ABSTRACT The study was conducted to determine if the limonene contained in orange oil is a possible alternative source of energy to produce heat. It is concluded that duration of flame is significantly influenced by the amount or volume of limonene content. The limonene was effective enough as a fire starter. The flame produced had a consistent intensity. Its lengthy duration implied that it has the potential to be an alternative source of energy. INTRODUCTION Background of the Study Orange

be extremely toxic for aquatic organisms‚ so finding it in soil can be alarming‚ especially if it is in large quantities. I have found that unknown sample B iron(iii) sulphate. I have identified it to be iron as it gave a yellow colour during the flame test narrowing it down to be barium or iron(iii). It then produced a yellow precipitate during sodium hydroxide test showing that it was iron(iii) instead of barium. The chemical equation for this reaction is: Fe2(SO4)3(aq) + NaOH(aq) Fe(OH)3(s)

I have to tell the Jews what I saw even though they don’t believe me. Talk. Talk. Talk. “Look at the fire! Look at the flames! Flames everywhere!” It hurts. It’s warm. What is it? My head‚ it’s bleeding. But I can’t feel anything. Why don’t they believe me? Why? Are we heading toward the flames? Are my husband

Lab #4 Emission Spectroscopy and Flame Test Date of Lab: 10/24/13 OBJECTIVE To observe a continuous spectrum‚ emission spectrum‚ and an absorption spectrum‚ and be able to distinguish among the three. To be able to identify metal ions by doing a flame test and looking at a spectrum. At the same time increasing the ability to use and understanding of lab equipment‚ in this case‚ a spectroscope. To be able to calculate the frequency and energy of certain frequencies of light. PROCEDURE

The study focuses on extracting ethanol from Santol peelings‚ using white and brown sugar‚ and comparing it to the commercial in flame propagation‚ duration‚ temperature difference‚ and heat content with varying concentrations. The study is an experiment divided into three phases‚ fermentation‚ distillation‚ and the flame testing. Gathered data has been tabulated and treated with Z test and Randomized Block Design. With the findings‚ Santol peelings can be a potential source

absorption spectroscopy is based on the same principle as the flame test used in qualitative analysis. When an alkali metal salt or a calcium‚ strontium or barium salt is heated strongly in the Bunsen flame‚ a characteristic flame colour is observed: Na -- yellow Li-- crimson Ca-- brick red Sr-- crimson Ba --green In the flame‚ the ions are reduced to gaseous metal atoms. Compound -------- heat------- atoms The high temperature of the flame excites a valence electron to a higher-energy orbital. The

Tongues of the flames seemed to lick the ceiling of the second storey. I rang the fire brigade. Soon the fire brigade was heard rushing to the place. The fire brigade people‚ wearing fire proof uniforms and steel helmets on their heads‚ started playing the hoses on the flames and also on the adjoining houses

Flames have been inextricably linked with humanity since the origins of the first civilizations; immortalized in myth‚ commended by culture‚ and worshipped in religion. The epitome of heat and warmth‚ of energy‚ power and action‚ fire’s virtues undoubtedly support the importance it is associated with. Flames keep back the encroaching darkness‚ the perennial cold. It is the internal flame that sparks the innovation and creativity within the human mind and the external fire that has allowed for humans
