Answer
Reactions C and D conserve baryon number.
Work Step by Step
The baryon numbers for particles are in Table 44.3.
a. List the baryon numbers for the reactant(s): 1 + 1 = 2
List the baryon numbers for the product(s): 1 + 0 = 1
Not conserved.
b. List the baryon numbers for the reactant(s): 1 + 1 = 2
List the baryon numbers for the product(s): 0 + 0 = 0
Not conserved.
c. List the baryon numbers for the reactant(s): 1
List the baryon numbers for the product(s): 1 + 0 + 0 = 1
Conserved.
d. List the baryon numbers for the reactant(s): 1 – 1 = 0
List the baryon numbers for the product(s): 0
Conserved.
