They have strong intermolecular forces between their atoms, hence why more heat is necessary.
Answer:
Explanation:
There are 6 32S atoms and 2 36S atoms
Their respective contributions to the average aomic mass is (6*32)=192, and (2*36)=72. Added together, this makes 264 total. Divide by the total number of atoms, 8. (264/8) = 33.00
The weighted atomic mass of these S atoms is 33.00 amu (atomic mass units)
Answer is 0.289nm.
Explanation: The wt % of Fe and wt % of V is given for a Fe-V alloy.
wt % of Fe in Fe-V alloy = 85%
wt % of V in Fe-V alloy = 15%
We need to calculate edge length of the unit cell having bcc structure.
Using density formula,
For calculating edge length,
For calculating 
, we use the formula
Similarly for calculating 
, we use the formula
From the periodic table, masses of the two elements can be written
Specific density of both the elements are
Putting and 
formula's in edge length formula, we get
