Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent Bond
Between 0.4 and 1.7 then it is Polar Covalent Bond
Greater than 1.7 then it is Ionic
For N and Se,
E.N of Nitrogen = 3.04
E.N of Selenium = 2.55
________
E.N Difference
0.49 (Weakly Polar Covalent)
As you have not provided remaining pairs, so if you have any of them, follow the method as mentioned above.
Answer:
Explanation:
Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate and bases donate in water which combine to form water molecules.
The chemical reaction between calcium carbonate and hydrochloric acid forms calcium chloride , water and carbon dioxide.
The balanced chemical equation is:
It is 1/100 of its original base.
I hope I helped! :)
Answer:
2RbNO₃ + BeF₂ → Be(NO₃)₂ + 2RbF, because Be keeps a 2+ charge throughout the reaction.
Explanation:
- It is a double replacement reaction.
- A double replacement reaction is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
- In this reaction, there is no change in the oxidation state of different atoms.
- It is just a replacement reaction.
<em>2RbNO₃ + BeF₂ → Be(NO₃)₂ + 2RbF, because Be keeps a 2+ charge throughout the reaction.</em>
