Answer:
Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant.
Explanation:
Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side.

Answer:
radius = 156 pm
Explanation:
The relation between radius and edge length of unit cell of BCC is
r=a/4
Given
a = 360 pm
Therefore
r = r = radius = 360/4= 155.88 pm
Or
156 pm
