Explanation:
Below is an attachment containing the solution.
Answer:
a. Negative
b. Positive
c. Negative
d. zero
Explanation:
Entropy is measure of disorder. Positive entropy implies that a system is becoming more disordered. The opposite is true.
(a) N2(g)+3H2(g) → 2NH3(g) Negative because the system is becoming less disordered since the number of gaseous moles is decreasing
(b) CaCO3(s)→CaO(s)+CO2(g) Positive because a solid produces a gas which is more disorder therefore there is an increase in entropy
(c) 3C2H2(g)→C6H6(g) Negative because the number of moles of a gas decrease meaninng there is less disorder
(d) Al2O3(s)+3H2(g) → 2Al(s)+3H2O(g) zero because the gaseous moles do not change
The correct answer among the choices listed above is the last option. All of the following release carbon into the atmosphere except the <span>sedimentation of dead organisms. Combustion or burning always include the release of carbon dioxide into the atmosphere as well as the cellular respiration of plants and animals.</span>
Answer:reaction 1 because a single product is formed
Explanation: all the reactions are being form into two separate products while in reaction 1 is transforming two different products in two one product all together.
