D) reacts with oxygen
All other are physical properties.
Answer : The missing part is,
Explanation :
Nuclear fission : It is a process in which a heavy nuclei absorbs a neutron, they split or fission into two small nuclei and 3 neutrons.
Atomic number of Cf = 98
Atomic mass of Cf = 252
Atomic number of Te = 52
Atomic mass of Cf = 136
Atomic number of unknown element = [(252 + 1) - (136 + 3)] = 114
Atomic mass of unknown element = 98 - 52 = 46
So, the unknown element is, palladium (Pd)
The complete nuclear fission of a californium atom will be,
Hence, the missing part is,
They aren’t the same. Velocity is both speed and direction. For example: 5 mph south
Answer:
9.79740949850 moles
Explanation:
- 1 mole = Avogardo's Number <<6.022 E 23 <<particles, atoms, etc.>>
- This problem can be solved using dimensional analysis by multiplying atoms (5.9E24 atoms) by (1) mole and then dividing the number by Avogardo's number (6.022 E 23 atoms).
- Note: E = * 10
