When Raymond observes certain natural phenomena, he often forms Ideas about their causes and effects. Suppose that Raymond
surmises that leaves change color in autumn due to scarcity of sunlight. In order to test whether his idea is accurate, he must first
construct a falsifiable 1.)
that defines a clear relationship between two variables. Raymond's next step is to 2.)
that would Isolate and test the relationship between the two variables. This task can be pretty
daunting because Raymond will need to identify and eliminate any 3.)
variables that could confuse test results.

1.)
A.) theory
B.) law
C.) hypothesis

2.)
A.) design an experiment
B.)complete mathematical calculations
C.) propose an explanation

3.)
A.) confounding
B.) dependent
C.) independent

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.

1. explain hydrogen peroxide, h 2 o 2 properties and decomposition reaction. 2. describe how each of the following natural cycles plays a part in earth’s climate system. (a) the water cycle (b) the carbon cycle
