What are the signs of delta s, delta h and delta g for the formation of dew on a cool night? all the s ,h and g values are delta values, i'm just not going to write delta for each one.
a) +s, +h, +g
b) +s, +h, -g
c) +s, -h, +g
d) +s, -h, -g
e) -s, +h, +g
f) -s, +h, -g
g) -s, -h, +g
h) -s, -h, -g
pls me, i'm so confused and this question has so many different options its overwhelmingg

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
