I think it’s to long to fit in a period??
Answer:
b, H2O(s) r H2O(g)
Explanation:
entropy is heat, so increase in heat would mean water gets evaporated or melted, or both in this case. so the only choice above that showed increase in heat is from solid(ice) to gas(water vaper) due to increase in heat in the reaction.
Answer:
the other variable is also doubled

K + S = K2S
Potassium reacts with sulfur to produce potassium sulfide
B is true if we subtract atomic number(the number of protons )from the mass number
we can find neutrons.
hope this helps
