this gene codes for a membrane protein that’s function is transportation of chloride ions between certain cells and the extracellular fluid. In mutation ∆F508‚ the proteins with deleted phenylalanine don’t insert into the membrane resulting in ion migration of chlorine being disrupted leading to the build-up of mucus. Chlorine’s negative charge disrupts the electrical potential of the cell causing certain molecules i.e. sodium to enter. The combination of NaCl is then excreted in vast amounts. This

constituent. Then from the weights of the sample or precipitate‚ a percentage can be calculated out of the constituent. Solubility is the amount of a substance which is called the solute‚ dissolves in a volume of liquid substance called the solvent. Sodium chloride can be dissolved in water therefore we can say it is soluble and sand is made up of tiny rock particles or silica which do not dissolve in water therefore insoluble. From the NaCl solubility curve it can be said a slight increase in temperature

ABSTRACT Cockroaches are the most noted pests insects due to their population. Cockroaches are also the hardiest insects on the planet because they have a capability to stay live for a month without food. The high price and health risks problem from food branded chemical insecticides gives dilemma to Filipino household. Respiratory diseases can also get from chemical insecticides inhaled by a person. This study seeks the possibility of using the extracts

Conductivity of Ionic and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water

the value of x in the formula. 2. For the data in problem number 1 above‚ what is the mass percent water in the hydrate? 3. Calculate the number of grams of water that could be obtained by heating 2.00 g of sodium sulfate decahydrate (Na2SO4.10 H2O). Hydrates Analysis Objective: The formula for an unknown hydrate is quantitatively determined by heating the unknown hydrate to constant mass and calculating the ratio of the moles of water to the moles

1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane. Experimentally the lab students will see the reaction take place using their knowledge from lecture class to justify
