Answer:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
- Combustion Reactions: CₓHₙ + O₂ → CO₂ + H₂O
Explanation:
<u>Step 1: Define</u>
RxN A: C + O₂ → CO₂
RxN B: CO₂ + 4H₂ → CH₄ + 2H₂O
RxN C: 2N₂O₅ → 4NO₂ + O₂
RxN D: 2NO + O₂ → 2NO₂
RxN E: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
<u>Step 2: Identify</u>
RxN A: Synthesis Reaction
RxN B: Half of an Equilibrium equation for Combustion
RxN C: Decomposition Reaction
RxN D: Synthesis Reaction
RxN E: Combustion Reaction
Only reaction that is a combustion reaction is RxN E. Every other RxN is not a combustion reaction.
Answer:
1.16 as a ratio and 1.1 as difference.
Explanation:
Hello there!
In this case, since the pH stands for the relative strength of the hydrogen ions in a solution, it is widely known that the pH of the ocean is about 8.1 due to the dissolved HCO3^- ions dissolved in it. On the other hand the pH of pure water is known as 7.0 as the only neutral solution.
Thus, by dividing the pH of the ocean by the pH of the pure water, we can calculate the units or ratio between them:
Or also the difference separating them:
