________ is a strong, parallel alignment of coarse mica flakes and/or of different mineral bands in a metamorphic rock.
kari74 [83]

Answer:

Foliation is a strong, parallel alignment of coarse mica flakes and/or of different mineral bands in a metamorphic rock.

Explanation:

Foliation is most commonly prevalent in metamorphic rocks. Foliation is the parallel alignment of textural and structural features of a rock.

Differential stress plays a major role on the texture of metamorphic rocks because it forces the mineral constituent of the rocks to align parallel to each other.  Foliation can occur in different ways for example a mineral like mica which is usually platy can crystallize in rocks , due to differential stress the mineral grows in such a way it remains parallel to the movement in which the part of the rock slide relative to one another and parallel to the forces applied or the mineral might grow perpendicular to the direction of the compressed stress.  

Notice the foliation in the texture of gneiss .You can see the light and dark mineral found in separate or parallel layer.

Describe un modelo matemático para representar lo que sucede en cada una de las reacciones químicas  (incluye toda la simbología
GuDViN [60]

Responder:

2H2 + O2 → 2H2O

CaO + H2O → Ca (OH) 2

Fe + S → FeS

H2SO3 → SO2 + H2O

CaCO3 → CaO + CO2

Explicación:

2H2 + O2 → 2H2O

2 moléculas de hidrógeno gaseoso reaccionan con oxigente para producir 2 moléculas de agua

CaO + H2O → Ca (OH) 2

El óxido de calcio reacciona con el agua para producir hidróxido de calcio.

Fe + S → FeS

El hierro reacciona con el azufre para producir sulfuro de hierro.

H2SO3 → SO2 + H2O

Por descomposición, el ácido sulfuroso se descompone para producir dióxido de azufre y agua.

CaCO3 → CaO + CO2

El carbonato de calcio se descompone para producir óxido de calcio y dióxido de carbono.

If a gas at 25.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm?
Greeley [361]

Answer:

1.44 L

Explanation:

Since 25 is constant it is no use. Now, rearrange the gas formula. You should get...

P1V1/T2=P2V2T1

Next, rearrange to fit the problem. You should get...

V2=P1V1/P2

Fill in our values and solve. You should get 1.44 L

We can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.

- Hope that helps! Please let me know if you need further explanation.
