write a summary about the moon phases

Answers

Answer:

A lunar phase is simply the shape of the sunlit part of the Moon, as seen from Earth. Phases are so strikingly obvious that we almost take them for granted. Moreover, they can be observed easily throughout the month from the backyard or via a simple glance out the window.

The Moon's shape changes for the following reasons:

The Moon orbits Earth.

Both Earth and the Moon orbit the Sun.

The Moon's orbit is the same length as the time it spins on its axis (about 28 Earth days), which means that we see the same part of the lunar surface all month.

The Sun illuminates both Earth and the Moon.

Get to Know the Lunar Phases

There are eight phases of the Moon to track each month.

New Moon: During New Moon, the side of the Moon facing us is not illuminated by the Sun. At this time, the Moon is not up at night, but it is up during the day. We just can't see it. Solar eclipses can occur during the New Moon, depending on how the Sun, Earth, and Moon line up in their orbits.

Waxing Crescent: As the Moon waxes (grows) into its crescent phase, it begins to show up low in the sky right after sunset. Look for a silvery-looking crescent. The side facing the sunset direction will be lit up.

First Quarter: Seven days after New Moon, the Moon is in first quarter. Only half of it is visible for the first half of the evening, and then it sets.

Waxing Gibbous: After First Quarter, the Moon appears to grow into a gibbous shape. Most of it is visible, except for a dark sliver that shrinks over the next seven nights. Look for the Moon at this time during the afternoon, too.

Full Moon: During the Full Moon, the Sun lights up the entire surface of the Moon that faces Earth. It rises just as the Sun sets and disappears beneath the western horizon when the Sun rises the next morning. This is the brightest phase of the Moon and it washes out the nearby part of the sky, making it difficult to see stars and faint objects such as nebulae.

Ever hear of a Super Moon? That's a Full Moon that happens when the Moon is closest in its orbit to Earth. The press likes to make a big deal about this, but it's really a very natural thing: On occasion, the Moon's orbit brings it closer to Earth. Not every month has a Super Moon. Despite the hype about Super Moons in the media, it's difficult for the average observer to notice one, because the Moon might appear only slightly larger in the sky than normal. In fact, the well-known astronomer Neil deGrasse Tyson pointed out that the difference between a regular Full Moon and a Super Moon is analogous to the difference between a 16-inch pizza and a 16.1-inch pizza.

Lunar eclipses occur only at Full Moons because the Moon is passing directly between Earth and the Sun in its orbit. Due to other perturbations in its orbit, not every Full Moon results in an eclipse.

The other Full Moon variation that often grabs media attention is a "Blue Moon." That's the name given to the second Full Moon that occurs in the same month. These don't happen all the time, and the Moon certainly doesn't appear blue. Full Moons also have colloquial names based on folklore. It's worth reading about some of these names; they tell fascinating stories about early cultures.

Waning Gibbous: After the glorious appearance of Full Moon, the lunar shape starts to wane, meaning it gets smaller. It's visible later at night and into the early morning, and we see a steadily shrinking shape of the lunar surface that's being lit up. The side that is lit up is facing toward the Sun, in this case, the sunrise direction. During this phase, look for the Moon during the day—it should be in the sky in the morning.

Last Quarter: At Last Quarter, we see exactly half the sunlit surface of the Moon. It can be seen in the early morning and daytime sky.

Waning Crescent: The last phase of the Moon before returning to New Moon is called Waning Crescent, and it is exactly what it says: a steadily-shrinking crescent phase. We can see only a small sliver from Earth. It's visible in the early morning, and by the end of the 28-day lunar cycle, it has vanished almost entirely. That brings us back to New Moon to start the new cycle.

Citation for work-Petersen, Carolyn Collins. "The Once-Mysterious Phases of the Moon Explained." ThoughtCo, Aug. 27, 2020, thoughtco.com/what-are-moon-phases-3883581.

Explanation:  

Something shorter-The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon. Each phase repeats itself every 29.5 days. The same half of the Moon always faces the Earth, because of tidal locking. So the phases will always occur over the same half of the Moon's surface.

Answer:

Limiting: Lab covers. Books produced: 75. Excess amounts: In explanation

Explanation:

Amount that can be produced with just lab covers: 75 books (150/2)

Amount that can be produced with just lined paper: 150 books (7500/50)

Amount that can be produced with graph paper: 120 (3000/25)

Amount that can be produced with staples: Approximately 83 (250/3)

As we can see, the lab covers are limiting as they can only produce 75 books. So, we can only make 75 books.

You will have 3,750 lined paper left over (or 75 books)

(150-75=75 , 75*50=3,750)

You will have 1,125 graph paper left over (or 45 books)

(120-75=45 , 75*25=1,875 , 3000-1875=1125)

And then you will have approximately 25 staples left over (or 8 books)

(83-75=8 , 8*3=225, 250-225=25)

(Hopefully this is correct, I apologize if I messed up)

Given the following data:

Accepted value = 524 degrees

Experimental value = 546 degrees

To find the percentage error;

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

[tex] Percent \; error = \frac {accepted \;value - experimental \; value}{ accepted \;value} *100[/tex]

Substituting into the equation, we have;

[tex] Percent \; error = \frac {524 - 546}{ 524} *100[/tex]

[tex] Percent \; error = \frac {22}{524} *100[/tex]

Note: the negative sign is ignored when calculating percentage error.

[tex] Percent \; error = 0.04199 *100[/tex]

Percent error = 4.199 ≈ 4.2%

Ammonium chloride, ammonium sulfate and ammonium nitrate are used in fertilisers.
Ammonia reacts with nitric acid to make ammonium nitrate.
NH3 + HNO3 → NH4NO3
Calculate the mass of ammonia required to make 5.0 g of ammonium nitrate.
relative formula mass of NH3 = 17
relative formula mass of NH4NO3 = 80

Answers

Answer:

1.0625 g

Explanation:

Number of moles in 5g of NH4NO3 = 5.0g/80g/mol = 0.0625 moles

Again the balanced reaction equation is;

NH3 + HNO3 → NH4NO3

So,

1 mole of NH3 yields 1 mole of NH4NO3

x moles of NH3 yields 0.0625 moles of NH4NO3

x = 0.0625 moles of NH3

Mass of NH3 = number of moles * molar mass

Mass of NH3 = 0.0625 moles * 17g/mol

Mass of NH3 = 1.0625 g

How many silver atoms are in 1 mole of silver?

b. Nothing can be inferred because the temperature of the system may have been changed
c. The rate of the reverse reaction is greater than the rate of the forward reaction
d. The rate of the forward reaction is greater than the rate of the reverse reaction.

Answers

Answer:

The answer is D. The rate of the forward reaction is greater than the rate of the reverse reaction.

Explanation:

The forward reaction rate was greater than the reverse reaction rate because more product is present at time 2. This is the answer from ap classroom.

The given reaction has been inferred the increased rate of forward reaction than reverse reaction. Thus, option D is correct.

The chemical reaction has been given by the combination of reactants for the formation of product. The reactants combine in the fixed proportion to form the product.

The rate of reaction has been defined as the rate of formation of product or the disappearance of reactants.

Rate of reaction

The forward reaction has been given as the rate of formation of product. The reverse reaction has been given as the rate of dissociation of product.

In the given condition, the number of reactant at time 1 are more than the reactant at time 2. This states that there has been increased formation of the product at time 2.

Thus, the given reaction has been inferred the increased rate of forward reaction than reverse reaction. Thus, option D is correct.
