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