1. Why does each one has different reaction?
2. What chemical can be used to make them all had same reaction?
3. Why does coke and A&W have different reaction, although they were both soft drink?
4. If adding more NaOH or Hal will make the reaction greater?
5. Are there any variable that can be added to make the reaction stronger?

a. NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH−  (aq)
b. Changing of color
c. If more concentration of NH4CL was added, then the pink color turn completely clear.

a. The volume of the first 2 trial have almost same volume for both two cups, therefore when scooping the water up each time it will has mostly the same volume and mass.
b. The second trial with 2 different size of cup, this has the huge different as the big cup has greater volume and the small one would have less volume. However, the time flew, the volume of water that each cup scoop up will be equal due to the level of water.
c. The third one with 2 different size of cup and different volume of water in the bin. In this case, the water in the bin that scoop up by the big one has more water, as opposed to the one with small cup. In this case, we were looking for what time did they took to had the equilibrium.
d. In my opinion, it is a point that both two things can hold the liquid or something in the same volume, even they were having a huge difference between the size.

The energy that stored in the molecule is in the bond. I think to make the graph becomes more accurate, I need to add numbers about the detail of the reactant and products. To make it more obvious and easy to understand.

A. When adding the sulfuric acid to the sucrose, the reaction gently happens. It turns color from yellow to black. At first the product looks chunky and not that liquid and not solid but after stirring it the product become liquid. Next there is a stream happening and also it increase in size the product become bigger and there is also some giggles sound and bubble. Lastly, the product turns into the hard solid and has the temperature at  64 degrees celsius.
B. Sucrose-C12H22O11-> C+H2O
H2SO4+C12H22O11-> C+H2O+SO4
C.
- Why it is change from solid to liquid?
- Why does it become hotter?
- Why does it change color?
- How do the sugar can become a carbon?
- What do we need to add if we want it to has bigger reaction?

When adding more reactant the reaction will be greater in size or longer in time?

a. Every reaction takes different time to make a reaction, some is slow and some is very fast. To make the reaction happened faster we can use more reactant (amount of reactant) or we can also use a catalyst which is the substances that help the reaction to occur much faster.
b. Spontaneous is the reaction that occur without any additional eternal energy. Both spontaneous and chemical reaction make out similar product(fire) but chemical reaction needs some additional reactants or energy while spontaneous needs nothing.

a. 2 H2O2 (aq) --KI+NaI+C19H14O2(Catalyst)--> 2 H2O (l) + O2 (g)
b. Decomposition
c. When combined the reactants together it makes out the product as a foam. This happened because the decomposition of hydrogen peroxide by sodium iodide, potassium iodide and yeast or a catalyst.
d. NaI, KI, and Yeast

CaCl₂+ 2NaHCO₃ ->  CaCO₃ + 2NaCl + H₂O + O2

The similarities: Both product and reactant still have the same amount of atom such as Cl and Na still has 2 and Ca still has one.
The differences: The product has been form a new element, H₂O and O₂. By this differences, it has a new gases shown out.

Baking soda- 10g
CaCl- 19.7g
Water+ Phenolphthalein- 20g
Before the reaction: 68.9g and 26°C
After the reaction: 66/7g and 22°C
The observation:
1. All ingredients are mixing and bubbling.
2. The plastic bag fills up with the air.
3. When the liquid and solid mixed, the chemical become a little bit pink.
Chemical reaction:
CaCl2+ 2NaHCO₃ =  CaCO₃ + 2 NaCl + H2O + O2
The reaction happens because the mixing of baking sodium and Calcium Chlorine.
