1. Why the can that did not scratch did not produce bubble as the one the got scratch.
2. is the base have affect on the cans as the acids.
3. Why the chemical did not react with the plastic inside the can.
4.How the bottom part of the can have more reaction than the middle part of the can.
5. Is the acid and base react with aluminium.

a) NH3 (g) + HCl (g) → NH4Cl (s)

b) Independent: Amount of amonia solution (concentration)
Dependent: The amount of product
c)If we add more ammonia into the reactant then the product will be increased.

a. For the first two trials we use the same size of the cup and this made the volume of the two big cup are close to each other, but there are still one that has the higher volume this might be caused by the speed of the person who carrying the cup.
b. For the second trial we use a different size of cup one are bigger and one is smaller. The result is that the one who has a bigger cup can transfer the water more cased it to fill the cup to make it have higher volume. However, as the time goes by the water level is low cased the big cup can carry the water the same size as the small cup.
c. For the third trail both water and cup are in different which gave the one who have bigger cup put more water at the end of the experiment.
d. The Dynamic Equilibrium can mean that when the two substance cannot further extent to the next level they both just reach the maximum point.

The energy stored in the covalent bond.
To make the graph more accurate we can use temperature to measure and using q=mc(deltaT) to find the energy in each temperature state so we can know the specific point on the graph.

a. So, after we combine the sulfuric acid with the sucrose it made the sucrose turn into black color ,which can be called the caramel and as you add more sucrose into the beaker more. The steam start to form which might caused by the change in state of liquid into gas. In the mean time, the foam also forming up in a black color.
b. C12H22O11 + H2SO4 = 12C+11H2O+H2SO4
c. During the end of the reaction how does the steam is forming up?/ How does the sugar changes from the solid state into a more like a liquid state? / Why does the color is getting darker and darker? / Is this reaction a exothermic or endothermic reaction? / Where does the heat in the reaction come from?

Write a question -
1. If we increased the concentration, but decrease the temperature is the reaction rate will be fast or slow?
2. Between temperature and concentration which one are the variable that affects the chemical rate the most?
3. Is the number of different substances affecting the reaction rate.

# data[].attributes.body
a) They are many factors that can make the reaction occur faster like the temperature, pressure, concentration, catalyst, and surface area can all be the reason that makes the reaction occur faster. Moreover, all of the variables make the molecule to have more energy so that it is easier for them to collide with another molecule.
b) The spontaneous process is when the reaction occurred without involving adding more external energy. Furthermore, the spontaneous process can relate to the chemical reaction in the ways that during the reaction they are no extra energy was added according to the law of conservation of energy.

# data[].attributes.body
a) chemical reaction - 2H2O2 = 2H2O + O2
b) Type of reaction - Decomposition reaction
c) Describe the reaction - Before the reaction of the two chemicals they are both in a liquid form, but after they are mixed together it changes the state a more a forming or solid form this might happen because of the yeast. Moreover, after the reaction, it also forms a gas which might be oxygen.
D) List variables - The yeast and the soap

After listen to my friend teach during the class is that i know how to convert gram to mole and i also understand the stoichiometry more. However, the question that i still confuse is write a unbalance equation into balance equation with perfect arrangement.

Reactants vs Products
The similarity of the product and the reactant is that the number of atoms of each element is the same because it is related to the law of conservation of energy. Furthermore, the differences between the product and the reactant are that the product has a new substance this is caused by the rearrangement of the equation by chemical reaction. Moreover, the amount of energy and mass are also different for the product and the reactant.

A) Observations from the demonstration:
- When the Sodium bicarbonate combine with the calcium chloride nothing is happening because they both a Ionic compound, but after the water was added it started to have the reaction this is because the water will separate the charge from each other. Moreover, during the reaction happen the bubble was formed and cause the gas to fill the bag. As a result, the temperature was dropped from 26 to 22 degree Celsius and also the weight from 68.9 to 66.75 gram. However, we combine the water with some of the Phenomenological which is the chemical indicator,but when it react with the chemical the color is not changing.
B) Phenomenon - picture above
C) Chemical reaction:
- NaHCO3+CaCl2+H2O --> CaCO3+CO2+NaCl+HCl

phenomenon question
1. How did the temperature affect the pressure inside the flask?
2. Which gas law is related to this experiment?
3. Why do we need to add a straw on top of the flask?
4. After, the flask is flipped down into the pot and made the water come out this is caused by the gravitational or the difference of pressure.
5. If we heat the flask water in a shorter time, does the amount of water move into the flask the same as in the experiment or not.
6. Does the pressure inside the flask the same as the outside pot.
7. Why did the temperature change at the end of the experiment.
8. If we add more water into the flask will the resulting change
9. Does the temperature affect how fast it sucks up the water.
10. If we not shake the flask is the result will be the same.
