Answer:

Sulfur dioxide

Explanation:

Sulfur dioxide (SO₂) is a colorless gas, which comes from burning fossil fuels like burning coal, oil and diesel from vehicles. This gas is also released into the environment through volcanic eruptions.

Sulfur dioxide is considered one of the worst air pollutants, mainly because it accumulates in droplets in the air and also because it reacts with other compounds in the atmosphere, forming particulate materials.

This gas is a major contributor to the warming of the planet. Its presence in acid rain (which makes it return from the atmosphere to the earth) is dangerous for plants and animals, in addition to corroding some materials and affecting monuments, buildings, statues.

Acid rain generated by SO₂ and other compounds can lower the pH of lakes and reduce fish populations. In plants, vegetables and flowers, it compromises production and growth.

In humans, sulfur dioxide can cause acute and chronic health effects, especially on the respiratory system, in addition to aggravating cardiovascular problems due to the simultaneous presence of SO₂ and particles in the atmosphere.

Myth: A dead organism is the same as a nonliving thing in science.<br><br> Fact:<br><br> Evidence:
Ilya [14]

I recently did this assignment!

Instructions: Read each myth (untruth). Reword it to make a factual statement. Then, give two to three reasons why the myth is untrue. Use complete sentences and support your answer with evidence, using your own words.  

________________________________________

Answer:

Myth: A dead organism is the same as a nonliving thing in science.

o Fact: In science, dead is the same as nonliving.

o Evidence: Things that are nonliving never had the characteristics of life, and never will. Things that are dead once did have the characteristics of life, but when they die, they lose some of the characteristics. That is why dead and non-living are NOT the same thing.

Hope this helped!

Have an Amazing day!

Do atoms lend and borrow electrons from inner shells
zaharov [31]
False. They don't borrow electrons at all. They already have their respective electron affinities. This is called as electronegativity, and it's an occurence where it already has its own from its actual structure. It never borrows any electrons at all.

at do oxygen (O) and bromine (Br) have in common? They both tend to gain electrons to gain stability. They both have seven valen
avanturin [10]
Both of them have high electronegativity. Hence they both tend to gain electrons to gain stability.

What is the entropy change in the environment when 5.0 MJ of energy is transferred thermally from a reservoir at 1000 K to one a
Leni [432]

Answer:

The entropy change in the environment is 3.62x10²⁶.

Explanation:

The entropy change can be calculated using the following equation:

\Delta S = \frac{Q}{k_{B}}(\frac{1}{T_{f}} - \frac{1}{T_{i}})

Where:

Q: is the energy transferred = 5.0 MJ

k_{B}: is the Boltzmann constant = 1.38x10⁻²³ J/K  

T_{i}: is the initial temperature = 1000 K

T_{f}: is the final temperature = 500 K

Hence, the entropy change is:

\Delta S = \frac{5.0 \cdot 10^{6} J}{1.38 \cdot 10^{-23} J/K}(\frac{1}{500 K} - \frac{1}{1000 K}) = 3.62 \cdot 10^{26}                                    

Therefore, the entropy change in the environment is 3.62x10²⁶.

I hope it helps you!

based on the general trends on intermolecular forces, rank c2h5oh, hcl, and c3h6 in order of increasing boiling point.
nikklg [1K]
The answer is HCl, C3H6 and C2H5OH. Hydrochloric acid has the lowest boiling point among the three choices since it only has weak dipole-dipole and Van der Waal's forces between molecules which are much weaker than the forces of attraction present in propane and ethanol. Ethanol has the highest since the hydrogen bonding present in ethanol make it hard to break the bonds.
