Question

NAME THE TYPE OF CHEMICAL REACTION REPRESENTED BY THE FOLLOWING EQUATIONS :

1) CACO2(S) ---heat----->CAO(S) +co2(g)

2) Cao (s) + h2o (l) ---heat--->ca(oh)2 (aq)

3) Zn (s) +h2so4(aq) ---heat---> Znso4(aq) +h2(g)

no spam plz

Answer 1

hey!!
here is ur answer
chemical reaction involved in all the three cases are -
1.decomposition reaction(bcoz here one compound breaks into simpler compound)
2.combination reaction(here simpler compound combines to form a single complex compound)
3 displacement reaction(here more reactive metals displaces the less reactive metal from it's compound that's why displacement reaction)

hope it helps

Answer 2

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Name of chemical reactions which are given above are given below :

1 ))➡️ DECOMPOSITION REACTION ( THERMAL DECOMPOSITION REACTION )

✔️ because single compounds breaks down to give more than two substances.

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐


2 ))➡️ COMBINATION REACTION

✔️ because more than one substances combine to form single compound.

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

3 ))➡️ DISPLACEMENT REACTION

✔️ more reactive element displaces less reactive metal from its salt solution.

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

I hope it will help you a lot

Thanks
