Ammonium hydrogen phosphate ((NH_(4))_(2)HPO_(4)) , a common fertilizer.is made by reacting phosphoric acid (H_(3)PO_(4)) with ammonia according to the following reaction. 2NH_(3)+H_(3)PO_(4)arrow (NH_(4))_(2)HPO_(4) What is the ratio of NH_(3) to H_(3)PO_(4) NH_(3):H_(3)PO_(4)=2:square

To determine the ratio of $NH_{3}$ to $H_{3}PO_{4}$ in the reaction, we need to look at the coefficients in the balanced chemical equation.<br /><br />The balanced chemical equation for the reaction is:<br />$2NH_{3} + H_{3}PO_{4} \rightarrow (NH_{4})_{2}HPO_{4}$<br /><br />From the equation, we can see that the coefficient for $NH_{3}$ is 2, and the coefficient for $H_{3}PO_{4}$ is 1.<br /><br />Therefore, the ratio of $NH_{3}$ to $H_{3}PO_{4}$ is 2:1.<br /><br />So, the answer is:<br />$NH_{3}:H_{3}PO_{4} = 2:1$
