The shape of an ammonia molecule is trigonal pyramidal (see the image below).
The N atom is at the top of the pyramid and the three H atoms are at the corners of a triangular base.
To determine the amount of a substance in units of moles from units of grams, we need to determine the molar mass of the substance. <span>The </span>molar mass<span> is the </span>mass<span> of a given chemical element or chemical compound (g) divided by the amount of substance (mol). For CuF2, the molar mass </span><span>101.543 g/mol. We calculate as follows:
100.0 g CuF2 ( 1 mol / 101.543 g) = 0.98 mol CuF2</span>
Hey there!
Here is your answer:
<u><em>The proper answer to this question is "pressure, deposition, and compaction".</em></u>
Reason:
<u><em>Sedimentary are formed by pressure, deposition, compaction. Which should be in one of your answer choices.</em></u>
Also....
<u><em>This would help you strike out options you don't need, igneous rocks are formed by cooling of magma or lava, and metamorphic rocks are formed by heat and pressure under the Earths surface.</em></u>
If you need anymore help feel free to ask me!
Hope this helps!
