Answer:

The correct would be C i think :)

Explanation:

Stay postivie :)

Answer:

2 and 3 is the answer because Methane is emitted from a variety of anthropogenic (human-influenced) and natural sources. Anthropogenic emission sources include landfills, oil and natural gas systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial processes

Answer:

when the sun's light hits a living thing

Answer:

helium

Explanation:

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Answer: 2nd answer " C "

Explanation:

First ionization energy is a periodic trend that increases up and to the right on the periodic table. After looking at the position of these elements on the periodic table, carbon is clearly the best answer-choice (B) aka " C "

Answer:

A - X Only

Explanation:

Answer: Chlorine (Cl)

Explanation:

[tex]\sf{\underline{ Chlorine\red{(Cl)}}}[/tex] is the elements has a mass of 35.5 amu. and the atomic number is 17

Answer:

Fertilization

Explanation:

Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.

Answer:

true

Explanation:

Answer:

1. mercury.

2. suspensions.

3.iodine is the solute and alcohol is the solvent.

4. A element.

The transition between n=1 and n=2 corresponds to the longest wavelength with the lowest frequency.

An electron is said to be "excited" when it is promoted to a higher energy level inside its bound state.

Either the electron absorbs a photon and obtains all of its energy, or it receives energy via a collision with another, energetic electron.

Understanding energy levels :

Therefore the transition between n=1 and n=2 corresponds to the longest wavelength at the lowest frequency.

The higher the frequency of a photon, the higher its energy.

The longer the wavelength of a photon, the lower its energy.

                                  E ∝ 1/λ      [ FOR PHOTON ]

The lowest energy is 1 eV, which corresponds to the transition between the n=1 and n=2 levels.

The longest wavelengths are associated with the lowest energies, so transitions between n=1 correspond to the longest wavelengths.

The term "thermal excitation" refers to the process by which electrons within a semiconductor crystal lattice are elevated to a higher energy band via lattice vibrations. This process, known as electron relaxation, occurs when an excited electron returns to a less energetic state.

As a result, a photon is released into the environment, or energy is transferred to another particle. The amount of energy released is proportional to the gap in potential energy between the electron's lowest and highest states.

Explanation:

I just took the test

Answer:

Next time you're just recently out of a serious relationship, and you're craving some sort of intimacy and comfort, feel confident that a rebound might actually be a good thing as long as it's an upgrade, either physically, emotionally, a fun date, or even just finding a way to shift your mentality toward viewing. so what im saying is if your happy in that relationship stay in it and if he or she becomes a meany leave it its not goo for your health

Answer:

The prediction of the student about the amount of reactant and product is incorrect.

No, I do not agree with the student’s prediction because the amount of reactant is always equals to the amount of product. According to the Law of Conservation of Mass, mass cannot be created nor destroyed. Therefore in any chemical reaction the mass of the products must equal or same to the mass of the reactants so according to this law, the prediction of the student is incorrect.

Explanation:Give brailiest please

Answer:

The chemical reaction that occurs when vinegar and baking soda (sodium bicarbonate) are combined, creates a gas that is known as carbon dioxide (or CO2). I would agree with the student's prediction because the atoms rearrange themselves to create the product.

Answer:

The substance (or substances) initially involved in a chemical reaction are called reactants or reagents.

Explanation:

Answer:

The chemical or substances used to start a reaction are called reactants.

Answer & Explanation:

For the water to H2 and O2 problem:

1) Reactant is H20, it is to the left of the arrow.

2) Products are H2 (gas) and O2 (gas) because it is to the right and what is created.

For the CO2 + water -> Glucose + Oxygen problem:

1) Reactant is CO2 and H2O, it is to the left of the arrow and what is being changed.

2) Products are C6H12O6 (glucose) and O2 (gas) because it is to the right and what is created.

Well I also need help with this, this should help the both of us:

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Explanation:

The first two period elements can form maximum 4 covalent bonds. However, third or higher period elements can make higher number of bonds for example; SF6.
