Answer:
The unit cell edge lenght in pm is equal to 361 pm
Explanation:
Data provided:
ρ=Copper density=8.96 g/cm3
Atomic mass of copper=63.54 g/mol
Atoms/cell=4 atoms (in theory)
Avogadro's number=6.02x
atoms/mol
Since copper has a cubic structure, its cell volume is equal to 
, which can be obtained through the relationship:
cell volume=
Substituting the values:
cell volume=
clearing, we have:
a=![\sqrt[3]{4.71x10^{-23}cm^{3} }=3.61x10^{-8}cm](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4.71x10%5E%7B-23%7Dcm%5E%7B3%7D%20%20%7D%3D3.61x10%5E%7B-8%7Dcm)
We convert from centimeter to picometer, 1cm=1x

Answer:
B) The amount of vitamin D gained in 1 day.
Explanation:
Answer:
107.8
Explanation:
64 gram of N2H4 produce 72 gram of H20
then by crossmultiplication
64*121.3/72=107.82
Answer:
4- A material that transfers heat energy more easily than another material will experience a greater rate of thermal energy loss than an object that does not transfer heat energy easily.
Explanation:
Thermal energy loss has to do with loss of heat energy by a body to another body or its environment. The aim of the process is usually the attainment of thermal equilibrium between the body and its environment.
On a cold day, a material that transfers thermal energy more easily will loose thermal energy faster than an object that does not transfer thermal energy. The rate of heat transfer of a body determines its rate of loss of thermal energy.
