Chemistry - correct answer Study of matter -composition -structure -energy changes it goes through Matter - correct answer -is all around us -can be identified by its physical or chemical properties -any substance regs takes up space (volume) and has mass Atom - correct answer Most simple form of matter Element - correct answer -homogenous -cannot be broken down simpler by physical or chemical means -atomic numbers -periodic tables -represented by one or two letters Compound...

CHEM 2100L/2211L Lab Final | with a complete study set Experiment #1 Re-crystallization - What is the specialized melting point technique that is used to determine the identity of an unknown compound? - Comparative Melting Point -- this is when you make a 50:50 mixture of the unknown compound and the substance you think it is based off given melting point values What are the five steps of re-crystallization? - 1. Choose an appropriate solvent 2. Dissolve the impure mixture in the s...

Non-calibrated glassware that is used to approximate measurements (not used for actual measurements) - Correct Answer -Test tubes, beakers, erlenmeyer flasks, round-bottomed flasks, transfer pipets, petri dishes, watch glasses, bottles, jars, and vials Test tubes - Correct Answer -small and allow a large number of samples to be arranged in a stack for easy processing Beakers - Correct Answer -wide-mouthed cylinders with a lip to allow pouring Erlenmeyer flask - Correct Answer -t...

Unit 4B: Making Nail Vanish Remover Introduction In the manufacture of ethyl ethanoate, there are a few techniques used, one of them being reflux. The principle behind using reflux is that it boils the reactants without losing any product or reactant, especially through vapour or gas. In the reaction there is a round bottom flask containing the reactants and a condenser with a water inlet and output. Due to organic chemicals being inherently unstable, when heated they will evaporate, res...

experiment 1 - answer-basic lab techniques identification of substances by physical properties experiment 2 - answer-chromatography experiment 3 - answer-analysis of hydrated of hydrated salt experiment 4 - answer-heat of neutralization sig figs - answer--non zero digits are significant -any zeros between digits are significant -zeros to the left of the first non zero digit are not significant -if a number ends in zeros to the right of the decimal point, those zeros are significa...

Observational recordings - Answer - should not be altered, erased, or whited-out to make corrections - drawing a single line through it Parts of a lab report - Answer 1. title 2. abstract - contain the hypothesis - include a control and one variable 3. introduction 4. methods 5. results 6. conclusion / summation Volumetric flask - Answer - used to accurately prepare a specific volume and concentration of solution Erlenmeyer flasks - Answer used for mixing, transporting, ...

Experiment 7: We examined 3 different types of polymerization 1. Condensation (interfacial polymerization) 2. Chain Addition 3. Cross-linked what did each accomplish? - Answer 1. Nylon-10,6 is made from sebacoyl chloride and hexamethylene diamine 2. Polystyrene is made from chain additon of styrene and the initiator as benzoyl peroxide which generates radicals with heat, these radicals react with the styrene to begin chain addition Experiment 7: Chain addition vs Condensation Polymerizat...
