PE & Graphs - Where is energy stored in a molecule?  What can you change about your graph to make it more accurate.
- The energy might be store in the electron during the covalent bond.
- To make it more accurate, according to the formula Q=cm/\T. We might use the specific point of temperature to cause it more accurate.

Phenomenon - Complete the following tasks regarding the demonstration reaction of Sucrose dehydration.
(a) list your observations from the demo ran
-  When the liquid was added into the amount of sugar, the color change to yellow and start to burned up after we add more sugar.
(b) write the balanced chemical reaction
- C12H22O11 --> C12 + 11(H2O)
(c) write a minimum of 5 questions about reaction
- What kind of catalyst can be use to increase the rate in this reaction?
- What was the amount of sugar in this experiment?
- Does the amount of sugar affect the reaction rate?
- Can the chemical liquids that is put into the reaction can be change into other types?
- If we are changing the temperature in this experiment, what thing are we changing its temperature?

# data[].attributes.body
- Will the amount of catalyst affect the reaction rate/ the speed of the reaction?
- If the change the temperature of the water or any element, will the elephant toothpaste reaction react faster or slower?

# data[].attributes.body
(a) Write a 2-3 sentence summary to explain why some reactions occur faster than others.
- The more of molecule collide with each, the fast reaction will be. More chance of molecule collide, the more chance of reaction speed up.
(b) Define "spontaneous" and state its relationship to chemical reactions.

- It is a process which occurs without input of any electrical energy into the system. Spontaneous release free energy that can be use for work.

a) 2H2O2 -> 2H2O + O2
b) decomposition reaction
c) when the potassium iodine was pure into the liquid in another beaker then it form foam. The foam was fast pop up and fill around the house.
d) the amount of potassium iodine may affect how fast the reaction is.

(a) The sodium bicarbonate combine with the calcium chloride, nothing happen (ionic compound). Then after the water is added, the reaction was happened because water separate the charge and the bubble was formed then filled the bag with gas. The result of experiment, temperature dropped from to 26 -->22 degree and the mass decrease form 68.9 --> 66.8 gram.
(b) picture
(c) -NaHCO3 + CaCl2 + H2O --> CaCO3 + CO2 + NaCl + HCl

Similar - The product and reactant has the same chemical  substance or amount or atoms..
Different - After the chemical substances are mixed together, it cause foaming.

1. Why does water in the beaker boil that fast?

2. What does gas reach with?

3. Why does the beaker temperature cool down so fast?

4. What is the difference between 2 water in different beakers?

5. How does water in a red beaker affect the temperature of other beakers?

6. Does the water volume affect the reaction?

7. How does the red water/liquid react like that?

8. Does the temperature affect how fast it sucks up?

9. What energy causes the motion to go upward?

10. How does the reaction happen without any substance?
