Niels Bohr’s model of the hydrogen atom‚ was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns‚ scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form‚ and then leaving the gas in the form of light. He figured the light rays to be quantized‚ meaning only certain frequencies of

but because it can cause hazard for the humans and possibly to the environment‚ the hydrogen peroxide is now as an alternative to replace formalin for a common treatment for parasites (Pedersen and Flemming‚ 2010). Graslund et al‚ 1 (2003) showed that the hydrogen peroxide acts as chemical that served several purposes such as to eliminate bacteria‚ parasite and also algae in shrimp farming. However‚ the hydrogen peroxide still can be hazardous for the health of farmers (Boyd‚ 1999) and also affect
