To determine which has the greatest mass, we need to find out the molecular mass of each element:
Uranium (U) = 238 g/mol
Oxygen (O) = 16 g/mol
Sodium (Na) = 23 g/mol
Chlorine (Cl) = 35.45 g/mol
Therefore, if we have one mole of each element, the element with the greatest mass is 238 grams or <u>Uranium.</u><span />
Your answer would be, I believe, The same number of decimal places as the least precise values!!!!
Hope that helps!!!
Answer : The shape and bond angle of the given molecule is, bent and
respectively.
Explanation :
In the given molecule, 'Y' is the central atom and 'X' is the neighboring atom. In the given molecule, there are 4 electron pairs that means the hybridization will be
and the electronic geometry of the molecule will be tetrahedral.
But as there are two atoms around the central atom, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent or angular and the bond angle will be,
.
Hence, the shape and bond angle of the given molecule is, bent and
respectively.
