<span>Pillow lavas have pillow-like structures and are formations that push lava on the surface of the earth underwater. Magma comes out of ocean ridges as pillow lava and forms a new oceanic crust, supporting sea floor spreading. The older crust gets pushed away from the ridge and pushes on to the continents, making them drift.</span>
There are four major components found in wood, and these
are:
cellulose
lignin
starch
protein
Among the four, I believe that cellulose and lignin are
the most difficult to degrade because they contain large amount of cross-linked
heavy hydrocarbons.
Answer:
cellulose
lignin
<em>"Sedimentary rocks are formed by the pressure over millions of years of organic material, inorganic material, sediment of course , and earth piling up over itself. Metamorphic rock and igneous rock originate either below the surface where plants lived and creatures roamed, or the heat from volcanic activity transformed everything. Sedimentary rock formation is the only geologic activity that permits and allows organic material preservation and hence fossil formation." </em>- <u>Charles Snider, Co-Founder of American Geode (on Quora.com)</u>
Answer:
45.77 × 10²³ atoms
Explanation:
Given data:
Number of moles of iron = 7.6 mol
Number of atoms = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
7.6 mol × 6.022 × 10²³ atoms / 1 mol
45.77 × 10²³ atoms
The reported number of moles will be too low since the additional amount of oxygen is not included. It may be 6 drops but the molarity of the solution is 6M. this meas that for every ml of the JNO3 solution there is 6 moles of JNO3. In every mole of <span>JNO3 there are 3 moles of oxygen. So in every drop of oxygen there are 18 moles of oxygen. </span>
