4. The unbalanced equation for the reaction between aqueous solutions of aluminum nitrate and sodium phosphate is as follows: Al(NO_(3))_(3)(aq)+Na_(3)PO_(4)(aq)arrow NaNO_(3)(aq)+AlPO_(4)(s) What are the coefficients for balancing this chemical equation? 1,1,3,1 3,1,3,4 3,9,3,1 1,1,1,1

To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.<br /><br />The unbalanced equation is:<br />$Al(NO_{3})_{3}(aq)+Na_{3}PO_{4}(aq)\rightarrow NaNO_{3}(aq)+AlPO_{4}(s)$<br /><br />To balance the equation, we need to find the coefficients that make the number of atoms of each element equal on both sides.<br /><br />Let's start by balancing the aluminum (Al) atoms. There is 1 Al atom on the left side and 1 Al atom on the right side, so the Al atoms are already balanced.<br /><br />Next, let's balance the nitrogen (N) atoms. There are 3 N atoms on the left side and atom on the right side, so we need to put a coefficient of 3 in front of $NaNO_{3}$ on the right side.<br /><br />Now, let's balance the sodium (Na) atoms. There are 3 Na atoms on the left side and 3 Na atoms on the right side, so the Na atoms are already balanced.<br /><br />Finally, let's balance the phosphate (PO_{4}) groups. There is 1 PO_{4} group on the left side and 1 PO_{4} group on the right side, so the PO_{4} groups are already balanced.<br /><br />The balanced equation is:<br />$Al(NO_{3})_{3}(aq)+Na_{3}PO_{4}(aq)\rightarrow 3NaNO_{3}(aq)+AlPO_{4}(s)$<br /><br />Therefore, the coefficients for balancing this chemical equation are 1, 1, 3, 1.
