Which figure best represents what will happen when Pb(NO3)2(aq) is treated with an excess of NaCl(aq)? Water molecules are omitted for clarity.

What is the theoretical yield (in grams) of iron(III) carbonate that can be produced from 1.72 g of iron(III) nitrate and an excess of sodium carbonate?  The molar mass of iron(III) carbonate, Fe2(CO3)3, is 291.73 g/mol, and the molar mass of iron(III) nitrate, Fe(NO3)3, is 241.88 g/mol. 2Fe(NO3)3(aq) + 3Na2CO3(aq) → Fe2(CO3)3(s) + 6NaNO3(aq)

11. Superposition Principle: If two or more traveling waves are moving through a medium, the resultant value of the wave function at any point where the waves both exist is the algebraic sum of the values of the wave functions of the individual waves at that point.
