PLEASE, I REALLY NEED HELP The following are artificial nuclear reactions that occur by bombardment. Balance each equation, identifying the missing particles' mass number, atomic number, and element symbol:

238/92 U + 14/7 N ---> _ + 5 1/0 n

252/98 Cf + _ ---> 257/103 Lr + 5 1/0 n

57/24 Cr + 4/2 He ---> _ + 56/26 Fe

40/18 Ar + 4/2 He ---> _ + 1/1 H

Answer(28.02g/mol);

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -

This is called a hybrid.
