All rocks on Earth are eventually recycled into another type. In between the rock, types are different forms of materials, such as sediment and magma. The processes that cycle Earth’s materials over time are collectively called the rock cycle. Which of the following best describes the flow of energy that drives the processes of the rock cycle? Select all that apply

A) Energy from Earth’s hot interior produces magma which then cools

and crystallizes into igneous rock.

B) Energy from the Sun produces lava on Earth’s surface which can cool

and crystallize into igneous rock.

C) Energy from Earth’s hot interior causes extreme temperatures and

pressure to change igneous, sedimentary, and metamorphic rocks

into new metamorphic rocks.

D) Energy from the Sun causes wind and water movement, causing

weathering and erosion of rocks and the production of sediments

E) Energy from Earth’s hot interior produces sediments which then

compact and cement into sedimentary rock.

F) Energy from the Sun causes wind and water movement to carry and

deposit sediments, which can eventually form sedimentary rocks.

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.

What is the percent composition of ca(oh)2? 37.7% ca, 53.0% o, and 10.3% h 45.5% ca, 38.2% o, and 16.3% h 54.0% ca, 43.0% o, and 2.7% h 64.7% ca, 27.0% o, and 8.3% h
