Answer:
1)D)Fission is the process when the nucleus of an atom splits after being bombarded by neutrinos.
2)A)Storage and disposal of radioactive waste is a problem all nuclear power plants face. Most of them dipose the waste underneath the ground. There have even been proposals to send the nuclear waste to the moon.
3)C)Nuclear Power because it does not produce greenhouse gas emissions.
4)A) Oil is more difficult to remove from the Earth than coal This is why, to extract oil, you need an extraction pump and other equipment, while coal can be removed from the earth after digging.
5)A) biofuel - because it comes from agriculture, and agriculture is the biggest contributor to worldwide greenhouse emissions.
6)B) Geothermal power - geothermal power uses the heat from the earth to produce energy.
7)D) - Humans have seemingly unlimited needs and these needs have to be met without destroying the enviroment.
8)C) Xenon - The other three substances listed are classified as Ozone depleting susbstances according to the Ministry of the Enviroment in New Zealand.
9)B) Synthetic materials often do not decay naturally - The best example is plastic, which is a synthetic material that takes hundreds or even thousands of years to decay.
10)C) An environmentally safe base to neutralize the lake - This can be done by oxygenizing the lake.
11)D) Oil spills - Unfortunely, these events have taken place many times. The oil spill in the Gulf of Mexico caused by British Petroleum greatly affected the coasts and waters of Louisiana.
12)D)The whole ecosystem is negatively affected, and long-term damage may occur - An oil spills afects aquatic plants, animals, birds, and the water itself.
13)B)Natural resources will be depleted - Oil might even run out completely. Besides, climate change would raise the sea levels and flood thousands of cities.
14)D) factories and power plants - especially thermal power plants that burn coal to produce energies.
Answer:
D, ABC, C, A, ?, B, A, ?, B, C, D, D, C, D
Explanation:
(Answers and explanations in order of questions)
Fission reactions are when the nucleus of an atom splits producing smaller nuclei and energy
Lack of space isn't a safety risk
Coal, natural gases, and oil all are burned to create energy which releases carbon into the atmosphere, polluting it. Nuclear power doesn't burn carbon-based substances and so is fine
I dunno but C and D are wrong
All of them are technically renewable?
Geothermal energy uses the Earth's heat, hence the name
Nothing can happen if people ignore it
Unsure
Synthetic polymers are plastics, which do not decay naturally
A base would react with the acid to neutralise it which is the fastest way to improve the lake
Not pesticides?
Oil spills kill aquatic animals and life quickly, which causes huge damage to ecosystems
If nothing changes nonrenewable things will run out and bad practices will have caused irreparable damage worldwide
Big factories are pumping out the bad stuff

The definition of solubility is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature or pressure (in the case of gaseous solutes). For Gases, solubility decreases as temperature increases (duh...you have seen water boil, right?) The physical reason for this is that when most gases dissolve in solution, the process is exothermic. This means that heat is released as the gas dissolves. This is very similar to the reason that vapor pressure increases with temperature. Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution. Do you need any more?
Valence electrons are the electrons that reside in an atom's outermost shell. The role of valence electrons in determining an atom's reaction makes them crucial. You can count how many electrons are at the highest energy level by writing an electron configuration.
How do the valence electrons function?
The electrons in an atom's outermost shell are called valence electrons. … Because the electrons in the outermost shells of two atoms are the first to come into contact with one another and are the ones that control how an atom will react in a chemical reaction, when two atoms interact.
The outer-shell electrons of an atom are known as valence electrons. The valence electrons in an atom control its reactivity.

Answer:
35.00 mL
Explanation:
42,256 = 2,000
42,256 = 200
together they'd be 2,200 (if that's what you needed as well)
Answer:
The bonding angle, the kind of bonds, the size of the molecule, and the interactions between molecules are all part of the chemical structure. Slight alterations in the chemical structure can have a significant impact on the compound's characteristics.
