Answer:
D: chain of volcanoes circling the Pacific Basin
Explanation:
Answer:
C is the only option that represents an empirical formula, as it can't be simplified further.
You can turn C8H18, for example: to C4H9, but you can't do the same with C2H5.
Let me know if this helps!
Answer:
54.0 g.
Explanation:
- From the given data and the balanced reaction:
<em>2H₂ + O₂ → 2H₂O.</em>
<em></em>
When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water according to the balanced reaction.
<em>∴ The no. of grams in 3.0 moles of water = no. of moles x molar mass </em>= (3.0 mol)(18.0 g/mol) = <em>54.0 g.</em>
Answer:
D) Vitamin C is oxidized to yield a furan ring with 3 carbonyl groups and no double bonds
Explanation:
We can tell that the compound " (5R)-5-[(1S)-1,2-dihydroxyethyl]-3,4-dihydroxy-furan-2,3,4(5H)-trione " has 3 carbonyl groups due to it having "trione" in the name (and it lacking other carbonyl group names, like amide or carboxylic acid).
As there is no "-ene" part of the name referencing a double bond, the only option left is option D).
