Answer: entropy, increase
Explanation:
During the sublimation of carbon dioxide, the disorder and the entropy of the system increase. Hope this works :)
<span>Chemical reaction is:
Zn+PbS<span>O4</span>→ZnS<span>O4</span>+P<span>b
</span></span>From the balanced equation 2 moles of Zn make 2 moles of ZnSO4
<span>You have 0.534 moles of zinc so you make 0.534 moles of ZnSO4. </span>
Molar mass of ZnSO4 = 161 g/mol
mass = no of moles * molar mass
mass = 0.534 * 161
mass = 85.974 g
