BACE EXAM 4.0 LABORATORY SKILLS 100% CORRECT the process of cleaning something, especially with a chemical, in order to destroy bacteria. Disinfection Decontamination is the removal of dangerous substances, radioactivity or germs from...? an area object or person Decontamination is the removal of what? dangerous substances radioactivity and germs What is the purpose of aseptic technique? Aseptic technique assures that you don't introduce contaminants into a specimen and that infectious agen...

temperature is related to KE how? temp is the average kinetic energy thermal energy is related to KE how? thermal energy is the total KE Brainpower enthalpy of fusion is ALWAYS greater than enthalpy of vaporization because? it has to break more bonds (solid --> liquid) the amount of heat depends on (2 factors) 1. the type of substance 2. the amount of the substance during a phase change does temperature change? NO if an archaebacerial species lives in a pool that is 0.01 M HCL wh...

BIOCHEMISTRY LAB 8 REPORT| PORTAGE LEARNING|WITH PROCEDURES, EXPLANATION AND FINAL RESULTS| LATEST UPDATE 2024 SCORED Lab 8: Isolation of Limonene CHEM 212: Organic Chem Laboratory Background: Distillation is a common wet-chemical technique used to separate and purify organic liquids. In this experiment, steam distillation was used to separate limonene (oil of orange) from orange peels. Steam distillation is a method whereby codistillation with water allows the distillation of relativel...

What is the role of albuminuria testing - Detect small urinary concentrations of albumin before there is irreparable renal damage Which of the following markers is often elevated with a solid tumor mass? - LDH. It is shown to be high with solid tumors. This makes it useful in monitoring the size of tumors during treatment. Which of the following accounts for 90 percent of osmolality in plasma? - Sodium (Na+). Sodium (Na+) is necessary for electrolyte balance. It associated with anions, whi...

how much BSA is needed to prepare 50 mL of 5 mg/ml of BSA (w/v)? - Answer-(50 mL)(5 mg,mL) = 250 mg a technician is assigned the task of inserting a gene, LanA, into a plasmid to ultimately be expressed as a therapeutic protein in E coli. label the following steps (1-4) in the correct order the technician must perform them to accomplish her task. - Answer-1) design primers to amplify the lanA sequence using polymerase chain reaction (PCR) and perform the PCR reaction 2) digest and provide ...

Recapitalization a technique used to purify organic solid compounds with the goal to dissolve and subsequently crystallize a pure substance from the solution. What are the four characteristics of a good solvent? -Target must be soluble in high temp with impurities soluble at room temp or at high temps -Must be chemically inert (non-reactive) -Low boiling point, or highly volatile What are the 5 basic steps to Recrystallization -Choose suitable solvent -Dissolve the impure mixture in the...

Objective: To examine the use of a phase transfer catalyst to effect an SN2 reaction in dichloromethane solution. The reaction will be conducted without extraction for product isolation. List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. - The reaction is performed on a small scale by mixing the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial. Sodium hydoxide (base) is added to ini...
