Explanation:
There are some climates in which there are no living things. The average of the weather is the climate.
What is climate ?Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of climatic variables over a period of time that can range from a few months to many millions of years.
Every element of our life is impacted by the climate, including our food supplies, transportation systems, clothing choices, and vacation destinations. It significantly affects our future, our health, and our means of subsistence. Climate is the long-term trend of the weather in any given location.
As an illustration, you can anticipate snow in the Northeast in January or hot and muggy weather in the Southeast in July. Climate is this. Extreme values, such as record-breaking high temperatures or heavy rainfall, are also part of the climatic record.
Thus, there are some climates in which there are no living things.

How does a material get a negative charge?
Explanation:
When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.

write a summary about the moon phases
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:
B. X= Elements, Y= Compounds
Explanation:
An element is a substance that is made up of only one type of atom. The atoms of an element can combine together chemically to form a molecule but can still exist as an individual atom e.g. Hydrogen atom; H can form molecule H2. Since only one atom makes up an element, its electrons act independently.
Compounds, on the other hand, are substances that are made up of more than one type of atom chemically combined. A compound can only exist as a molecule because it always contains more than one atom bonded together. However, since more than one atom are involved in the chemical bond that holds them together, electrons are shared with other atoms. Example of a compound is H20 containing atoms of hydrogen and oxygen that are chemically combined.

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.

Balance the chemical equation. Based on the equation, how many grams of bromine are produced by the complete reaction of 11 grams of potassium bromide? Use the periodic table to get the weights of the elements. Carry out your calcuation in the same way as you did in parts A, B, and C. That is, begin by converting grams of KBr to moles of KBr, then use the mole ratio of KBr to Br2.
Answer:
Explanation:
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)
The balanced chemical equation is Cl₂ + 2 KBr → 2 KCl + Br₂.7.39 g of bromine are produced by the complete reaction of 11 grams of potassium bromide.
What is chemical equation?The Chemical equation is a symbolic representation of a chemical reaction is written in form of symbols and chemical formulas.The reactants are present on the left hand side while the products are written on the right hand side of the chemical equation.
A plus sign is written between reactants and products if they are more than one reactants or products in any case and an arrow is present which points towards the product side which indicates the direction of the reaction in which it is proceeding.There are coefficients present next to the chemical symbols and formulas .
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr which is 1 mole of KBr/119.002 g KBr × 1 mole of Br₂/2 mole KBr × 159.808 g Br₂/1 mole of Br₂= 7.39 g Br₂.
