Closed Plastic Bottle Experiment
1. The topic I’m doing my experiment on is chemical reactions. In my experiment I will mix baking soda and vinegar in a closed plastic bottle. I hypothesize that when the baking soda and vinegar mix gas will form and start filling up the bottle eventually leading to a small explosion. The dependent variable is the product of the chemical reaction and the formation of gas filling up the bottle eventually causing an explosion. The independent variable is the baking soda and vinegar react. My control conditions are a water bottle that is about 8 inches in height and about 3 inches in width and I will use about 6 grams of baking soda and ½ a cup of vinegar. I will put protective glasses to avoid damage to my eyes and I will first pour the vinegar …show more content…
Mendeleev’s periodic table in the order of increasing atomic masses of the elements. Mendeleev also organized elements in columns depending on how they react. Moseley’s table is arranged in the order of increasing atomic numbers.
8. The element is cobalt and its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d7 4s2.
9. There is only one electron in copper’s highest energy orbital.
10. Arsenic should have five dots on its electron dot structure because it has five electrons in its outermost shell.
11. There are two reasons why nonmetals have higher ionization energy than alkali metals. The first reason is that the alkali metals have a larger atomic size than the nonmetals, so they have more trouble attracting electrons. The second reason is that the nonmetals have smaller atomic sizes making it easy to attract electrons but difficult to pull them away.
12. A lot of energy is required to break a strong intermolecular bond. This is because atoms in certain compounds have very strong bonds that require energy to break. This explains why some compounds have higher boiling points than others.
13. Fe2(SO4)3
14. Group 13 metals usually have charges of 3+ because they tend to lose the electrons in their outermost
Salt Creek And Barker Lake Lab Report
566 Words | 3 PagesIn this lab we were trying to figure out if Salt Creek and Barker Lake had the correct chemical balances to sustain catfish for the years coming. In order to find this out, we tested the water using a Hach Water Testing Kit. Inside were dissolved oxygen reagent powder pillows 1, 2 and 3 which we added and mixed into our sample water to prepare it for testing. Then we added droplets of Sodium Thiosulphate Solution into the prepared water too see how much dissolved oxygen parts per million were in the water. Our independent variable in this experiment was the 5 different testing sites that we went to for water samples.

P1 Task 1
415 Words | 2 PagesIonizing energy also increases as the elements go across the periods and also decreases when the elements go down the groups. The atomic radius does the opposite of electronegativity and ionization; it decreases as the elements go across the periods and increases when the elements go down the groups. The electronegativity increases as you go across the periods because the elements nucleus gains 1 more proton which means more protons more power to attract the electrons, the electronegativity decreases as you go down the groups because an extra shell is added every time this then causes an increase in nuclear charge due to more protons being added. This means that the nucleus is less able to attract electrons. Ionizing energy increases across a period because as the atoms radii is getting smaller the electrons get closer to the nucleus which creates a greater attraction for the electrons making it harder to remove them.

Bath Bomb Hypothesis
667 Words | 3 PagesDeveloping a topic for Science Fair will never be easy unless you have a little background about that certain topic. One particular scientist is developing her topic by researching questions she has that revolved around her topic. The scientist will be researching how water temperature can affect the chemical reaction rate between baking soda and citric acid within a bath bomb. The independent variable will be the temperature of the water (mL). The dependent variable will be the chemical reaction rate which is formed by baking soda (g) and citric acid (g).
Alka Seltzer Experiment
794 Words | 4 PagesIn this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of
How Fast Does Alka Seltzer Make Gas
621 Words | 3 PagesThe topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound.
How Does The Amount Of Baking Soda Mixed With Vinegar Affect The Volume Of Gas Produced?
1211 Words | 5 PagesHow does the amount of baking soda mixed with vinegar affect the volume of gas produced per 10 seconds? A reaction is when (usually) a solute acts on a solvent to create a reaction. An example of a reaction is an explosion, Here we will be using baking soda and vinegar which are our two components which will cause for a reaction to take place. Reactions can be affected by several things such as temperature, concentration and the presence or absence of a catalyst which is a substance which can increase the rate of reaction.
