Question

Indentify the following reactions -
a) 2mg+o2=2mgo. b) nacl+agno3=agcl+NANO3. c) CuCO3 → CO2 + CuO​

Answer 1

Answer:

don't know sorryyyyyyyy friend

Explanation:

so sorry

Answer 2

Explanation:

a) 2mg+o2=2mgo

= Combination reaction

A combination reaction is a reaction where two or more elements or compounds combine to form a single compound.

Eg: Here,

Magnesium (2Mg) combines with Oxygen (O2) to form an compound named Magnesium Oxide (2MgO)

b) nacl + agno3 = agcl + NANO3

= Double Displacement reaction

A chemical process involving the exchange of bonds between two reacting chemical species which results in the creation of products with similar or identical bonding affiliations.

Eg: Here,

Sodium chloride (nacl) is displaced with Silver nitrate (no3)

to form Silver chloride (agcl) and Silver nitrate (nano3).

c) CuCO3 → CO2 + CuO

= Decomposition reaction

Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity into two or more fragments.

Eg: Here,

Copper carbonate (CuCO3 ) decomposes or breaks to form to chemical elements , Carbon dioxide (CO2) and Copper oxide (CuO).
