Question

identify the combination and decomposition reaction a) KCL=K+1/2CL2 b) NH3+HCL=NH4CL c) 2SO2+O2=2SO3 d) 2NH3=N2+3H2 ​

Answer 1

Answer:

a) decomposition reaction

b)combination reaction

c) combination reaction

d) decomposition reaction

Explanation:

Combination reaction: A chemical reaction in which two or more reactants combine to form a single product.

Decomposition Reaction:A chemical reaction in which a single reactant is split into two or more products

Answer 2

Answer:

a - decomposition reaction

b - combination reaction

c - combination reaction

d - decomposition reaction

Explanation:

• combination reaction -- A reaction in which two or more substances react to form a single product .ex - 2Mg( s) + o2 = 2Mgo(s)
• decomposition reaction -- A reaction in which Single substances formed two or more substances. ex--- A=b+c
