Oxygen (O2) and nitrogen (N2) do not have much greenhouse effect, but several trace gases including carbon dioxide (CO2), methan

AleksandrR [38]

<h3><u>Full Question:</u></h3>

Oxygen ( $O_2$ ) and nitrogen ( $N_2$ ) do not have much greenhouse effect, but several trace gases including carbon dioxide ( $CO_2$ ), methane ( $CH_4$ ), nitrous oxide ( $N_2O$ ), and various chlorofluorocarbons are important greenhouse gases. The primary mechanism by which these greenhouse gases warm the Earth is:

A. Making politicians mad, so they give speeches that heat the air.

B. Experiencing chemical reactions with each other, which release energy.

C. Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer.

D. Raising the atmospheric pressure, because squeezing air warms it, as we saw at the Redwoods.

E. Absorbing some of the infrared radiation emitted from the Earth.

<h3><u>Answer:</u></h3>

The primary mechanism by which these greenhouse gases warm the Earth is absorbing some of the infrared radiation emitted from the Earth.

Option E

<h3><u>Explanation:</u></h3>

Though the pressure does not set the temperature, but the changes in pressure brings changes in temperature. The rare greenhouse gases does not affect the pressure much. The imbalance in greenhouse gases are very less when compared to the effects of radioactive gases. Greenhouse glass blocks the convection currents which is not blocked by greenhouse gases. The infrared radiation emitted from the planet is adsorbed by $CO_2$ .

The $CO_2$ move into excited state by the infrared photon absorption which quickly returns to the normal state by emission of photon with same energy. These photons emitted from this excitation comes towards Earth which helps in trapping the energy of warming the planet which achieves new balance.

Which of the following bond types is the strongest?

Andre45 [30]

Answer:

b) Ion-dipole

Explanation:

Intermolecular forces are the forces of attraction or repulsion between molecules, they are significantly weaker than intramolecular forces like covalent or ionic bonds.

<em>Hydrogen bonds</em> happen between a partially positively charged hydrogen and another partially negatively charged, it's a type of dipole-dipole interaction, one of the strongest among intermolecular forces.

<em>Ion-dipole</em> involves an ion and polar molecule, its strength is proportional to the charge of the ion. It's stronger than hydrogen bonds because the ion and the polar molecule align so positive and negative charges are next to another allowing maximum attraction.

<em>Dipole-dipole </em>is an interaction between two molecules that have permanent dipoles, aligning to increase attraction.

<em>Ion-dipole</em> induced usually happens when a non-polar molecule interacts with an ion causing the molecule to be temporary partially charged. It's a weaker interaction.

<em>Dipole- Induced Dipole</em>, like ion-dipole induced this interaction causes one of the two involved molecules to be temporary partially charged.

Considering this information we can conclude that Ion-Dipole interaction is the strongest force among intermolecular forces.

I hope this information is useful to you!

Do bases contain hydrogen ions (H+)

Dmitrij [34]

One definition of an acid is a molecule that can donate a H+ ion. So for example if you have an acid such as hydrochloric acid (HCl) in water, HCl will donate it's H+ to the H2O molecule, forming Cl- and H3O+.

In contrast, a base is a molecule that accepts H+ ions. This means a base such as NH3 reacts with H2O to form OH- and NH4.

So when pH is measured, it is the ratio of H3O+ ions to OH- ions. If there are more H3O+ ions, you then know that there are more acidic molecules in the solution, since they must be giving away their H+ ions.

So a solution with an acid in it will have more H3O+ ions (which can be described as H+ ions) in it. However, an acid by itself will have nothing to donate H+ ions to.

hope this helps also please make me the brainliest

A

meriva

Answer:

Option B is correct. A nuclear alpha decay

Explanation:

Step 1

This equation is a nuclear reaction. So it can be an alpha decay or a beta decay

An α-particle is a helium nucleus. It contains 2 protons and 2 neutrons, for a mass number of 4.

During α-decay, an atomic nucleus emits an alpha particle. It transforms (or decays) into an atom with an atomic number 2 less and a mass number 4 less.

Thus, radium-226 decays through α-particle emission to form radon-222 according to the equation that is showed.

A Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.

Option B is correct. A nuclear alpha decay

Answer in detail?? What precautions would you take to protect yourself from an earthquake, when you are at home and when you are

Dmitry [639]

Answer:

If you're indoors, stay inside. If you're outside, stay outside. If you're indoors, stand against a wall near the center of the building, stand in a doorway, or crawl under heavy furniture (a desk or table). Stay away from windows and outside doors.
