Also to identify what each items are by doing tests. ]]> 2019-10-25 15:32:46 UTC https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/402623845 Acid Test -day 1 sabrinagao3 https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/403395158 -works for metals and nonmetals
-take some acid and squeeze it on metal 
-if bubbling means yes bubbling
-do a pinch if its nonmetal acid test
-if change colors than not reactions ONLY CAN BE BUBBLES
-soon wash off substance than things are fine]]> 2019-10-28 15:36:32 UTC https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/403395158 Word sabrinagao3 https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/403400363 2019-10-28 15:43:25 UTC https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/403400363 What is Solubility? sabrinagao3 https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/407695078 the greatest amount of solute that can dissolve in 100ml of water.]]> 2019-11-06 19:29:06 UTC https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/407695078 Water -aqueous sabrinagao3 https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/407695417 2019-11-06 19:29:32 UTC https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/407695417 Alcohol -tincture sabrinagao3 https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/407695454 2019-11-06 19:29:35 UTC https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/407695454 how to find density? -metals day 1 sabrinagao3 https://padlet.com/sabrinagao3/f9i5f3inuq1f/wish/410692134 solid (regular)

solid (irregular) 
do water displacement
1. add water to the graduated cylinder (about halfway if no sure) and record volume. 
2. tilt and slide the object into the graduated cylinder so that no water splashes out (this could change your starting volume of water) and record your new volume. 
3. Subtract the two volumes. This is the volume of your object

2.       Record the mass
3.       After recording, add liquid into graduated cylinder
4.       Figure out mass and record mass
5.       Subtract the two mass
6.       Volume = amount put in graduated cylinder 
7.       D= M/V
