Answer:
64 kg
Explanation:
The computation of the number of kg need to ordered is shown below:
As we know that
Now as we know that
1 mole of 
generated from 1 mole of 
Now
26g of generated from 64g of
And,
26kg of generated from
= 
= 64kg
Hence, the number of kg that required for ordering the calcium carbide is 64 kg
Any moving object has kinetic energy
40 g Ar.......6.023*10^23 atoms
x g Ar.......3.8*10^24 atoms
x=40*3.8*10^24/(6.023*10^23)=252,365g Ar
A large atom means that the radius would be large, meaning that the effective nuclear charge is low, therefore a lower electronegativity based on the periodic table. A smaller atom would mean the opposite, therefore a higher electronegativity. This combination would mean that the new molecule is polar.
Also, to answer your question, it would be most likely different from both atoms, as size doesn't really matter in a compound's properties.
Wow thats pretty hard its asking how many is in each of those
