What is the oxidizing agent in the reaction fe + agno3 fe(no3)3 + ag?
valentina_108 [34]
Answer;
             Silver is acting as oxidizing Agent.

Explanation:

The reaction is as follow,

<span>                              Fe + 3 AgNo</span>₃    →     Fe(NO₃)₃<span> + 3 Ag

In above reaction the Iron's oxidation state has changed from 0 to +3, i.e. 

                             Fe</span>⁰      →     Fe³⁺  +  3 e⁻

It shows that Iron has lost 3 electrons, Hence, it is oxidized and has transferred 3 electrons to 3 mole of Ag⁺ to reduce it into Ag. Therefore, Iron is acting as reducing Agent.

While, In reaction the Silver's oxidation state has changed from +1 to 0, i.e. 

                             3 Ag⁺  +  3 e⁻     →     3 Ag

It shows that Silver has gained one electron, Hence, it is reduced and has gained 3 electrons from 1 mole of Fe to oxidize it into Fe³⁺. Therefore, Silver is acting as oxidizing Agent.

What is the specific heat capacity of a 70 g sample of an unknown metal that releases 6700J of heat when it cools from 90 to 25
swat32
Q = mCpΔT —> Solve for Cp —> Cp = q/mΔT

q = -6700 J (negative because it released heat
m = 70 g
ΔT = Final temp - initial temp = 25 - 90 = -65°C

Cp = -6700 J / (70 g)(-65°C) = 1.47 J/g°C

sdas [7]
The first object because the more mass the hard it is to hold and the density it has which is the mass, the reason why one sunk and the other didn’t is because the higher the mass the faster the object would sink
