Answer:
Explanation: Water cycles through the biosphere as part of the water cycle. ... For example, gravity also pulls water from higher elevations in mountains and hills to low lying areas, whether these areas are oceans, lakes, or simply land (in which case the water is likely absorbed by plants or evaporates).

167g. Because the law of conservation of mass says that matter can not be created or destoryed, in a chemical reaction.
Answer:
See explanation
Explanation:
On the pH scale acidity ranges from pH values of 0-6.9. Natural rain water is slightly acidic due to the presence of carbon dioxide in the atmosphere which is an anhydride of carbonic acid.
CO2(g) + H2O(l) -------> H2CO3(aq)
B. The equations that turn sulfur to sulfuric acid are;
S(l) + O2(g) -----> SO2(g)
2SO2(l) + O2(g) -----> 2SO3(g)
SO3(g) + H2SO4(l) -----> H2S2O7(l)
H2S2O7(l) + H2O(l) ----> 2H2SO4(l)
-
At pH 6, H^+ concentration = 1 * 10^-6 M
At pH 2, H^+ concentration = 1 * 10^-2 M
Hence;
1 * 10^-2/1 * 10^-6
= 10^4 times more acidic
Adding energy can put the reaction in a state of equilibrium because more energy allows the reverse reaction, which is endothermic, to occur along with the forward reaction
