This is a synthesis reaction or a combination reaction
The given reaction is C₅H₉O + O₂ → CO₂ + H₂O
On balancing the equation we get:
20 C₅H₉O + 90 O₂ → 100 CO₂ + 9 H₂O
This is a single replacement type of reaction. A single replacement reaction, also called a single-displacement reaction, refers to a kind of chemical reaction where an element reacts with a compound and occupies the place of another element in that compound.

Answer:
[OH-] = 0,071 mol/L
Explanation:
pOH = -log[OH-]
[OH-] = 10^-pOH = 10^-1.15 = 0,071 mol/L
