Answer

A) 2Li + 2 H2O -> 2LiOH + H2 B) Ba + 2H2O -> Ba(OH)2 + H2

Work Step by Step

A) Since lithium is in Group 1A it reacts with water to form a solution that is basic Write the skeleton equation of the reaction by changing the names to their respective formulas Balance the equation such that you have the same number of atoms of each element on each side of the equation so that mass is conserved B) Since barium is in Group 2A it reacts with water to form a solution that is basic. Write the skeleton equation of the reaction by changing the names to their respective formulas. Balance the equation such that you have the same number of atoms of each element on each side of the equation so that mass is conserved.
