Answer:
Molecules in both the metal and the surrounding air will start moving at higher speeds.
Explanation:
Temperature is a measure of the average kinetic energy of the molecules in a body. Thus, as the temperature of a body increases, its molecules tend to move faster.
At a high temperature of 150°C, the molecules in the metal hot plate move faster. Similarly, this heat is also transferred to the surrounding air molecules and they too start moving faster.
Therefore at 150°C, molecules in both the metal and the surrounding air will start moving at higher speeds.
Answer:
Explanation:
-log(3.5 * 10^-11)
= 10.4559
Be careful how you put this into your calculator. I had to use Exp to get it to work properly.
-log
(3.5 * 10 exp -11)
=
Answer:
Oxygen is oxidizing gent and itself get reduced while lead is reducing agent and itself get oxidize.
Explanation:
Chemical equation with oxidation state:
O⁰₂(s) + Pb⁰ (s) → Pb⁺⁴O₂⁻²(s)
Oxidizing agent:
Oxidizing agents, oxidize the other substance and itself get reduced. They can be identify by just looking the oxidation state. If oxidation state is decreased on the right side it means substance gain the electron and get reduced.
Reducing agent:
Reducing agents, reduce the other substance and itself get oxidize. They can be identify by just looking the oxidation state. If oxidation state is increased on the right side it means substance lose the electron and oxidation state increased.
In given chemical equation, oxygen and lead were in neutral form they react and form lead dioxide. In this product oxygen is oxidizing gent and itself get reduced and oxidation state change from 0 to -2 while lead is reducing agent, itself get oxidize and oxidation state change from o to +4.
