Exploring Reactivity and Periodicity

The question that we tried to answer with this lab was does reactivity a periodic property?

What we did to figure it out was test elements in their solid forms and putting them inside water to see how they react. Then we would put phenolphthalein as a base. The elements we used in solid form were sodium, potassium, calcium, magnesium, and copper. Then we made observations on how the elements reacted with water.

This are my observations:

Sodium- was moving like crazy on the water it was producing smoke and was making a sizzling noise. It changes the color of the water once we added the phenolphthalein. 

Potassium- literally exploded once it touched the water and we saw flame.It also changed the color of the water once we added the phenolphthalein.

Calcium-at first when we put it in the test tube with water there was a bit of fizzing. Then when we added the phenolphthalein the water changed color and then after a few minutes in a heater the mixture started bubbling up and if you touched it. It would give a shock and it felt hot.

Magnesium- nothing was happening until we added the phenolphthalein that changed the color of the water and made more bubbles be around the magnesium ribbon.

Copper- nothing changed even after adding the phenolphthalein.

Based on my observations I decided the reactivity of the elements from most reactive to least reactive. The order is  Potassium, Sodium, Calcium, Magnesium, Copper. 

Then I realized something as the orbitals levels go to a higher level the reactivity gets higher also. then i also realized that as farther the columns the least reactive it is the element. So that made me realized that reactivity is a periodic property.

3 quiestion blog 09/03/17

The task that I have completed recently in my class of chemistry have been 2 labs, and a pogil, regarding significant digits and significant digits calculations. The pogil we did was significant digits and measurements this was the first thing we did to learn the basics of significant digits and how there manipulated like if you have only centimeters and no millimeters you estimate to the tenths place like if it 5 centimeters you have to add a 5.0 centimeters but if it has a millimeters then its 5.12 the 2 is estimated. Then the lab we did was density of pennies where we calculated the volume of the pennies in a 100mL graduated cylinder by using significant digits. then we had a lab about figuring the thickness of aluminum and to do that we had to convert units. So the things i have learned recently is about significant digits, how to round them, how to calculate them, and how to convert units well that I still haven't got it completely. Finally,   to improve my understanding I

3 question blog #2

This was do a Friday and i didn't do it but now its here yay.      What i did in that  week was learning about chemical and physical changes we did labs to see the difference between the both were. what i learned was that a change in state is a physical change and for it to be a chemical change it has to get in mix with acid,fire,or two liquids turn into a solid (perspitant). What i did to improve in these subject was learn the basic things that made a chemical change and what made a physical change and examples of those.

Exploring Isotopes & Average Atomic Mass

The guiding question of this lab: What is the atomic mass of beanium? What I did during these lab was first i did this graph: Data Type of Bean Total number Total  Mass Average Mass Percent Limium 5 7.0g 1.4g 10% Kidneyum 15 8.0g 0.53g 30% Peagen   30 6.5g .22g 60% Then i got the mass of the total number of limium then i averaged it. Then repeated this for kidneyum and peagen. Then figured out there percentages. With the formula P/Wx100=%. Then i followed another formula to get the atomic mas for beanium, the formula was #1 average mass x 10% + #2 average mass x 30% + #3 average mass x 60% divided by 100. Which the answer was 0.431 g for the atomic mass for beanium. That's how I did this lab.
