Answer:
Explanation:
Given:
pH = 4.7
But,
pH = -log[H3O+]
[H3O+] = 10^-pH
[H3O+] = 10^-4.7
= 1.995 × 10^-5
= 2 × 10^-5 M.
Answer:
1.995*10⁻⁵
Explanation:
pH = 4.7
[H₃O⁺] = ?
pH = -log[H₃O⁺]
4.7 = -log[H₃O⁺]
Take the anti-log of both sides,
[H₃O⁺] = 10⁻⁴·⁷
[H₃O⁺] = 1.995*10^-⁵

That is false. mass is converted into energy
2H2O➡2H2+O2 is the correct balanced equation of decomposition
Because decomposition means a molecule breaking down in to segments
