ANSWER

The number of protons in an atom of N-15 is 7



<u>STEP-BY-STEP EXPLANATION:</u>



Firstly, we need to define an isotope

Isotopes are two or more atoms that have the same atomic number and position in the periodic table but different mass numbers due to differences in the number of neutrons.



Recall that, atomic number = no of proton

Since the isotopes of nitrogen are N-14 and N-15

The atomic number of nitrogen is 7 according to its position in the periodic table



Hence, the number of protons in an atom of N-15 is 7

Answer:

MAIN IDEA
What the authors meant is not to judge people by their looks.


_____________________________________________________________

THE UGLY DUCKLING

The ugly duckling doesn't fit with the other ducklings and grows up, to be a fabulous bird. In the beginning, he is teased because of his looks, in a quote, "As the ugly duckling grew, many animals in the pond criticized him. His feathers were too dark, his neck was too long, and his body was too big. His fellow ducklings refused to recognize that underneath the feathers, the ugly duckling was kind, good, and gentle. The ugly duckling shed many tears because none of the other animals would play with him."

Near the end, however, it states, "He believed that the swans would never be his friends and looked down into the pond in despair. Then, his eyes opened wide, for he saw his reflection. To his great astonishment, the ugly duckling discovered that he was a beautiful, royal swan! The swans welcomed their new friend, whose lovely appearance was matched only by his kind heart. He now felt like he belonged." Throughout the course of the story, the other birds' views change since now they realize how awful they felt for mistreating the ugly duckling.

THE PRINCESS AND THE PEA

The king and queen didn't believe that she was a princess, so they had her endure the trial of sleeping on twenty mattresses with a pea under the very bottom one. Near the beginning of the story, it states, "The disheveled maiden looked at the king in disbelief. "I am a princess, come to see the prince," she explained, all the while shivering. The king summoned his wife, the queen, for advice. The queen looked at the hideous creature in disbelief, thinking that no princess would ever allow herself to be found in such a state. She thought quickly and came up with a clever plan. The queen put a small pea at the bottom of a bed and piled twenty mattresses on top of it. When the girl arrived at the room, she had to climb a ladder to reach the top of the bed, where she collapsed in exhaustion." This is when the king and queen were in doubt that she was a princess.

However later on it stated, "Bright and early the next morning, the king and queen arrived at the girl's bed-chamber. The queen asked the girl how she had slept the night before. "Absolutely terribly!" bemoaned the maiden. "I have spent the entire night tossing and turning. I don't know whether there is something hard in the bed, or your mattresses are rocks, but my body is black and blue." The queen and the king stared at the maiden in astonishment. Only a real princess would have such delicate skin that she could feel a pea under twenty mattresses. The queen and king brought her to the prince, who was thrilled to meet a real princess with such an independent spirit." As you can see the king and queen believed that she was a princess now because they stated, "Only a real princess would have such delicate skin that she could feel a pea under twenty mattresses."

_____________________________________________________________

CONCLUSION
Both stories focus on how the main character is doubted or mistreated because of how they look, but throughout the stories, the main character proves them wrong.

Draw the Lewis structure (including all lone pair electrons) for one isomer of the molecular formula C3H8O.
Andreyy89

Answer:

Here's how I would do it.

Explanation:

A Lewis structure shows the valence electrons surrounding the atoms.

1. Identify the central atoms

The central atoms are the least electronegative atoms (C).

I chose as my central atoms a chain of four C atoms: C-C-C-C

I stuck the most electronegative atom (O) at the end of the chain:

C-C-C-C-O

2. Complete the structure

The hydrogen atoms must be terminal. Add enough to give every atom an octet.

You should get a structure like the one below

What happens when chlorine forms an ion?
zmey [24]

The chlorine usually forms a Chloride ion.

The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

What do you mean by Chlorine forming an ion?

Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.

The chloride ion is the anion  Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.

What are the roles of fungi? Check all that apply.
dmitriy555 [2]

Answer:

Fungi are a food source for animals and humans. This point do not apply on fungi.

Explanation:

Roles of fungi:

Penicillin and Cephalosporins are the antibiotics made by fungi. They are natural sources of antibiotics.

Fungi are eaten by animals  examples are mushroom, agaricus and some animals even eat poisonous mushrooms.

Fungi destroy by releasing chemicals into the rock and they get iron this way and then deeply burrow the rocks and harming them.

Fungi acts as a decomposer to nourish the soil and improves vegetation.

Many infections are caused by fungus like ringworm infection, candida and Athlete's food are some examples.
