Question
ic 25 - 26 physical science 1
writing and balancing chemical equations
balance the reaction by increasing or
decreasing the coefficients.
enter your answers in the boxes to show
the balanced equation.
n₂ + h₂ → nh₃
Step1: Balance el nitrógeno
Hay 2 átomos de N en el lado izquierdo (\(N_{2}\)) y 1 en el lado derecho (\(NH_{3}\)). Asignamos un coeficiente de 2 a \(NH_{3}\): \(N_{2}+H_{2}\to2NH_{3}\)
Step2: Balance el hidrógeno
Ahora, en el lado derecho hay \(2\times3 = 6\) átomos de H. En el lado izquierdo, \(H_{2}\) tiene 2 átomos de H. Asignamos un coeficiente de 3 a \(H_{2}\): \(N_{2}+3H_{2}\to2NH_{3}\)
