Description For part two you will simply continue to measure and graph the behavior from baseline but now you are applying the contingency. You need to provide the graph and a description of your specific contingency statement describing how and when the contingency would be delivered. You will need to provide an interpretation as to whether your intervention worked and if you will decide to return to the baseline contingency or if you will need to try a new contingency for part 3 of the project.
Description This exercise uses Chapter 9: Data Set 1. Using the NORM.S.DIST function, compute the probability for the first raw score in Cell A2 and then copy the function down to compute the probabilities for each corresponding z-score. (Worksheet 1)
Description Discussion: Animal Adaptations How do animals that live in extreme winter environments survive below-freezing temperatures? Many hibernate or migrate to warmer climates, but an amazing few have actually adapted "freeze tolerance" mechanisms that enable them to survive without additional protection. Freeze tolerance takes advantage of the colligative property of freezing point depression. How does it work? See what you can dig up about freeze tolerance in animals: What is one animal with freeze tolerance and in what kind of habitat does it live? How does the animal use the property of freezing point depression to survive? (Be specific!)
Description Assignment: Properties For each of the objects list six physical properties of the object. Identify each property as extensive (E) or intensive (I) and describe how you know it is an intensive or extensive physical property. Then, select one property you identified for each object and describe, in detail, how you would test that property. For example, if you determined that a metal rod is very dense, how would you measure its density?
Description QUESTION 1 Oxidation-reduction reactions are reactions in which: protons are transferred from one reactant to another electrons are transferred within the same atom electrons are transferred from one reactant to another oxygen molecules must participate 3 points Save Answer QUESTION 2 In a reaction, oxidation can occur independently of reduction. TRUE FALSE 2 points Save Answer QUESTION 3 Preventing the rusting of iron is a major industry. Which of the following methods would NOT control the amount of iron corrosion? keep the iron sample dry coat the iron sample with a waterproof coating place a sacrificial electrode in contact with the iron bathe the iron in a weakly acidic solution 3 points Save Answer QUESTION 4 The oxidation number of an atom of a free element is always 1. TRUE FALSE 2 points Save Answer QUESTION 5 In their compounds, metals: are assigned positive oxidation numbers are assigned negative oxidation numbers are assigned oxidation numbers of zero can be assigned any oxidation number that balances the equation 3 points Save Answer QUESTION 6 In the reaction, C + 2 S Imported Asset CS2, the substance that is the oxidizing agent is: the C the S the CS2 both the C and the S 3 points Save Answer QUESTION 7 In the reaction, 2 Al (s) + 3 Sn+2 (aq) Imported Asset 2 Al+3 (aq) + 3 Sn (s), the reducing agent is: the Al the Sn+2 the Al+3 the Sn 3 points Save Answer QUESTION 8 How many electrons should be added to balance the following oxidation half-reaction, H2O2 Imported Asset 2 H+ + O2? None One Two Four 3 points Save Answer QUESTION 9 When balancing the oxidation and reduction half-reactions for basic solutions, you should: use H+ and OH? equally in order to balance the equation use H+ only in order to balance the equation use H+ and H2O, as needed to balance the equation use OH? and H2O, as needed to balance the equation 3 points Save Answer QUESTION 10 Electrochemical reactions are oxidation-reduction reactions that: are capable of generating electric current have unequal oxidation numbers on both sides of the equation only generate the oxidation reaction only generate the reduction reaction 3 points Save Answer QUESTION 11 The voltaic cell produces electric current from a spontaneous chemical reaction, but electrolytic reactions are not spontaneous. TRUE FALSE
