Explanation:
Answer:
The answer is D) White Light!
Answer:
Boiling Point and Melting point = Condensation Point and Freezing Point
Explanation:
Such is easily seen on the 'Heating Curve for Water' (see attached). Note the regions that have zero slope. Trace back to y-axis of graph. These points are the phase transition temperatures for freezing (Iiquid => solid)/melting of ice (solid => liquid) and boiling of water (liquid => gas) / condensation (gas => liquid).
Note also, during phase change (heating or cooling), two phases will always be present (solid & liquid) or (liquid & gas) and experience 0 temperature change during the transitions (zero slope regions). The regions having slope values are heating or cooling of pure single phase form of the substance and do not represent phase change in those regions.

1s __
This is two electrons with opposed spin in the same orbital. The arrows with opposed directions are used to represent the opposed spins.

Theoretical yield:
02 -> H2O
1mol -> 2mol
2mol -> 4mol
32g -> 72g
Theoretical yield = 72g
Percent yield = actual yield/theoretical yield * 100
= 33.1/72 *100
=45.97%
