Answer:
O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.
Answer:
B. 4 K + O₂ → 2 K₂O
Explanation:
<em>Which of the following correctly shows a synthesis reaction involving potassium?</em>
A. Br₂ + 2 KI → I₂ + 2 KBr
No, this is a single displacement reaction, in which Br displaces I from its salt.
B. 4 K + O₂ → 2 K₂O
Yes, this is a synthesis reaction, in which 2 elements combine to form a compound.
C. 2 KClO₃ → 2 KCl + 3 O₂
No, this is a decomposition reaction, in which a big substance decomposes into smaller ones.
D. 2 K₂O → 4K + O₂
No, this is a decomposition reaction, in which a big substance decomposes into smaller ones.
