Record your evidence about the Moon's appearance

Answer:

A solar eclipse .

It is one that occurs when the moon gets between the Earth and the Sun and it casts its shadow over the Earth. A solar eclipse only happens during the phase of new moon when the moon is indirect blockage of sun rays from reaching the earth thus causing a full shadow of the moon to fall on the Earth’s surface.

2 A lunar eclipse can only occur when there is a full moon. An eclipse of the moon happens only at full moon and only when the moon passes through some portion of the Earth’s shadow. The shadow in made of a two cone-shaped components, one which is nested inside the other.

3.  Earth blocks sunlight from reaching the moon's surface. There are three categories of lunar eclipse according to the blockage of the sun rays. In a penumbral lunar eclipse, the moon passes through Earth’s penumbral shadow. The partial lunar eclipse occurs when a portion of the moon passes through Earth’s umbral shadow. The total lunar eclipse happens when the entire moon passes through Earth’s umbral shadow.

4.When an object in space comes between the sun and earth. It is one that occurs when the moon gets between the Earth and the Sun and it casts its shadow over the Earth. A solar eclipse only happens during the phase of new moon when the moon is indirect blockage of sun rays from reaching the earth thus causing a full shadow of the moon to fall on the Earth’s surface.

5.A total lunar eclipse. In this type of lunar eclipse, the events are clearly visible and striking to view because the Moon surface appear red in color. During the occurrence of the lunar eclipse events, 35% of the entire eclipse is total eclipse.

6. Wide, dark areas and strange spots and ridges –Galileo described the surface of the moon as being uneven and rough. In addition to that, he described the surface as crowded with depressions and bulges. In his original sketches, the long shadows cast by craters were represented by dark sided of the moon sketch.

7. Waxing gibbous .During the cycle of the moon, it undergoes several phases; new moon-new crescent-first quarter-waxing gibbous-full moon-waning gibbous-last quarter-old crescent-new moon. The new moon phase cannot be seen because the part receiving sun rays in then pointed away from the earth. The rest of the phases are visible from the earth.

8. New moon .

During the cycle of the moon, it undergoes several phases; new moon-new crescent-first quarter-waxing gibbous-full moon-waning gibbous-last quarter-old crescent-new moon. The new moon phase cannot be seen because the part receiving sun rays in then pointed away from the earth. The rest of the phases are visible from the earth.

9. Because the Southern Hemisphere has more direct sunlight .During the winter months, the Northern Hemisphere is tilted away from the sun, thus it receive sunrays at an angle thus it experiences the cold weather. At this period, it is summer in the Southern Hemisphere.

Sabendo que os calores de combustão do enxofre monoclínico e do enxofre rômbico são, respectivamente, - 297,2 kJ/mol e - 296,8 k
liq [111]

Responda:

+ 0,9kJ / mol

Explicação:

Dados os calores de combustão do enxofre monoclínico e enxofre rômbico como - 297,2 kJ / mol e - 296,8 kJ / mol, respectivamente para a variação na transformação de 1 mol de enxofre rômbico em enxofre monoclínico conforme mostrado pela equação;

S (mon.) + O2 (g) -> SO2 (g)

Uma vez que são todos 1 mol cada, a mudança na entalpia será expressa como ∆H = ∆H2-∆H1

Dado ∆H2 = -296,8kJ / mol

∆H1 = -297,2kJ / mol

∆H = -296,8 - (- 297,2)

∆H = -296,8 + 297,2

∆H = 297,2-296,8

∆H = + 0,9kJ / mol

Portanto, a mudança na entalpia da equação é + 0,9kJ / mol

The balanced equation for the reaction between iron sulfied and water is best represented by?​
nika2105 [10]

FeS  +   H₂O    →    FeO   +    H₂S

Explanation:

  Iron Sulfide = FeS

  Water = H₂O

                FeS  +   H₂O    →    FeO   +    H₂S

To balance this equation, we can use a mathematical method. This involves solving simple algebraic equations

                 aFeS  +   bH₂O    →    cFeO   +    dH₂S

 a,b,c and d are the coefficients needed to balance up the equation:

      Conserving Fe: a = c

                           S:  a = d

                           H:  2b = 2d

                           O:  b = c

let a = 1, c= 1, b = 1 d = 1

     The balanced equation is:  FeS  +   H₂O    →    FeO   +    H₂S

What is the osmotic pressure in atm of
Dmitrij [34]

Answer:

12.2329 atm

Explanation:

Applying

PV = nRT.................... Equation 1

Make P the subject of the equation

P = (n/V)RT................ Equation 2

Where P = Osmotic pressure, (n/V) = Molarity of urea, T = Temperature, R = molar gas constant.

From the question,

Given: (n/V) = 0.5 M, T = 25°C = (273+25) = 298 K, R = 0.0821 Latm/mol.K

Substitute these values into equation 2

P = (0.5)(298)(0.0821)

P = 12.2329 atm
