
Explanation:
In a fission, a chain reaction is one where a neutron embeds itself in the nucleus of an U-235 atom and causes it to break apart. After this, more neutrons are created. The neutrons carry on the cycle by starting the fission process over and over again.
Chain reactions typifies most nuclear reactions taking place in the nucleus of an atom.
They are repeated loops that takes place until an atom reaches it state of stability.
- They are not exclusive to fission reactions alone.
- Chain reactions also takes place during nuclear fusion
- In fusion two atoms combines to produce a single nuclide.
- The steps goes on and on
- This why the sun keeps burning and bursting with energy

Answer:
We mostly use Kilograms and grams to measure mass =)
Explanation:
Answer:49.3
Explanation:4.1j/g c * 25g * (t2-45c)=455j
T2-45c = 455j/4.1j/g c * 25g
455/104.6
45+4.3= 49.3 celsius
Answer:
Mass = 0.61 g
Explanation:
Given data:
Pressure of neon gas = 720 mmHg
Temperature = -15.0°C
Volume = 760 mL
Mass of neon gas = ?
Solution:
720 mmHg = 720/760 = 0.95 atm
-15.0°C + 273 = 258 K
760/1000 = 0.76 L
PV = nRT
n = PV/RT
n = 0.95 atm ×0.76 L/ 0.0821 atm. L. k⁻¹.mol⁻¹× 258 K
n = 0.722 atm. L/ 21.2 atm. L. mol⁻¹
n = 0.03 mol
Mass of neon:
Mass = number of moles × molar mass
Mass = 0.03 mol × 20.2 g/mol
Mass = 0.61 g
