Background of the Study Ethanol is a clean-burning‚ high-octane fuel and is made from a renewable resource made from American corn and different cellulosic materials. Ethanol has many uses. It can be used as a biofuel (which reduces greenhouse effect) and it can be used for making different materials like perfumes and explosives. It is also called ethyl alcohol. Ethanol can be produced by banana peelings but we don’t know which peeling of different banana species can produce more ethanol. The peelings of

| Ethanol Fuel Production from Banana Waste Peelings | CHAPTER 1 INTRODUCTION Due to the modernization to our country‚ there were new things that are added in the basic necessities of an individual‚ one of this is fuel. Since fuel can be afford in a high price‚ some people afford fuel. To resolve this problem‚ we need to find abundant and renewable source of fuel that is low cost. The project entitled “ETHANOL FUEL from BANANA PEELINGS” can help to solve this problem. This project will

Rabang‚ Maika I. 2B-Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is a technique in separating two liquid components. There are two types of distillation used in this experiment known as the simple and fractional distillation. The objective of this experiment was to be able to determine the amount of Ethanol in the given

WASTE TREATMENT The treatment is dedicated to finding solutions to agricultural problems by developing alternatives that maintain levels of production while cultivating healthy foods‚ preserving the health of farmers‚ and not polluting surrounding ecosystems. The banana industry creates many by-products that result from the harvesting and processing of bananas. These by-products are banana peels‚ banana stems‚ and liquid wastes. Currently these wastes are dumped in landfills‚ rivers‚ oceans and

B1: The permeability of the cell increases enormously during the action potential. Comte Whitney Electricity is vital for neural function and communication. The semi-permeable membrane and presence of charged particles in solution (ions)‚ enables the cell to have control of an electric potential. The cell The concentrations of Na+ and K+ ions upon either side of a cell’s membrane are not equal. In order for the equilibrium to be restored‚ sodium will attempt to enter the cell‚ whilst potassium will

ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness
