<h3>
Answer:</h3>
4.227 × 10^-19 Joules
<h3>
Explanation:</h3>
Energy of a photon of light is calculated by the formula;
E = hf, where h is the plank's constant, 6.626 × 10^-34 J-s and f is the frequency.
But, f = c/λ
Where, c is the speed of light (2.998 × 10⁸ m/s), and λ is the wavelength.
Given the wavelength is 470 nm or 4.7 × 10^-7 m
Therefore;
E = hc/λ
= (6.626 × 10^-34 J-s × 2.998 × 10^8 m/s) ÷ 4.7 × 10^-7 m
= 4.227 × 10^-19 Joules
Therefore, the energy of a photon with 470 nm is 4.227 × 10^-19 Joules
Answer:
Chemical reactions takes place
Explanation:
Chemical energy stored in bonds of chemical compound are released when chemical reactions takes place.
Chemical energy is a form of potential energy that is found in chemical bonds.
- When chemical reactions occur, bonds are broken and formed again.
- The process of breaking and forming new bonds releases chemical energy.
- In this manner most chemical reactions are often accompanied by energy changes
- The energy changes is due to the formation of new bonds.
