Amylopectin The absorbance value(x) read from cuvette containing starch and water represents the total amount of starch-iodine complex. The absorbance value(y) read from cuvette containing starch‚ water and α-amylase at the respective temperature or pH represents the amount of starch-iodine complex which is left after the enzyme has hydrolyzed the starch.In order to get the amount of product;P (maltose and glucose) formed‚ need to subtract the (y) value from the (x) value.

PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. A quick summary of the trends The oxides The oxides we’ll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O | Those oxides in the top

Intravenous therapy or IV therapy is when a patient is given liquid substances directly into a vein. The word intravenous means "within a vein”. Therapies administered intravenously are often called specialty pharmaceuticals. IV therapy is commonly referred to as a drip because many of the ways it is administered use a drip chamber‚ which prevents air entering the blood stream and allows an idea of how much is flowing in to your body. Compared with other ways of administration the intravenous route

Purpose: The purpose of the lab was to investigate and demonstrate hydrogen bonding and London dispersion bonding in water and rubbing alcohol. Hypothesis: I believe water will have the greater surface tension because rubbing alcohol’s density is lower than water’s. Materials: * Water * Isopropyl alcohol (rubbing alcohol) * Pennies * Paper clips * Flasks * Cups or jars * Wax paper * Eyedropper Procedures: Part 1: Surface tension and vortex: * Fill

5.1. Processing Steps of Hydrogen Production from LPG Conventional process for producing hydrogen from light hydrocarbons involves the following process steps: • Feed preparation • Sulfur removal • Steam reforming • CO shift conversion • Autothermal reforming • Process gas cooling • Synthesis gas purification (PSA pressure swing absorption) [5] 2.5.1.1. Sulfur Removal LPG feed first passes through an ambient temperature sulfur adsorption vessel

Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Finding the formula of magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Eye protection must be worn Apparatus Crucible and lid
