Answer:

Schist is not an example of sedimentary rocks.

Explanation:

Sedimentary rocks are formed by the continual deposition of small particles carried in rivers and deposited in lakes or oceans which are subsequently cemented over time due to pressure from the upper layers and presence of some minerals at the Earth's surface. They are majorly in layers and the three types are; organic, chemical and clastic. Common examples are; sandstone, limestone, and shale.

The answer is option B "schist." Schist is a metamorphic rock and metamorphic rocks are formed by intense heat and pressure. It wouldn't be options A, C, or D because these are indeed sedimentary rocks which are formed by deposition and compaction.

Hope this helps.

Usimov [2.4K]

Answer:

Water moves from the ground or oceans into the atmosphere through a process called evaporation. It's a process that happens on a molecular level when the molecules of water are really energized and rise into the air. Now you've got water in the air and water on land. Organisms all over the Earth need water to survive.

The formation constant for the reaction ag (aq) 2nh3(aq) ag(nh3)2 (aq) is kf = 1.7 × 107 at 25°c. what is δg° at this temperatur
anzhelika [568]

The value of ΔG° at this temperature is -18034.18 J/mol

Calculation,

Given information

formation constant (Kf)= 1.7 × 10^{7}

Universal gas constant (R) = 8.314 J/K• mol

Temperature = 25° C = 25 °C + 273 = 300 K

Formula used:

ΔG° = -RT㏑Kf

By putting the valur of R,T, Kf we get the value of ΔG°

ΔG° = - 8.314 J/K• mol×300K㏑ 1.7 × 10^{7}

ΔG° = -2494.2㏑ 1.7 × 10^{7} = -18034.18 J/mol

So, change in standard Gibbs's free energy is -18034.18 J/mol

What is the unit for volume?
kondaur [170]

The answer is volume because The base units of length and volume are linked in the metric system. By definition, a liter is equal to the volume of a cube exactly 10 cm tall, 10 cm long, and 10 cm wide. Because the volume of this cube is 1000 cubic centimeters and a liter contains 1000 milliliters, 1 milliliter is equivalent to 1 cubic centimeter.

Hope this helps :)
