Compare and contrast the properties of acids and bases. include two similarties and two differences.
gtnhenbr [62]
Hello!

Similarities:

-They can conduct electric current because they both are ionic substances.-

-They both form Water and Salt when neutralized. 

Differences:

-Acids release Hydronium ions (H₃O⁺) when hydrolyzed while Bases release Hydroxyl ions (OH⁻) when hydrolyzed. 

-Acids are commonly formed with non-metals (such as Chlorine, Sulfur, Oxygen, and Nitrogen) while Bases are commonly formed with metals (such as Sodium, Potassium, Calcium, and Copper). 

Have a nice day!

Answer:

λ = 4.59 ×10⁻³ nm

Explanation:

Given data:

Energy of light = 4.33 ×10⁻¹⁴ J

Wavelength of light = ?

h = 6.626×10⁻³⁴ js

c = 3×10⁸ m/s

Solution:

Formula:

E = hc/λ

4.33 ×10⁻¹⁴ J = 6.626×10⁻³⁴ Js×  3×10⁸ m/s / λ

λ =  6.626×10⁻³⁴ Js×  3×10⁸ m/s  / 4.33 ×10⁻¹⁴ J

λ =  19.878 ×10⁻²⁶ Jm  / 4.33 ×10⁻¹⁴ J

λ =  4.59 ×10⁻¹² m

λ = 4.59 ×10⁻³ nm
