Answer:
47.8 g
Explanation:
Remember the equation for percent yield:
% yield = actual / theoretical
We're given two of the values in the question, so plug n' play:
0.945 = 45.2 / theoretical
theoretical = 47.8 g
Keep in mind you can use mass here without converting to moles because we're working with products only. If you were given a mass of reactants, you would need to convert to moles and using a balanced chemical equation find the corresponding moles of product produced.
 
        
             
        
        
        
The electron geometry of TeCl6 is octahedral, while the molecular geometry is octahedral, non polar. 
Octahedral geometry or six electron pairs is the basic geometry for a molecule containing a central atom with six pairs of electrons, such as TeCl6 or SF6. As we replace bonding pairs with non bonding pairs the molecular geometry changes to square pyramidal to square planar. 
        
             
        
        
        
N₂H₄ :
N =  - 2  
H = + 1
 2 * ( -2 ) + ( 1 * 4 ) =  - 4 + 4 = 0
hope this helps!
