What constitutes a solar system?

Answers

The Solar System may be divided by its components into three major regions: the inner system, the near outer system, and the far outer system. The near outer system might also be referred to as the middle system.

Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.

Why does an ionic bond transfer electrons instead of sharing?

Answers

The modern definition of electronegativity is due to Linus Pauling. It is the power of an atom in a molecule to attract electrons to itself.

When the electronegativity difference between the two atoms is greater than 2.0, the bond is considered ionic; i.e. there is complete transfer (between the two atoms) of the electrons in the bond. The electronegativity (according to Pauling scale) of chlorine is 3.0, while the electronegativity of sodium is 0.9.

So, electrons are transferred because of a larger electronegativity difference.

When there is a whole transfer of valence electron between the atoms is called an ionic bond. In this type of bond construction, the atoms get contrarily charged.

The ionic bonds are formed due to electronegativity. According to Pauling, the capability of an atom to draw electrons towards itself is called electronegativity.

When there is a huge contrast in electronegativity between the atoms, the electrons are completely transferred between the atoms.

The atom that relinquishes an electron are called a cation and is positive whereas the atom that acquires an electron are called anions and are negatively charged.

Therefore, due to electronegativity, ionic bonds are formed.

2 The polar structure of water allows it to act as a solvent for many substances. Which of the
following statements best explains why water is considered polar?
F The unequal sharing of electrons results in the water molecule having a slightly negative
charge near its oxygen atoms and a slightly positive charge near its hydrogen atom.
G The equal sharing of electrons by the hydrogen and oxygen atoms form weak bonds that are
easily broken during dissociation.
H The unequal sharing of electrons results in the water molecule having a slightly positive
charge near its oxygen atoms and a slightly negative charge near its hydrogen atom.
The equal sharing of electrons by the hydrogen and oxygen atoms create a molecule that is
neutrally charged.

Answers

The answer would be F as oxygen is delta negative and hydrogen is slightly delta positive. Forming a permanent dipole.

Carbon dioxide

Explanation:

Hydrogen bonding takes place between hydrogen and either nitrogen, oxygen, or fluorine. Carbon has an electronegativity similar to hydrogen's, and will not hydrogen bond with hydrogens in other molecules. Only molecules with -OH, -FH, or -NH groups can form hydrogen bonds.

How would adding the catalyst nitrogen monoxide (NO) affect this reaction?

2SO2(g) + O2(g) → 2SO3(g)

A) NO increases the rate at which SO3 molecules are formed.

B) NO reacts with SO3 to produce more SO2 molecules.

C) NO decreases collisions between the SO2 and O2 molecules.

D) NO increases the concentration of the SO2 and O2 molecules.

E) NO increases the activation energy of the SO2 and O2 molecules.

Answers

Answer: A) NO increases the rate at which [tex]SO_3[/tex] molecules are formed.

Explanation:

A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more reactant molecules can cross the energy barrier by undergoing collisions and convert to products.

[tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]

Thus NO will increase the rate of reaction by lowering the activation energy and thus the colllisions among [tex]SO_2[/tex] and [tex]O_2[/tex] molecules will incraese which in turn will lead to formatioon of more [tex]SO_3[/tex] molecules.

Answer:

A) NO increases the rate at which molecules are formed.

According to the law of universal gravitation, gravity is the force keeping objects in the universe in their relative positions.truefalse The Mystery of Loch NessBy Kayden MitchellOf all the mysteries in the world, none has been as popular as that of the Loch Ness Monster. Perhaps the biggest mystery is whether it is convincing evidence or a simple desire to believe that keeps the myth alive.Loch Ness is a lake in Scotland. The loch, or lake, is known for sightings of a mysterious monster. Most who see this monster, known as Nessie, describe something with a long neck and several humps above the water. Sometimes the "monster" is moving in these sightings, and sometimes it is still. Many have suggested that Nessie might be a plesiosaur (plea-see-a-soar), an aquatic dinosaur that was trapped in the loch after the last ice age.The plesiosaur theory presents several problems. First, the plesiosaur is an air breather. Such a creature would need to surface often and, therefore, be seen more frequently. Second, it's unlikely that the same creature has lived in the loch since the last ice age. Today's creature would have to be the offspring of an original plesiosaur trapped long ago. This would suggest multiple creatures in the loch (needed to produce offspring). Again, sightings would be more frequent if this were the case.So from a purely logical stand point, the existence of such a large and ancient creature is unlikely. But assume for a minute that it is possible. What would a plesiosaur need to live in an enclosed lake?Tropical waters: Scientists believe plesiosaurs were warm-blooded. Like crocodiles and alligators, plesiosaurs would need to live in warm waters. The loch is very cold with temperatures averaging about 40 degrees Fahrenheit (4.4 Celsius).Food: Like other warm-blooded creatures, plesiosaurs would need a large quantity of food. If there is a group of Nessies, then even more food would be needed. Because the loch is full of silt (underwater dust) not much light gets into the deepest areas. So the food chain, which would depend on plankton, is very weak at its base. As a result, there is probably not enough food to support such a large creature.However, the plesiosaur theory is not the only one. Many other ideas attempt to explain the sightings and "photographs." But two separate sonar surveys of the loch have not found any evidence of a creature larger than a salmon. The last survey1, completed in 2007 by the British Broadcasting Company (BBC), involved 600 different sonar beams. Using satellite navigation systems, the team made sure every inch of the loch was searched. The team found nothing.With cell phones and digital cameras, one would think that sightings of Nessie would increase. This has not happened. The BBC team believes the legend of Nessie has endured because people see what they want to see. To prove this, the team used a fence post, raising it before groups of tourists. Afterwards several of the tourists asked to draw pictures of what they had seen drew pictures of a monster's head.Which best summarizes the results of sonar surveys? The simple tools cannot search at depths where the creature lives. The satellite navigation could not map the entire lake bottom. There are too many large salmon in the loch to find much else. They have found no evidence of anything bigger than a salmon.Question 2(Multiple Choice Worth 5 points) How did local South Carolinians attempt to assist Major General Horatio Gates andhis soldiers during the Battle of Camden?Locals joined the soldiers in battle, but their numbers could not withstand theBritish force.Locals suggested that Gates surrender to the British to avoid a battle he couldnot win.Locals suggested that Gates lead a surprise attack on the forested area wheremany Loyalists lived.Locals advised Gates to lead his army through rich farmland where Patriotsupport was high How many times larger is 4.5 x 105 than 1.8 x 10%?A. 2.5B. 270C. 250D. 50 Explain the importance of Nathaniel Bacons Rebellion.15 points btw ;) which of the following is a step in the marketing process Can someone please make up a short story for me, the short story can be about anything.
