Chemical reactions might be fast -- burning gasoline, or slow -- rusting. Usually the require two or more reactants. Most of these, along with requiring more than 1 substance, also requires something to get it started ... burning needs a spark to start it.
Nuclear decay only requires 1 thing, the radioactive element. Wait and it spontaneously undergoes decay.
When a solute, sugar in this case, is added, the boiling point of the solution increases. Additionally, the melting point decreases.
To answer your question,
The boiling point of pure water is lower than sugar-water solution.
The melting point is higher for pure water than for sugar-water solution.

Chemical formulas for ionic compounds are written in lowest common multiples of the charges of each ion. This is true unlike covalent compounds where the transformation to lowest common multiple is not applicable such that this reflects to the naming of covalent compounds using prefixes mono-, di-, tri-, tetra-, etc. Answer is a.
Characteristics of a Precipitate:
A precipitate is characterized by the following properties:
Appears as a solid species.
Settled down at the bottom of the reaction pot.
Insoluble in the corresponding solvent.
Answer:
Collecting residue samples.
Explanation:
All the other given options are equally important on the exploration of a bomb aftermath.
The most important task is the collection of residue samples since it needs highly skilled personel to collect accurate samples for later on analysis.
Identification of meaningful collection areas is a technical skill that requires the most experienced team memebers.
