Answer:
The current temperature is -15° (15° below zero)
Explanation:
The temperature drops 10°:
T-10°
It will reach 25° below zero:
T - 10° = -25°
We add 10° in both members of the equation:
T - 10° +10° = -25° +10°
The equation is simplified as follows:
T = -25° +10°
T = -15°
The integer -15° can be expressed as 15° below zero.
There are two scales, one is a Ritcher scale and another one is called a Mercalli scale.
The copper atom is oxidized while the silver is reduced.
<h3>What is a redox reaction?</h3>
A redox reaction is one that occurs between an oxidizing agent and a reducing agent. One specie is oxidized while the other specie is reduced in the reaction.
In this case, the oxidizing agent is the silver and the reducing agent is the copper atom. The copper atom is oxidized while the silver is reduced.
The complete equation is;
Cu(s) + 2AgNO3(aq) -----> Cu(NO3)2(aq) + Ag(s)
Ionically;
Cu(s) + 2Ag^+ -----> Cu^2+(aq) + Ag(s)
