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.

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.

Why does the freezing of water, exothermic process,become spontaneous at temperatures below 0° C even though the entropy of liquid water decreases during the phase change?
Answer:
Because the melting of ice as a spontaneous process (or reaction).
Explanation:
Here is an example:
Take a ice on a plate and leave it for half an hour (conditions). After half an hour, we notice water instead of ice.
This process took place without any intervention from your side. Heat absorbed by the ice from surrounding is due to set of conditions not due to your intervention.
So, we can consider melting of ice as a spontaneous process (or reaction).

What is the primary difference between two different isotopes?
Answer:
Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons.

Two people are playing tug of war. One person pulls to the right with 32 N of force. The other person pulls to the left with 37 N of force. How strong is the net force and in which direction?
Answer:
The net force is 5 N and to the left.
Explanation:
37 N - 32 N = 5 N and since there is a stronger pull from the rope moves towards the left so the direction of motion is left.

b) Why is aluminium extracted using electrolysis and not carbon?
Answer:
Aluminum is more reactive than carbon so it must be extracted from its compounds using electrolysis.
Explanation:
Even though aluminum is more abundant than iron in the Earth's crust, aluminum is more expensive than iron. This is mainly because of the large amounts of electrical energy used in the extraction process.
In your lab group you combined vinegar and water and observed the results shown in the picture. Choose ALL of the evidence that
supports that a chemical change has occurred.
A gas is produced.
B)The color changed.
c) Bubbling occurred.
D) The baking soda dissolved.
E) There is a change in the composition of the reactants.
ANOTHER HELP OVER HEREEEEEE PLSSSSSSS
The declaration made in the image's results indicates that a chemical shift has taken place. There occurs the creation of gas.
What occurred when you put vinegar in the water?This occurs as a result of vinegar's composition of acetic acid and water. Acetic acid and water molecules create robust connections. These bonds cause the molecules inside the solution to move more slowly than those in pure water, hastening the freezing of the solution.
Briefing:A cup of vinegar and a cup of warm water are the basic components of the vinegar cleaning solution. Grease as well as hard water stains are easier to remove with warm water. It may be best to combine the vinegar and distilled water rather than tap water when filling a spray container that will be used often.
To create a chemical reaction, what can you combine with vinegar?A chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) results in the production of salt (sodium acetate), water, and carbon dioxide gas.

if I have a +2 oxidation number do I give up or accept electrons?
Answer:
I will give up the electrons
Explanation:
Consider the following rules:
1. An atom loses electrons if its oxidation number is positive.
2. An atom gains electrons if its oxidation number is negative.
3. An atom neither gains nor loses electrons if its atomic number is zero.
As I have an oxidation number [tex]+2[/tex] that is oxidation number is positive, so, I will give up electrons.

An equimolar mixture of X (g) and Y (g) is placed inside a rigid container at constant temperature. The particle diagram above represents the changes that occur over time. Based on the particle
diagram, which of the following best predicts whether or not the system has reached equilibrium by 300 s?
a. It is not possible to determine that the system has reached equilibrium by 300 s because the stoichiometry of the reaction is not known.
b. it is not possible to determine that the system has reached equilibrium by 300 s because the amounts of X, Y, and XY have continued to change
c. The system has reached equilibrium by 300 s because the rate of formation of XY is constant
d. The system has reached equilibrium by 300 s because the rates of consumption of X and Y are equal
Answer:
B
Explanation:
t= 300s has more XY than t=200s, which means that it continues to change
*i think
The system has been predicted to be not possible to reach equilibrium as changing X and Y concentration. Thus, option B is correct.
Equilibrium has been described as the condition in the reaction mixture, when the concentration of the product and the reactant are equal.
The given reaction has been represented as:
[tex]\rm X+Y\rightarrow\;XY[/tex]
Reaction mixture at 300 sThe given reaction has been represented as, with the increase in time, there has been the consumption of the reactant and the formation of product.
The concentration has been continuously changing with time. Thus, the determination of the equilibrium has been difficult with changing X and Y concentration.
Thus, option B is correct.
