Always use units. CM^3 or ML. ]]> 2018-11-21 13:02:40 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/306719718 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/306720963 Always be precise and go to the tenths place. The smaller graduated cylinder measures by .2 for each line and the big graduated cylinder measures by 1 for each line. You just have to be very careful and precise.  ]]> 2018-11-21 13:07:28 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/306720963 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/306722729 You have to take the mass and divide it by the volume you got. It is d=m/v. The unit is grams per CM^3. Same for liquids. You take the mass and divide it by the volume. ]]> 2018-11-21 13:13:36 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/306722729 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/308887720 you need mass of graduated cylinder. You also need mass of graduated cylinder and the liquid. Then you would subtracted them and then you would have the mass of the liquid. Then you need to find the volume and last dived mass by the volume.]]> 2018-11-28 16:37:24 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/308887720 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/308891087 It is the opposite of the liquid density you need the volume of the water volume of the water and the object. Then you subtract and get the volume of the object. Then you need the mass of the object. Then you will dived the mass and the volume of the object to get the density ]]> 2018-11-28 16:41:52 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/308891087 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/311577802 2018-12-05 20:07:30 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/311577802 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/311584310 2018-12-05 20:20:50 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/311584310 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/311587226 2018-12-05 20:26:54 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/311587226 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/314226282 it will dissolve  faster if you heat, stir crush the solute. soulte is the substance that can dissolve. solvent is the water of alcohol what ever it dissolved in. Aqueous is seeing if it dissolves in water and tincture is if it dissolves in alcohol solubility is when it has dissolved the maximum amount of solute. you can test this by stirring it for a couple minutes and once that is do you will poor out the water without getting the excess solute in the evaporating dish. Then you would boil off the water and then weigh the the solute that dissolve and you would subtract it from the empty watch glass and the cup to get the mass of it. ]]> 2018-12-13 13:21:07 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/314226282 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/314829211 the steps to identifying plastics

If it starts to bubble to high take the bunsen burner off for a minute.  don't let the liquid get above 105 in temp. make sure you have at least 5 ML. make sure that the plateau is within one degree and it has to do it 3 to 5 times. Do not let the distillation tube touch the bottom of the test tube or the water. Use striker to hold tube and hose in water so it does not fall out. Full up the water in the beaker to about 550ML.  ]]> 2018-12-18 15:21:13 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/315554022 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316389438 2018-12-21 13:27:17 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316389438 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316390036 2018-12-21 13:30:39 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316390036 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316849804 when you separate a liquid from a solid and save them so you can test them. having a pure liquid with a solid left over.  it is to help you collect a pure liquid so you can test it. ]]> 2018-12-29 18:50:28 UTC https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316849804 zzhamme https://padlet.com/zzhamme/hcl8y2cwfshs/wish/316850140 A test that you can do to identify .
