Q+ ( poistive ion ) is an ion of element Q.
What has the highest value in the ion?
The proton number has the highest value in the ion
In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.
Recall that:
The electron is usually negatively charged;The neutron is a neutralThe proton is usually positively charged.∴
The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.

Limonene is an oil from oranges and lemons. Click on all the carbon
atoms its structures that have a trigonal planar molecular geometry.
Answer:
See explanation
Explanation:
Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.
There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.
Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

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.
A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical
plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?
Answer:
Explanation:
The responding variable always is measured against the variable that you have control over.
In this case, you have control over the volume of air.
The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.
a. Identify the type of reaction shown:
Li + CaCl2 ---> LiCl + Ca
Answer:
single-replacement reactions
Explanation:
A single-replacement reaction is defined as a chemical reaction in which one strong element replace the other weak element.
The given chemical equation Li + CaCl2 ---> LiCl + Ca is an example of single-replacement reactions in which Lithium (Li) is stronger than Calcium (Ca) and replaces calcium to form bond with Chloride.
Hence, the correct answer is "single-replacement reactions".

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.

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