Which has the strongest conjugate base?
aleksandr82 [10.1K]

Answer:

Phenol.

Explanation:

Hello there!

In this case, for this question about the strength of the resulting conjugate base, it is possible for us to know that the higher the Ka (stronger aid) the weaker the conjugate base. In such a way, since the phenol has the smallest Ka (weakest acid) we infer that it has the strongest conjugate base.

In addition to the aforementioned, the reason why phenol was the answer is because the Kb of its conjugate base is the greatest due to the Kb=Kw/Ka and thus, the smaller the Ka the bigger Kb.

Regards!

tangare [24]

Answer:

When the hammer is in the sun, heat flows by radiation

When you pick up the hammer, heat flows by conduction

Explanation:

As the hammer lies in the sun, heat is transferred to the hammer by radiation. Heat energy reaches the earth from the sun by radiation. Radiation is a mode of beat transfer in which heat is transferred without a material medium.

When you pick up the hammer, heat flows to your hand by conduction because your body is a conductor of heat.
