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.

Answer: 5.6L

Explanation:

Just did it on an assignment

A 3.5L flexible container holds a gas at 250K. The new volume will be 5.6 L, if the temperature is increased to 400K.

Charles law is an ideal gas law which states that at a constant pressure volume of a gas is directly proportional to the absolute temperature.

It is expressed as

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

where,

V₁ = initial volume

T₁ = initial temperature

V₂ = final temperature

T₂ = final temperature

Now put the values in above formula, we get

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

[tex]\frac{3.5\ L}{250\ K} = \frac{V_2}{400\ K}[/tex]

[tex]V_{2} = \frac{3.5\ L \times 400\ K}{250\ K}[/tex]

[tex]V_{2} = \frac{1400}{250}[/tex]

V₂ = 5.6 L

Thus, from the above conclusion we can say that A 3.5L flexible container holds a gas at 250K. The new volume will be 5.6 L, if the temperature is increased to 400K.

Answer:

16 g.

Explanation:

The formula for carbon monoxide is CO.

So there is one atom of oxygen in the formula, therefore there is one mole of oxygen gas ( one mole occupies 22,4 L at STP)

One mole of oxygen atoms =  atomic mass of oxygen in grams = 16 grams.

Answer:

[tex]\boxed {\boxed {\sf A. \ Change \ in \ state \ of \ matter}}[/tex]

Explanation:

A physical change occurs when only the physical properties change. They are generally reversible and no new substances are formed.

However, in a chemical change, the chemical structures and properties change, plus new substances are formed.

Let's analyze each answer choice.

1. Change in state of matter

The state of matter is a physical property, so this is a physical change.

2. Precipitate was formed

A precipitate is a solid formed in a liquid solution. This is a new substance and a chemical change.

3. Unexpected change in odor.

A change in odor is a sign of chemical change.

4. Formation of bubbles

Bubbles signify the formation of gas or a new substance.

So, the best answer choice is A. change in state of matter

Question:

Which of the following would be the evidence of a physical change?

a. change in state of matter

b. precipitate was formed

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.

Answer:

Explanation:

Insulin is an hormone used to regulate blood glucose, as it helps to maintain a balance. It allows for transport of glucose to organs such as liver.

The process of glucose regulation is a complex process. When food is eating glucose is absorbed into the bloodstream this happen from the gut and it raises the blood glucose level this causes insulin(hormone) to be released from the pancreas so glucose can move inside the cells and be used.

As glucose moves inside the cells, the glucose level inside the bloodstream returns to normal and insulin release slows down.

Glucose which is the main energy source used by cells is allowed to be taken up by muscles, liver and fat (adipose tissue) and use as a source of energy so they can function properly.

Answer:

500 hits

Explanation:

If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?

Solution:

Given that:

20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz

10 webs = 1 futz; hence:

1 web = 1 web * 1 futz / 10 webs = 0.1 futz

1 web = 0.1 futz

1 futz = 2 geese; hence:

0.1 futz = 0.1 futz * 2 geese / 1 futz

0.1 futz = 0.2 geese

Therefore, 1 web = 0.1 futz = 0.2 geese

1 web = 0.2 geese

This means that 20 hits = 1 web = 0.2 geese

20 hits = 0.2 geese

5 geese = 5 geese * 20 hits / 0.2 geese

5 geese = 500 hits
