<span>Ethane reacts with oxygen to yield carbon dioxide and liquid water. I believe the correct answer from the choices listed above is option B. The correct equation for this reaction would be as follows:
</span><span>c2h6 (g) + o2(g) = co2(g) + h2o(l)
Hope this answers the question. Have a nice day.</span>
Answer:
3.53 g
Explanation:
To convert from atoms to moles, you need to know Avogadro's number. Avogadro's number (6.022 × 10²³) is how many atoms there are in one mole of a substance. Use this to convert.
(1.97 × 10²² atoms) ÷ (6.022 × 10²³ atoms/mol) = 0.0327 mol
Now that you have moles, use the molar mass to convert to grams.
(0.0327 mol) × (107.87 g/mol) = 3.53 g
Answer: the mixing of ones s and two p atomic orbitals
