A filmmaker wants to depict a realistic dramatization of a scientist making and communicating an important scientific discovery. Which plot description would best depict the methods of discovery and communication that a modern professional scientist uses? A. The scientist collaborates with others to plan and carry out an experiment and then writes a paper that has a clear conclusion. He submits it to a professional journal for peer review, after which the results are presented publicly.
B. The scientist works with a few other scientists in a secret lab that is sponsored by a large business corporation. When the scientists have results, they contact others in the scientific community to report their results.
C. The scientist works alone in a lab until he makes a dramatic breakthrough and then immediately announces the results through a worldwide press conference.
D. The scientist seeks input and data from a wide range of people of different scientific backgrounds and then publishes all the data and results on the Internet so that all the collaborators can apply it to their individual research.

Which form of relativism states that people rely on their own standards of right and wrong when making a decision?

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.

An excess of lithium oxide undergoes a synthesis reaction with water to produce lithium hydroxide li2o+h2o→2lioh if 1.05 g of water reacted, what is the theoretical yield of lithium hydroxide? a) 5.83 x 10–2 g lioh b) 1.17 x 10–1 g lioh c) 2.79 x 100 g lioh d) 1.40 x 100 g lioh
