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.
Explanation:
the base in this equation is KOH (POTASSIUM HYDROXIDE)
BASES MOSTLY HAVE OH AS THEIR FORMULA
Answer:
10.04 g of NaOH is required for neutralization
Explanation:
neutralization reaction:
Molar mass of NaOH = 40 g/mol
Molar mass of HCl = 36.5 g/mol
So, 9.16 g of HCl = moles of HCl = 0.251 moles of HCl
According to neutralization reaction, 1 mol of NaOH is required to neutralize 1 mol of HCl
So, 0.251 moles of NaOH are required to neutralize 0.251 moles of HCl
So mass of NaOH required for neutralization = () g = 10.04 g
