Apron, goggles, and gloves all for protection in the lab.

Answer from: briashia

I will start of by naming what's RIGHT and WHY.

Aprons, goggles, and gloves are proper laboratory clothing.

The apron is correct because it covers your clothes and does not allow harmful chemicals to get on them.

Goggles are correct because it covers your eyes. It helps to keep unwanted harmful chemicals to come in contact and hurt your eyes.

Gloves are correct because you may protect your hands from getting burned and keeping them safe.

I will now name what's WRONG and WHY.

Oversized sweatshirts, sandals, contact lenses, and jewelry.

Oversized sweaters are wrong because baggy clothes and labs do not go well together. It can get stuck on or in things, it can spills items, easily burn when near fire, etc.

Sandals are wrong because your feet are not protected. If something like acid get knocked over (you wont be using/exposed to acid, it's an example) it can harm you feet badly. The same thing goes with unknown substances. The point of a lab is to have fun yet be safe, not to injure yourself.

Contact lenses are wrong because it's not a form of eye protection. Now, I'm not saying that you shouldn't where them if you/somebody could have trouble seeing, just put goggles on too. Like I said, you should not be injuring yourself.

Lastly, jewelry. That wrong because of a similar reason of oversized sweaters. It can get stuck/yanked on something. That would create a mess and the lab would not be safe to work in.

Hope this helps!!

Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is a colourless liquid organic compound with the chemical formula ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called glacial acetic acid. vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. it is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7 3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366 chemblchembl539 chemspider171 drugbankdb03166 echa infocard100.000.528ec number200-580-7e numbere260 (preservatives)gmelin reference1380iuphar/bps1058keggd00010 meshacetic+acidpubchem cid176rtecs numberaf1225000uniiq40q9n063p un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4) key: qtbsbxvteameqo-uhfffaoysa-n smilescc(o)=o

Space-time metric ds2= -dt2+at2dx2+bt2dy2+ct2dz2 (a)how does the area of a rectangle with vertices at ( x=0, y=0, z=0 ), (1,0,0 ), ( 0,1,0 ) and (1,1,0 ) changes with time? (b) if a photon moving in the x direction starts from the origin at t=1, when does it reach x=l? (ds=0 for the trajectory of a photon.) (c) the proper time for a particle is defined by cd=ds. what is the proper time for a particle to move along the trajectory ( x(t)=t, y(t)=0, z(t)=0 ) from t=0 to 1 ? what is the condition on the parameter a so that the velocity of the particle never exceeds the speed of light ?

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.
