Answer:
Answer:
step 1:balance skeleton equation the chemical equation:
Zn +HNO3➔Zn(NO3)2+NO+H2O
step 2: identity undergoing oxidation or reduction
here
Zn➔Zn(NO3)2
Zn is oxidized from 0 to 2 in oxidation no.
HNO3➔NO
N is reduced from 5 to 2 in oxidation no
Step 3: calculate change in oxidation no.
change in oxidation no
in Zn=0-2=-2=2
in
N=5-2=3
Step 4: Balance it by doing crisscrossed multiplication
we get;
3Zn +2HNO3➔3Zn(NO3)2+2NO+H2O
step 6:Balance other atoms except H & O
3Zn +2HNO3➔3Zn(NO3)2+2NO+H2O
3Zn +2HNO3+6HNO3➔3Zn(NO3)2+2NO+H2O
finally: balance H
<em><u>3Zn +8HNO3➔3Zn(NO3)2+2NO+4H2O</u></em>
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.

Answer:
Atoms are neither created or destroyed.
Explanation:
The end result of a chemical change does not create or destroy any atoms. Matter cannot be created or destroyed, meaning the same amount of atoms exist before and after the change.
