Answer:

Give up 2 electrons.

Explanation:

Is this ever a good question!!!

Electrons have a minus charge

Protons have a plus charge.

You need to understand it thoroughly.  I used to explain it this way.

Suppose the protons and electrons are playing a game and the electrons commit a foul that leaves them with 2 men short.

That means there are 2 unguarded plus's around. The result is that the minuses have lost two men who are in the sin bin. (I watch a lot of hockey).

So a +2 means that the electrons have lost two of their players to penalties.

Put in the vocabulary of your question, you give up 2 electrons.

Answer:

3.40x10¹⁰ grams

Explanation:

First we convert 5.25x10³² atoms to moles, using Avogadro's number:

5.25x10³² atoms ÷ 6.023x10²³ atoms/mol = 88.72x10⁸ mol

Then we convert K moles to grams, using its molar mass:

88.72x10⁸ mol * 39 g/mol = 3.40x10¹⁰ g

So 5.25x10³² atoms of K would weigh 3.40x10¹⁰ grams.

Answer:

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

Mg + HCl - > MgCl2 + H2

First, balance the equation.

There is only 1 H and 1 Cl at the left side. BUT there are 2 Cl and 2 H at the right side. So you can add a 2 in front of HCl to balance it.

Mg + 2HCl - > MgCl2 + H2

Formula 1: (n= m/mr)

n = moles, m= mass, mr = molecular mass

Formula 2: (n= v/24)

v = volume

Part 1

What mass of HCl is consumed by the reaction of 3.15 mol of magnesium?

Ratio of

(look at the number in front of each)

2HCl : Mg

2 : 1

(3.15 x 2) : 3.15 moles

6.3 moles : 3.15 moles

So 2HCl has 6. 3 moles

Now use formula 1 (n = m/mr)

Calculate molecular mass of HCl

Check your periodic table

mr of HCl =(1 + 35.5) = 36.5

6.3 = m/36.5

m = 229. 95grams

Part 2

What mass of MgCl2 is produced? Answer in units of g.

Ratio of

2HCl : MgCl2

(1 +35.5) : (24+35.5x2)

36.5: 95

229.95g :?

229.95g : 598.5g

m = 598.5g

Part 3

What mass of H2 is produced? Answer in units of g.

2HCl : H2

36.5 : 2

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.

[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:

There are some climates in which there are no living things. The average of the weather is the 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.
