First you have a knowledge of bond order which is
B.O=(no. of electrons in bonding orbital - no. of electrons in non-bonding orbital)÷2
Note:
bond strength is directly proportional to bond order.
For oxygen:
B.O=(6-2)/2= 2; after the removal of two electrons(removal occur from non-bonding orbital)
B.O=(6-0)/2= 3 (As B.O increased bond strength increased)
For Nitrogen:
B.O=(6-0)/2= 3; after the removal of two electrons(removal occur from bonding orbital)
B.O=(4-0)/2= 2 (As B.O decreased bond strength decreased)
3*40+3*2*35.5=333* Avogadro’s number =
1.98*10^25
Answer:
A
Explanation:
Electrons are significantly smaller than neutrons and protons.
Electrons have a diameter of less than 10^-16 centimeters, whereas protons and neutrons have a radius of about 10^-13 centimeters.
Answer:
The answer to your question is below
Explanation:
Data
Test tube 1 Test tube 2
Magnesium + Sulfuric acid Magnesium + Acetic acid
Mg + H₂SO₄ Mg + CH₃COOH
a) Test tube 1 will have a more vigorous reaction than test tube 2.
b) Sulfuric acid is a strong acid and Acetic acid is a weak acid.
c)
i.- Sulfuric acid because is a strong acid
ii.- Acetic acid because is a weak acid.
