Answer:
2.853881279 years
Explanation:
I multiplied 365 times 24 to get 8760 hours in a year. I then multiplied this by 60 to get 525600 seconds per year. Lastly, I divided 1500000 by 525600 in order to get the answer. Hope this helps!
Temperature means, in this context, movement.
Condensation can be explained by the reduction of temperature of the system. This effect make possible the cohesion forces increases. In other words, the result is coalescence by attractive forces.
a) Mg is oxidized and O2 is reduced
b) Zn is oxidized while Pb(NO3)2 is reduced.
<h3>Oxidation and reduction</h3>
Oxidation is defined as:
- loss of electrons
- removal of hydrogen
- addition of oxygen
- increase in oxidation number
- removal of electropositive elements
Reduction is defined as:
- gains of electrons
- addition of hydrogen
- removal of oxygen
- decrease in oxidation number
- addition of electropositive elements
Looking at the first reaction, the Mg atom gains oxygen to become MgO. This means that Mg is oxidized. The oxidizing agent is O2. At the same time, O2 is being reduced and the reducing agent is Mg.
For the second reaction, the oxidation number of Pb is reduced from +2 to 0. Thus, Pb has been reduced by Zn while Zn itself has been oxidized. The reducing agent here is Zn while the oxidizing agent is Pb(NO3)2.
