Answer:
NaBH4
H3O+
Explanation:
The conversion of 3-pentanone to form 3-pentanol is a reduction reaction. The first step of the reaction is the transfer of a hydride ion to the carbonyl from the reducing agent sodium borohydride.
After the transfer of the hydride ion, transfer of a proton from H3O+ completes the reaction mechanism hence 3-pentanol is formed from 3-pentanone.

Characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.
<h3>What is atomic theory?</h3>
Atomic theory is the scientific theory that matter is composed of particles called atoms.
The discoveries of subatomic particles such as;
- electron by J.J. Thomson
- proton by Ernest Rutherford
- neutron by James Chadwick
- nucleus by Ernest Rutherford
all contributed in the development of the atomic theory.
From the information given in the passage J.J. Thomson experiment gave rise to atomic model while Rutherford, Geiger and Ernest Marsden, performed the experiment that discovered nucleus and proton.
Thus, characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.

Heat will flow from the metal to the water until both are at a temperature somewhere between 20oC and 300oC.
Explanation:
The correct option is that heat will flow from the metal to the water until both are at a temperature somewhere between 200°C and 300°C.
At this point, thermal equilibrium is established in the mixture.
- Heat flows from a body at high temperature to the one with a low temperature.
- Heat will flow from the metal at 300°C to the water at 200°C.
- The heat flow will stop when both the water and aluminium block attains thermal equilibrium.
- This would logically be at a temperature between 200 to 300°C.
- The metal will lose heat and the water will gain heat until both are at a uniform temperature.
