I REALLY NEED HELP ASAP! PLEASE 1. How do the physical properties of the slime differ from the physical properties of the glue and borax alone?
2. Stretch the slime slowly. Can you make a sheet thin enough to see through?
3. Form the slime into a roll. What happens if you pull the ends of the roll quickly? What happens if you pull it slowly?
4. Put a clean beaker on a table upside down. Roll the slime into a ball and place it on top of the beaker. Describe what
has happened after 30 minutes.
5. Roll the slime into a ball. Does it bounce?
6. Do some research on polymers. Make a list of 20 items around the house that are composed of polymers. (Hint:
Read labels!)

1.Borate ions, provided by the borax (hydrous sodium borate), cause the vinyl molecules in the glue to form cross-linked bonds. The process of cross-linking continues to alter the physical properties of the polymer. As more and more bonds are formed, the characteristics of the polymer change.

2.

If we pull the ends of the roll quickly, it will break.

If we roll the slime into a ball and place it on top of the beaker it slowly flow down.

3.When you pull slowly, your slime will stretch. However if you pull quickly it will break. Slime will slowly flow making it seem like a liquid, but it can also bounce which makes it seem a bit like a solid.

4.If we roll the slime into a ball and place it on top of the beaker it slowly flow down. After 30 minutes, slime will settle and behave as a solid, because water evaporates.

5.Yes, the slime ball will be able to bounce.

6.High Density Polyethylene, HDPE : bottle caps, folding tables and chairs, food storage containers, plastic bags, water pipes for domestic water supply. MDPE : shrink film, carrier bags, screws and enclosures. Linear LDPE : toys, lids, buckets, containers, bubble wrap.

Explanation:

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
