an example for combustion reaction is as follows
combustion of methane;
CH₄ + 2O₂ --> CO₂ + 2H₂O
correct answer is
2. combustion
Answer:
[H+] = 1.74 x 10⁻⁵
Explanation:
By definition pH = -log [H+]
Therefore, given the pH, all we have to do is solve algebraically for [H+] :
[H+] = antilog ( -pH ) = 10^-4.76 = 1.74 x 10⁻⁵
