2 2Hgo___2Hg+O2
3 Fe+CuSo4____feso4+cu
4 pbo2+so2____pbso4​

Answer 1

Answer:

1 DOUBLE DISPLACEMENT

2 DECOMPOSITION

3 DISPLACEMENT

4 COMBINATION

PLZ MARK AS BRAINLIEST ANSWER....

Answer 2

1.THE FIRST EQUATION IS BALANCED AND IT IS DOUBLE DISPLACEMENT REACTION.

2.EVEN THE SECOND ONE IS BALANCED AND IT IS DECOMPOSITION REACTION.

3.IT IS A BALNCED REACTION AND IT IS SINGLE DISPLACEMENT REACTION.

4.IT IS A DIRECT COMBINATION REACTION AND IS BALANCED.

REASONS ABOUT THE TYPE OF REACTION THEY ARE.

1.IT IS A DOUBLE DISPACEMENT REQCTION AS THE IONS OF BOTH THE SUBSTANCES ARE DISPLACING EACH OTHER IN THEIR AQUEOUS SOLUTION.

2.IT IS DECOMPOSITION REACTION AS THE A SINGLE COMPOUND IS DECOMPOSING OR SPLITTING,IN TWO DIFFERENT SUBSTANCES.

3.IT IS A SINGLE DISPLACEMENT REACTION AS ONLY ONE IS DISPLACING THE OTHER ELEMENT AND THE ONE WHICH GOT DISPLACED IS INDEPENDENT.

4.IT IS DIRECT COMBINATION REACTION AS TWO COMPOUNDS TOGETHER IS COMBINING WITH EACH OTHER AND IS FORMING A SINGLE COMPOUND.

HOPE YOU UNDERSTAND MY ANSWER.
