Answer:
Explanation:
Let recall the crystal structure of CsBr obtains a BCC structure. In a BCC structure, there exist only two atom per cell.
The density d of CsBr in g/cm³ can be calculated by using the formula:
where;
z = 1 mole of CsBr
edge length = 428.7 pm = (4.287 × 10⁻⁸)³ cm
molar mass of CsBr = 212.81 g/mol
avogadro's number = 6.023 × 10²³
Answer:
See below.
Step-by-step explanation:
The author is probably reminding us that knowing the origins of words helps us to remember what they mean.
If "verde" means "green", the "verd" in "verdigris" probably means that verdigris is green.
However, the "verd" in verdigris domes from other languages.
It was originally Latin "viride aeris" (green brass).
In old French it became "verte de Grèce" (green of Greece). The modern French spelling is "vert-de-gris" (green of grey).
The English word "verdigris" comes from the French words.
