Why the can that did not scratch did not produce bubbles like the one that got scratch.2. is the base have an effect 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. Are the acid and base react with aluminum.

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 trial 1 we use the same size of the cup and this made the volume of the two big cups are close to each other, but there is still one that has higher volume this might be caused by the speed of the person.
b). For trial 2 we use different sizes of cups one is bigger and one is smaller. the result is that the one that has a bigger cup can transfer more water than the smaller one, however, as time goes by the big cup cab carry the water the same as the small cup.
c). For trial 3 we have both water and cups are in different which gave the one who has bigger cup put more water at the end of experiment
d).a chemical equilibrium between a forward reaction and the reverse reaction where the rate of the reactions are equal.

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

1. When Mr. Dan put the sugar and the another chemical liquid in the substance start to turn black and the smoke is coming out.
2. C12H22O11 + H2SO4 = 12C+11H2O+H2SO4
3. How the substance get bigger.
what make the substance smoke.
if it make the substance bigger if you pour more chemical               liquid.
what will happen if we put more sugar in it.

1. if we increased the temperature, but decrease the concertation is the reaction rate will be fast or slow.

collision theory is closely related to kinetic molecular theory. this explains how all matter is made of particles, and those particles are in constant motion. as they move around, sometimes they collide into one another. if they collide in the right orientation, and with enough energy, the particles will rearrange in new combinations hence then a reaction will occur.
spontaneous is when the formation of products is favored at a given set of conditions.

1).  2 H2O2 (aq) → 2 H2O (l) + O2 (g)

2). It's a type of decomposing

3). In exothermic reactions, more energy is released when the bonds are formed in the products that are used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in the temperature of the reaction mixture.

4). Hydrogen peroxide is unstable and breaks down over time into water and oxygen gas, but the catalyst potassium iodide speeds up that decomposition in a matter of seconds.

the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles.

The units of molar mass are grams per mole can it be different than grams per mole?

Reactants VS Products

Reactants and Products are the two major components of a chemical reaction. Reactants are the starting material of a chemical reaction. Products are the chemical are produced in the reaction.

a). ~10g sodium bicarbonate
~20g calcium chloride
starting temp = 26C
final temp 22C
Starting mass = 68.9g
Final mass = 66.5g
water= 20mm
phenolphthalein (little a bit)
c). the gas/air in the back is starting to increase and the bubbles in the back is starting to form.

1. why the water turn to cold immediately.
2. how the red water goes through the flask.
3. why gas suddenly disappears.
4. why the temperature cool down
5. why did the temperature cool down.
6. If the temperature of a fixed amount of gas is doubled at constant volume, what happens to the pressure?
7. If the shape of the container affects the results?
8. Why does all the water get sucked into the flask?
9. How does the temperature change rapidly from the hot flask to room temperature?
10. Does this experiment work with another type of liquid?

So, today we talk about the trend of the periodic table and answering about the electronegative question

# data[].attributes.body
Today, we learned about the part of the periodic table and naming the part of it. Moreover, we also started with practice with the identifying the valence electron.

# data[].attributes.body
We learn about how to know the valence electron by the group that it in and we also learn a little bit of dot diagram.
