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
Answer:s: It is durable, low cost, water resistant, lesser energy and heavy chemicals requirements in manufacture and are light weight
Explanation:
Answer:
Becuase they can go through mountains and hills, they curve of of those.
150,000 grams. Multiply 100 by 50 by 30 to find the volume of the container, which is 150,000 cm^3. knowing that a milliliter is just one cubic centimeter, and that water is one gram per milliliter, you can conclude that it is 150,000 grams of water.
A positive solid sphere with electrons dispersed.
