<span>All the processes that physically disintegrate or chemically decompose a rock at or near the earth's surface is called w</span>eathering.
<span>Weathering produces sediment, whereas erosion transfers sediment from place to place.</span>
Answer:
6.2 g
Explanation:
In a first-order decay, the formula for the amount remaining after <em>n</em> half-lives is
where
<em>N</em>₀ and <em>N</em> are the initial and final amounts of the substance
1. Calculate the <em>number of half-lives</em>.
If
2. Calculate the <em>final mass</em> of the substance.
The balanced chemical equation for the <span>combustion of ethane is
2C</span>₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
The stoichiometric ratio between C₂H₆(g) and CO₂(g) is 1 : 2
Hence,
moles of CO₂(g) produced = moles of reacted C₂H₆(g) x 2
= 1.00 mol x 2
= 2.00 mol
Hence, the correct answer is "C".
I hope this helps you alot and to my understanding:)
I believe the answer to your question is <span>valence atoms.</span>
