Agno3+al complete and balance the equation for this single displacement

The balanced chemical equation is written below.

Explanation:

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

When aluminium metal reacts with silver nitrate, it leads to the formation of a salt known as aluminium nitrate and also silver metal.

The chemical equation for the above reaction follows:

By Stoichiometry of the reaction:

3 moles of silver nitrate reacts with aluminium metal to produce 1 mole of aluminium nitrate and 3 moles of silver metal.

Hence, the balanced chemical equation is written above.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
