Answer:
B:GRANITE
Explanation:
<em>Granite is typical of a larger family of granitic rocks that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals.</em>

These properties have made granite a widespread construction stone throughout human history.</em>

Answer:
Name of the compound is Nitrogen triiodide.
Explanation:
According to the IUPAC rules, to naming of the compound the following formula can be applied.
Prefix + Name of first element + Base name element of second element + Suffix.
The given compound - 
Name of first element- Nitrogen
Base name element of second element - Iodine
Suffix = 3 = tri
Here, iodine is in ionic form therefore, it becomes iodide. and then suffix will be added in front of the halogen.
Therefore, name of the compound will be Nitrogen triiodide..
I think the answer is letter B.
the first law says that the change in internal energy of a system is given by:
δ<span>E = δq + δw</span>
where δ<span>E is the i change in internal energy, </span>
<span>δq is the amount of thermal energy added to the system from the surroundings </span>
<span>δw is the l work done *on* the system *by* the surroundings. </span>
<span>For a system only undergoing expansion work,
δw = -p</span>δ<span>V, so: </span>
δE = δq - p δ<span>V </span>
when δV = 0, then δe=δq
The bond<span> length in a </span>molecule<span> of </span>KBr<span> is measured to be 282.1 pm, compared with a </span>nonpolar<span> covalent radius sum for K and Br of 310,4. </span>
