Gasoline, and related fuels have helped society by being a reliable fuel which has powered great things. However these fuels pose hazardous chemicals that can be released into the environment, damaging our valuable ecosystem. Such as greenhouse gasses. However society can overcome these challenges by using other renewable resources. Like power from rivers and wind. In conclusion, great resources have great trade offs.

What ion do acids release in solution?
wariber [46]

Answer: H^+

Explanation: All the Arrhenius and Bronsted Lowry acids release H^+ ions in solution.

According to Arrhenius and Lowry, acids are substances which release  H^+ ions when dissolved in water.

Thus HCl, H_2SO_4 and H_3PO_4 all are considered as acids,

HCl\rightarrow H^++Cl^-

H_2SO_$\rightarrow H^++SO_4^{2-}

H_3PO_4\rightarrow H^++PO_4^{3-}

Which type of nuclear decay is the radioactive isotope fe2659 likely to undergo?
jekas [21]

Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.

Fe_{26} ^{59} → Co_{27} ^{59} +\beta_{1}  ^{0}

It can be seen that after the beta minus decay Fe changes into Co.

In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.

Neutron-rich nuclei often decay by producing both an electron and an antineutrino.

Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Which of these lists bodies in order, from CLOSEST to FURTHEST from the Earth? A) moon, sun, near edge of milky way, center of m
marta [7]
A) would be correct.

The moon is right next to Earth.

Earth orbits around the sun.

Our solar system is at the edge of the Milky Way. So the edge of the Milky Way would be nearer than the center.

Which one of the following is an oxidation-reduction reaction?
kupik [55]

Answer:

CH4 + 2 O2 --> CO2 + 2 H2O

Explanation:

CH4 + 2 O2 --> CO2 + 2 H2O is the only reaction where an element (oxygen) undergoes a change in oxidation state. In this reaction oxygen changes disproportionately to O⁻². That is ...

O₂ → CO₂ + 4e⁻ ==> oxidation

<u>O₂ + 4e⁻  →  H₂O ==> reduction </u>

2O₂ + 4e⁻  →  CO₂ + H₂O + 4e⁻  ==> Net oxidation-reduction

=>  4e⁻ gained by one mole O₂ in formation of CO₂ = 4e⁻ lost by the other mole O₂ in forming H₂O.

Then...

Including CH₄ (whose elements do not undergo changes in oxidation states) requires doubling reaction to balance by mass thus giving ...

2CH₄ + 2O₂ + 8e⁻  →  2CO₂ + 2H₂O + 8e⁻

Cancelling 8 reduction electrons on left with 8 oxidation electrons on right gives...

2CH₄ + 2O₂  →  2CO₂ + 2H₂O
