MULTIPLE CHOICE QUESTION

Electrons fill in energy levels in which of the
following ways?

1.Lowest energy level first, so it fills in the inside
rings first

2.Lowest energy level first, so it fills in the
outside rings first

3.Highest energy level first, so it fills in the inside
rings first

4.Highest energy level first, so it fills in the outside
rings first

Answers

Answer 1

Answer:

I think the answer is 3. Highest energy level first, so it fills in the inside rings first

Answer 2

Electrons occupy the lower-energy orbitals first, then go on to fill the next higher-energy orbital until all of the electrons contain been placed.

Which energy levels do electrons fill first?

Most of the time, electrons occupy the lower-energy orbitals first, then go on to fill the next higher-energy orbital until all of the electrons have been positioned.

The lowest energy level is always added to initially until it has as many electrons as it can have. The following higher energy level is then filled with electrons, and so on.

The lowest energy level is always filled up with additional electrons first, up to the point where that level can hold no more, and then further electrons are added to the next higher energy level, and so on. A level's total number of orbitals determines how many electrons can be present at that energy.

Therefore, the correct answer is option 3. Highest energy level first, so it fills in the inside rings first.

The question at the beginning of todays reading is , In what ways do people use detectors why is it important to understand particles in order to invent detectors

Answers

Answer:

Explanation:

People use detector to know the ionization of electromagnetic radiation i.e alpha, beta and gamma radiation and the output produced.

In the past, the early detectors use photographic plates which is use to detect tracks due to nuclear reactions.

It is important to know particles before inventing detectors because detectors produces visible trajectories or tracks as a result of particles that are charged which can traverse the apparatus. It was used to detect the positron and also muons and these w are particles that are produced by cosmic rays which is as a result of their interaction in the Earth's atmosphere.

Does sound travel faster in a warm room or a cold room?
Explain your answer.
2 paragraphs answer ASAPP

Answers

Answer:

Sound is vibrations that travel through a medium, and which are then converted into electrical signals by our brain so that we interpret them as a noise that we hear. These vibrations consist of particles colliding with each other (this is why sound cannot travel through space; there are no particles). At warmer temperatures, the particles that make up air will move faster, so these collisions will happen more frequently. Therefore the vibrations occur more quickly, so sound travels faster and reaches our ears in a shorter amount of time.

The speed of sound can travel faster in hot air than it can in cold air. This is because the molecules of air can move even faster and the vibrations of the sound wave can transmit faster. Sound is a type of mechanical wave, meaning that it requires a medium to transmit energy. Mediums are any substance that has mass and takes up space, from the air in the room to the metal atoms in an iron fence.

Explanation:

hope that helps :)

Answer:

Sound travels faster in a warm room because temperature affects the speed of a wave. In a warm room, the particles of air move faster and have higher chances of bumping into each other, which then increases the instances of energy transfer.

How many grams are in 2.3 moles of O?

Answers

Answer:

36.8 g/mol of O

Explanation:

To find the number of grams, multiply the number of moles by the atomic mass of the element.

Oxygen has an atomic mass of 16.00.

2.3 moles O × (16.00 g O ÷ 1 mole) = 36.8 g/mol O

what is a unique characteristic of covalent bonding between nonmetal atoms
a) atoms give away electrons to reach a stable octet
b)atoms share valence electrons with neighboring atoms to reach a stable octect.
c)atoms gain electrons to reach a stable octet
d)delocalized electrons move freely among many positive atoms creating a ''sea'' of electrons

Answers

Answer:

The answer isssssssssssssss DRUM ROLL PLEASEEE

Explanation:

B

Considering the definition of covalent bonds,  the correct answer is option b): atoms share valence electrons with neighboring atoms to reach a stable octect.

Covalent bonds are the forces that hold non-metallic atoms together. These atoms have many electrons at their outermost level (valence electrons) and have a tendency to gain electrons rather than give them up, to acquire the stability of the noble gas electronic structure. Therefore, non-metallic atoms cannot give electrons to each other to form ions.

In other words, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule. Atoms share pairs of electrons from their most superficial shell (called the valence shell) to achieve the stability of the molecule that has been formed with the bond and thus comply with the octet rule.

In summary, the correct answer is option b): atoms share valence electrons with neighboring atoms to reach a stable octect.

A student measures 10 g of baking soda and mixes it with 5 grams of vinegar. The mixture begins to bubble and fizz and feels cold to the touch. Once the reaction is over the student weighs the solution and discovers that the resulting mixture weighs only 12g. What happened to the missing 3 grams of product? Use the Law of Conservation of Matter in your answer.

Answers

Answer:

Some of the product is a gas that goes to the atmosphere.

Explanation:

Based on the chemical reaction of baking soda (Sodium bicarbonate: NaHCO₃) with vinegar (Acetic acid: CH₃COOH):

NaHCO₃(aq) + CH₃COOH(aq) → H₂O(aq) +  CO₂(g) + CH₃COONa(aq)

When the reaction occurs, one of the products (CO₂) is a gas that will disappear of the mixture to stay in the atmosphere. That is the reason why there are missing 3 grams.

Which event may occur when ocean salinity increases?

mass of water increases
freezing point of water increases
sunlight in deeper locations decreases
amount of dissolved gases in water increases

Answers

Answer:

The answer is C: “sunlight in deeper locations decreases”

Explanation:

The answer is C because the more salinity water has.. the harder it is to see and the harder it is for light to travel through the ocean.

Based on the given options, when ocean salinity increases, the amount of sunlight in deeper locations decreases due to increased turbidity.

What is ocean salinity?

Ocean salinity refers to the amount of dissolved salts present in ocean water.

The salinity of the ocean increases in events such as volcanic eruptions due to the influx of minerals into the ocean.

When ocean salinity increases:

the amount of dissolved gases decreases the freezing point of water decreases the amount of sunlight in deeper locations decreases due to increased turbidity

Therefore, when ocean salinity increases, the amount of sunlight in deeper locations decreases due to increased turbidity.

The diagram represents the path of a ball that has been thrown upward.

Ignore friction between the ball and the air. (3 points)

Answers

Answer:

Gravitational potential energy: [tex]GPE_{B}>GPE_{A}>GPE_{C}[/tex]

Kinetic energy: [tex]KE_{B}<KE_{A}<KE_{C}[/tex]

Total mechanical energy: [tex]ME_{A}=ME_{B}=ME_{C}[/tex]

Explanation:

The gravitational potential energy is directly proportional to height ([tex]GPE_{B}>GPE_{A}>GPE_{C}[/tex]). Since there are no non-conservative forces, the total mechanical energy is conserved ([tex]ME_{A}=ME_{B}=ME_{C}[/tex]) and the total mechanical energy is the sum of gravitational potential and kinetic energies. Then:

[tex]GPE_{A} + KE_{A} = GPE_{B} + KE_{B} = GPE_{C} + KE_{C}[/tex] (1)

If we know that [tex]GPE_{B}>GPE_{A}>GPE_{C}[/tex], then we conclude the following inequation for the kinetic energy:

[tex]KE_{B}<KE_{A}<KE_{C}[/tex] (2)
