13000 liters, 0.000012 cm3 or ml or cc
The answer is by using chemical reactions.
Answer:
D alpha particles
Explanation:
Radioactive U-238 will decay into Thorium -232 by emitting alpha particles in the process of nuclear fission.
Nuclear fission is the radioactive decay process in which a heavy nucleus spontaneously disintegrates into two lighter ones and several other particles with a large release of energy.
U-238 → Th-232 + alpha particles + 2 neutrons + energy
This way the mass and atomic numbers are conserved;
Answer: The correct answer is option B.
Explanation:
- Ionic bond is formed when there is complete transfer of electrons from one element to another.
- Covalent bond is formed by the sharing of electrons between two elements.
- Metallic bond is formed when two metals combine together.
Electronic Configuration of Group VII-A :
This group require 1 electron to attain stable electronic configuration.
Electronic configuration of Group I-A :
This group will loose 1 electron to attain stable electronic configuration.
So, there will be complete transfer of electron from Group VII-A to Group I-A and hence, will form ionic bond between them.
Hence, the correct option is B.
Answer:
Kc of the reaction is 0.9375
Explanation:
Step 1: Data given
Moles of SO2 = 0.40 moles
Moles of O2 = 0.60 moles
Volume = 1.00 L
After the reactio we find 0.30 moles SO3
Step 2: The balanced equation
2 SO2(g) + O2(g) ⇔ 2SO3(g)
Step 3: Calculate Kc
Kc = [SO3]² / ([SO2]²[O2])
Kc = 0.30² / (0.40²*0.60)
Kc = 0.9375
Kc of the reaction is 0.9375
