Why does all the water got suck into the flash?

Does it have anything to do with pressure?

If there is no rubber stopper can the flask still suck the water in?

The water doesn’t fill in the whole flask. Is it becasue there is no more room for more water? (Pressure already fill all the flask)

If there is only pressure and no heat in the flask will it affect the result?

Why is there a little bubble in the flask?

How does the temperature just change rapidly from hot flask to room temperature?

Does the container shape affect the result of the experiment?

If there is only pressure in the flask and no water will the result be the same?

Does this experiment work with another type of liquid? (not water)

1: Put in 10 grams of Sodium (19.7)

2: pour that into a bag.

3: Add 20 grams of calcium choline.

4: Pour it into the bag.

5: 26 degrees celsius ( doesn't react until add water)

6: Add chemical indicator into the bag (when it is acidic it will turn pink) 20 ml Phenolphthalein.

7: Don’t spill the chemical, squeeze the air out of the bag.

8: Measure the whole thing on the scale.

9: 68.97gram.
10: Mix the chemical

Observation:

1: Bag must have less air as possible

2: Bubbles are formed after reaction

3: 66.7 gram lower mass.

4: 22 degrees celsius (result) lower temp

B. The type of reaction that has been occurred in this experiment is the decomposition reaction
C. The reaction in this experiment cause a big foam to explode out of the bucket. This happens because sodium iodine reacts with hydrogen peroxide, which split oxygen from sodium. But because of the soap causes the intensity and traps the oxygen inside. End up with result that there is exploding foam.
D. The Potasuim Idodine helps the yeast to make the reaction happen faster and also maximizes the size of elephant toothpaste that will be created.]]> 2022-02-07 01:18:26 UTC https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2032034235 3) Checklist 2.3 Question vijaks2023 https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2046068270 1. From the simulation, there is not a lot of difference in a reaction that has been shown between catalyst and temperature. Do these two make the particle react in the same or different way?
2.Which way perform the best to speed up the reaction?
3. What way can be use to slow down the reaction and perform the best?]]> 2022-02-14 12:22:07 UTC https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2046068270 Unit 2.2 notes CHECKLIST vijaks2023 https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2097588179 A. After they combine the two elements together. The water starts to change color to black. Then more sucrose has been added. Which affects the black liquid and changes some of it into gasses. The black foam form and grow out of the bottle. B. b. C12H22O11 + H2SO4 = 11H2O+H2SO4+12C C. 1) What happens that causes the steam in the reaction? 2) Why does add more the second time cause the foam but the first time that they add sulfuric acid, nothing happens ? (accept the color change) 3) What type of bond or chemical reaction is this? 4) Is there any instant temperature change during the reaction. 5) is this endo or exothermal reaction.?]]> 2022-03-16 08:32:00 UTC https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2097588179 Unit 2.2 notes CHECKLIST vijaks2023 https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2097601995 To make the graph become more accurate. We would need to included somekind of measurement that can tell us the Potential energy in reactant and product. Also including the number of loss potential energy after the reaction.]]> 2022-03-16 08:41:15 UTC https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2097601995 vijaks2023 https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2112960860 The phenomenon that we have experienced is the equilibrium of the water in a container. The first two trails are similar in the amount of water because the cup that the two students use is the same size. So it depends on the student's technique and skill to empty water than the other student. But no matter how hard they tried the amount of water at the end will be equal because the cup is the same size. This means that the container will be at an equilibrium amount since the starting point of the test. The third trial is stating with an equal amount of water but different cups of size. However no matter how hard the bigger cup trying empty their container. It will never be empty-lit because as the water keeps decreasing the amount of water that the bigger cup can take out is also lower. This keeps happening to the point that the cup can only take in the same amount as the small cup. At this point, the situation becomes like the first two trails where it hit equilibrium and both equally will go in the loop of running back and forth to take in the water, but it will never end. One container will have more water but it will never go over that. The last trails is one student start with larger amount of water]]> 2022-03-25 01:45:41 UTC https://padlet.com/vijaks2023/eq4xm1xmokhvg487/wish/2112960860
