Please answer all questions in this exam. Answers to the multiple choice questions need to be filled in on the scantron sheets (remember to use pencil to fill in the circles) and also circled on the exam itself. Answers to the short answer questions should go in the exam booklet provided. All three components (scantron sheets, exam booklets, paper copy of exam) should be turned in at the conclusion of the exam.

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

The reaction between Copper (II) Chloride and aluminum has a formula that follows this basic single replacement formula. Aluminum was able to replace copper during the reaction because it is higher on the activity series. If aluminum

Despite a family history of geophysicists and rock enthusiasts, I’ve never found the subject of rocks particularly fascinating. However, an exploration of Earth Science has lead me to the discovery that rocks are actually hidden gems (often literally), and that there’s more to the topic than one would think.

1 Write your name and student number on the top of this examination paper and on ALL answer booklets.

If necessary, use the back of the exam pages for the rest of your answers. Do not use other sheets of paper. Please write legibly; if I cannot read your answer, I will count it wrong.

问题 19 0.8 分 In order for frost action to get started ______________ must be present in the rock.

With volume and mass determined, the density formula (d = m/V) was used to determine the densities of each rock and recorded in g/ml.

15) A cart starts from rest and accelerates at 4.0 m/s2 for 5.0 s, then maintain that velocity for 10 s, and then decelerates at the rate of 2.0 m/s2 for 4.0 s. What is the final speed of the car?

4. Choose one of the geological periods listed in figure 3.8 and find out all you can about it. How are rock formations from that period identified? What are its most characteristic fossils? Where are the best samples of rock from your chosen period?

Copper starts to dissolve and bubbling occurs when nitric acid was added. The solution became green and the beaker started to become orange/brown as gas was being released. Solution then became light blue when washed with water.

I started with elemental copper metal and then reactions occur step by step as follows:

The purpose of this lab was to evaluate our skills of decanting a supernatant liquid without losing the solid and successful completion of a series of reactions. This was done through five chemical reactions involving copper. In this lab, elemental copper was put through five different chemical reactions in order to convert it into different compounds. By the end of the fifth reaction, the copper was back to its elemental state.

And copper (II) ions were reduced to copper because it gained electrons and its oxidation number changed from +2 in copper (II) ions to 0 in copper.
