1. ReShayla was making pancakes and decided that she wanted hot syrup on her pancakes. As she poured the syrup into a bowl, it came out slowly. After she heated it in the
microwave for a few seconds, she poured the syrup onto her pancakes and it came out
quickly. Why did the syrup come out quicker after she warmed it up?
a. Its surface tension decreased because the radiation from the microwave broke the
intermolecular forces it had.
b. The radiation from the microwave increased its viscosity by breaking the syrup's
intermolecular forces.
c. Its surface tension increased because the radiation from the microwave broke the
intermolecular forces it had.
d. The radiation from the microwave decreased its viscosity by breaking the syrup's
intermolecular forces.

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.

The earth's surface is (science) a: studied using seismic waves b: constantly changing over time c: only studied indirectly d: the same today as million of years
