Barium Cynanide is the compound
Answer:
double replacement
Explanation:
The reaction equation is given as:
Pb(NO₃)₂ + 2KI → PbI₂ + KNO₃
This reaction is a double displacement reaction.
In this form of reaction, there is an actual exchange of partners to form new compounds.
AB + CD → AD + CD
One of the following condition serves as driving force for the reaction:
- formation of an insoluble compound
- formation of water or any other non-ionizing compound
- liberation of a gaseous product.

Answer:
Washing hands with soap and water. Sanitizers are only used if there is no soap and water.
H₂O₂ + 2FeSO₄ + H₂SO₄ → Fe₂(SO₄)₃ + 2H₂O
H₂O₂ + 2H⁺ + 2e⁻ → 2H₂O k=1
Fe²⁺ → Fe³⁺ + e⁻ k=2
H₂O₂ + 2H⁺ + 2Fe²⁺ → 2H₂O + 2Fe³⁺
