make sure to use water to stick the paper to the sides of the funnel. also be sure to fold up the filter paper.

the acid test is looking for one reaction and that is bubbles.if anything other then bubbles occurs then it is a no.

when doing metals, the first thing to do is the density. doing the density will narrow down your results. the next test is the magnetism test. the last test to do is the acid reaction test. do the density a second time with a different amount if their are still a few options for what metal it could be.

if after doing the micro melting point you still have the powder in the capillary tube, then do melting point. to do melting point you must put the powder in the evaporating dish. the 3 observations are melting decomposition or black

follow the flow chart on the plastics packet. once you find which number plastic it is, stop

# data[].attributes.body
plastics and metals are the first things that should be identified. they are easily picked out and have concrete tests run for them

the evaporating dish is used to separate a dissolved solid from a liquid. heat in the dish until all of the  liquid is gone and you are left with just the powder. CAUTION THE DISH IS HOT

this is used to separate two liquids. first you need to heat up the solution until you reach the first plateau. begin to collect the bioling solution in the condensing tube. this is pure because it is during a plateau. when the tempeature begins to rise again switch out the test tubes and collect the solution in a trash test tube. keep repeating until you are sure that you have collected enough liquid.

in the sludge many substances will be mixed together and it is our job to get the separated

the only tempeature that is needed to be written down is the temp that the powder melts at. in order to tell that it is melted the powder will become clear and the level will rise a bit.

to find boiling point. you must use the handheld and dont let the wire fall in the flame. when the water starts to bubble it is now boiling. after the first sign of boiling, take 6 more reading

# data[].attributes.body
the volume of the liquid is at the bottom of the meniscus. to find the mass you need to find the mass of the empty graduated cylinder and the find it with the liquid and subtract

# data[].attributes.body
to find density you need to find the mass and volume of the substance

# data[].attributes.body
intrisic properties are properties that can identify the substance. IT DOESNT MATTER HOW MUCH YOU USE.

sludge is a mixture of liquids,solids and various chemicals. the objective of sludge is to find the hazardous chemicals mixed in the sludge
