Applications of Linear Systems

  1. Balance the following chemical equation. When solutions of sodium phosphate and barium nitrate are mixed, the result is barium phosphate and sodium nitrate. The unbalanced equation is
    \(\mathrm{Na}_{3} \mathrm{PO}_{4}+\mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2} \rightarrow \mathrm{Ba}_{3}\left(\mathrm{PO}_{4}\right)_{2}+\mathrm{NaNO}_{3}\)  solution
