Identify the following redox reactions by type. check all that apply. (a) fe + h2so4 → feso4 + h2 combination decomposition displacement disproportionation (b) s + 3f2 → sf6 combination decomposition displacement disproportionation (c) 2cucl → cu + cucl2 combination decomposition displacement disproportionation (d) 2ag + ptcl2 → 2agcl + pt combination decomposition displacement disproportionation

Answer :

(a) displacement reaction

(b) combination reaction

(c) disproportionation reaction

(d) displacement reaction

Explanation :

(a) The given balanced chemical reaction is,

This reaction is a single replacement reaction or displacement in which the the more reactive element (Fe) replace the less reactive element (H).

(b) The given balanced chemical reaction is,

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or single product.

(c) The given balanced chemical reaction is,

This reaction is a disproportionation reaction in which the chemical species gets oxidized and reduced simultaneously.  It is also considered as a redox reaction.

(d) The given balanced chemical reaction is,

This reaction is a single replacement reaction or displacement in which the the more reactive element (Ag) replace the less reactive element (Pt).
