Decomposition of stone due to acid rain<span />
Answer:
2S + 3O 2 --->2SO 3 synthesis
Explanation:
2Na + 2H 2O -->2NaOH + H 2 single replacement
2S + 3O 2 --->2SO 3 synthesis
2H 2O 2 --->2H 2O + O 2 decomposition
CaCl 2 + F 2 ---> CaF 2 + Cl 2 single replacement
The principle of original horizontality states that all rock layers were initially deposited horizontally. The answer must be They were deposited horizontally and then shifted by a geologic event because they other choices all indicate that the the rocks were initially deposited in a way that was not horizontal.
Hope this helps!!
