Answer:

Mass of 2 moles of $^{238}\textrm{U}$ is 476.1 g

Explanation:

We know that number of moles of an atom is ratio of mass of the atom to it's atomic weight.
Atomic weight of $^{238}\textrm{U}$ is 238.05 g/mol
So, mass of 1 mol of $^{238}\textrm{U}$ atom is 238.05 g
Hence mass of 2 moles of $^{238}\textrm{U}$ = $(2mol\times 238.05g/mol)=476.1 g$

Hence mass of 2 moles of $^{238}\textrm{U}$ is 476.1 g

The arrow shows that the bond between the chlorine atom and the fluorine atom is nonpolar. The electrons in the bond are pulled more strongly by the fluorine atom, and the chlorine atom is slightly positive.

Explanation:

The bond between Chlorine and fluorine is nonpolar bonding because both of them are sharing an equal number of electrons in the bond. H2, F2, and CL2 are common examples of this.

Chlorine and fluorine are electronegative molecules but Fluorine is above chlorine in the periodic table. Since fluorine is above Chlorine, fluorine has slightly highest electronegative nature compare to fluorine. This is the reason why Fluorine molecules are attracting electrons more than chlorine atoms. This making chlorine atoms slightly positive in Cl and F bonding.
