不需要复合状态[如(s)(aq)或(g)]。 你可以用小括号()或括号[ ]。 例子 NH3 + HBrO3 = NH4BrO3 La + I2 = LaI3 Zn + HNO3 = NO + Zn(NO3)2 + H2O CaI2 + Cl2 = CaI2 + Cl C4H9OH + KMnO4 + H2SO4 = C3H6O2 + MnSO4 + K2SO4 + H2O ...
The current NH3 production is over 200 million tons annually, mainly relying on the energy-intensive Haber–Bosch process under high temperature and pressure [1]. As such, ca. 1–2% anthropogenic energy is consumed each year to meet the global NH3 demand, accompanied by the emission of ...
