Explanation:
Radioactive isotopes are unstable isotopes whose neutron/proton ratio differs from its stability ratio.
- These isotopes will naturally decay and break down on their own.
- A nucleus with neutron/proton ratio combination which is different different from its stability ratio will be unstable and split into one or more other nuclei.
- This is accompanied by the emission of small energetic particles.

Answer:
d. diethyl alcohol
Explanation:
When ketones undergo reduction, they produce 2° alcohol, and 3-pentanone will produce dimethl alcohol as the secondary (2°) alcohol
Answer:
Combustion
Explanation:
Combustion reactions are the one where the oxygen is a reactant and the products are always water and carbon dioxide.
It is also a redox type because the oxygen is reduced and the carbon from the C₄H₁₀O oxidized to CO₂
C₄H₁₀O + 6O₂ → 4CO₂ + 5H₂O
1 mol of butyl alcohol burns in prescence of 6 moles of oxygen in order to produce 4 moles of carbon dioxide and 5 moles of water.
