Compounds lab report instructions: in this virtual lab you will build chemical compounds from known elements. record your hypothesis and compound results in the lab report below. you will submit your completed report to your instructor. note: if you cannot complete this lab as directed, contact your instructor for assistance. name and title: include your name, instructor's name, date, and name of lab. objectives(s): in your own words, what is the purpose of this lab? hypothesis: in this section, include the if/then statements you developed during your lab activity. these statements reflect your predicted outcomes for the experiment. procedure: the materials and procedures are listed in your virtual lab. you do not need to repeat them here. however, you should note if you experienced any errors or other factors that might affect your outcome. using your summary questions at the end of your virtual lab activity, clearly define the dependent and independent variables of the experiment. data: record the composition of each of your compounds below. be sure to include the number of atoms for each element. an example has been supplied for you. compound name chemical formula sodium (na) atoms calcium (ca) atoms hydrogen (h) atoms oxygen (o) atoms carbon (c) atoms chlorine (cl) atoms ex: sodium hypochlorite naclo 1 0 0 1 0 1 conclusion: your conclusion will include a summary of the lab results and an interpretation of the results. answer all questions in complete sentences using your own words. using two to three sentences, summarize what you investigated and observed in this lab. why do you believe knowing how elements and compounds react together is essential in everyday matters? some elements are more "reactive" than other elements; why do you think this is? choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
