Mechanical waves react to different mediums in different ways. Some mechanical waves are through a medium, meaning they pass through the medium. The way in which waves are transmitted depends upon the type of material. In , mechanical waves travel rapidly, because the molecules are packed. In liquids and air, however, mechanical waves travel more , because the molecules are spread farther apart.

Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it off the medium and then travels in a direction. is an application that uses sound wave reflection to determine how deep water is. A third way mechanical waves react to a medium is . When a mechanical wave is absorbed, it remains a medium and is not transmitted to another medium.

tbh shawty I dont have the brains for this when I read this I read absorption as abortion

first, consult an activity series chart to determine if al is more reactive than fe. it is, so it will replace the fe. now, one can continue with the problem.

next, make sure you have a correctly balanced equation.

3feo + 2al ==> 3fe + al2o3

now, determine which reactant (feo or al) is in limiting supply.

moles feo present = 125 g x 1 mole/71.8 g = 1.74 moles

moles al present = 25.0 g x 1 mole/26.98 g = 0.927 moles

since from the balanced equation, it take 3 mol feo for every 2 mol al, al will be limiting.

you can determine this simply by dividing moles of each by their coefficient in the balanced equation. for example: 1.74/3 = 0.58 and 0.927/2 = 0.464. al is less, so it is limiting.

finally, using the stoichiometry in the balanced eq. determine mass of fe that can be produced from 0.927 moles of al.

0.927 moles al x 3 moles fe/2 moles al x 55.8 g/mole = 77.6 g

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
