A geologist is studying an area where stream erosion and deposition are the dominant surface processes. He notices that all of t

he rock layers in the shallow streambeds have dune features preserved throughout them. Knowing that dunes are formed by the wind in desert settings, what can the geologist conclude about the geologic history of this area? A. The depositional environment has changed from stream-dominated in the past to wind-dominated today. B. Wind must still be the dominant factor shaping the surface today. C. Dunes must also form from streams, at least in this area. D. The depositional environment has changed from wind-dominated in the past to stream-dominated today.

Use the chemical equation and the bond diagram to answer the question.
Scilla [17]

Answer:

O=O bond

Explanation:-

Note it down that the bond having highest Hydrogen enthalpy has strongest bond.

Now

  • O=O(495KJ/mol)
  • O-O(146KJ/mol)
  • O-H(467KJ/mol)
  • H-H(432KJ/mol)

Hence

\\ \bull\sf\dashrightarrow O=O>O-H>H-H>O-O

What volume of oxygen gas is released at STP if 10.0 g of potassium chlorate is decomposed? (The molar mass of KClO3 is 122.55 g
ArbitrLikvidat [17]
<span>KCl<span>O3</span><span>(s)</span>+Δ→KCl<span>(s)</span>+<span>32</span><span>O2</span><span>(g)</span></span>

Approx. <span>3L</span> of dioxygen gas will be evolved.

Explanation:

We assume that the reaction as written proceeds quantitatively.

Moles of <span>KCl<span>O3</span><span>(s)</span></span> = <span><span>10.0⋅g</span><span>122.55⋅g⋅mo<span>l<span>−1</span></span></span></span> = <span>0.0816⋅mol</span>

And thus <span><span>32</span>×0.0816⋅mol</span> dioxygen are produced, i.e. <span>0.122⋅mol</span>.

At STP, an Ideal Gas occupies a volume of <span>22.4⋅L⋅mo<span>l<span>−1</span></span></span>.

And thus, volume of gas produced = <span>22.4⋅L⋅mo<span>l<span>−1</span></span>×0.0816⋅mol≅3L</span>

Note that this reaction would not work well without catalysis, typically <span>Mn<span>O2</span></span>.
