Answer:1
Explanation: friction is showing us how in the past
Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!
The answer to your question is
D) Blowing sand can wear away a rock's surface and break it into smaller pieces
When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.
Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.
I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.
Please give me brainliest if I was correct and helpful!
Otherwise, please comment and let me know how I can fix my answer!
Thank you, it was fun, have a nice week!
Answer:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).
Explanation:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
2H₂O(g) → 2H₂O(l)
- To add the two equations: we omit H₂O(g) that is formed by 2 moles in the product side of the first equation and consumed by 2 moles from the reactants side in the second equation
- So, the overall chemical equation is obtained by combining these intermediate equations is:
<em>CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).</em>
