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:
Explanation:
<em>First calculate how many moles of O2 you have. O is 16g/mole, so O2 is 32g/mole. 50/32 = 1.5625 moles. 1 mole of any gas at stp is 22.4 liters.</em>
<em>1.5625 × 22.4 = 35 liters.</em>
