Balancing chemical equations practice – Ninja Welcome to Balancing chemical equations practice - NinjaBalance the following equation. What is the number in front of O_{2}? [Hint: Final answer should not be in fractions or decimals] C_{5}H_{11}NH_{2} + O_{2} → CO_{2} + H_{2}O + NO_{2} Balance the following equation. What is the number in front of KNO_{3}? KNO_{3} + C_{12}H_{22}O_{11} → N_{2} + CO_{2} + H_{2}O + K_{2}CO_{3} Balance the following equation. What is the number in front of NH_{4}NO_{3}? H_{3}PO_{4} + (NH_{4})_{2}MoO_{4} + HNO_{3} → (NH_{4})_{3}PO_{4}⋅12MoO_{3} + NH_{4}NO_{3} + H_{2}O Balance the following equation. What is the number in front of K_{3}[Fe(C_{2}O_{4})_{3}]⋅3H_{2}O? FeC_{2}O_{4}⋅2H_{2}O + H_{2}C_{2}O_{4} + H_{2}O_{2} + K_{2}C_{2}O_{4} → K_{3}[Fe(C_{2}O_{4})_{3}]⋅3H_{2}O Balance the following equation. What is the number in front of H_{2}O? CaHPO_{4}⋅2H_{2}O + NaOH + H_{2}O → Na_{2}HPO_{4}⋅12H_{2}O + Ca(OH)_{2} All done? Click submit to receive your results on the next page. Time's up
