a C6H5NH2 + b HCl = c C6H5NH3Cl Step 2: Create a System of Equations Create an equation for each element (C, H, N, Cl) where each term represents the number of atoms of the element in each reactant or product. C: 6a + 0b = 6c H: 7a + 1b = 8c N: 1a + 0b = 1...
d、c(N2):c(H2):c(HCl)=1:3:6③上述反应达到平衡后,下列说法正确的是 ;a、共他条件不变,压强增大,平衡常数K减小b、其他条件不变,温度升高,平衡常数K减小c、其他条件不变,增大Si3N4物质的量平衡向左移动d、他条件不变,增大HCl物质的量平衡向左移动(4)巳知0.01mol/l的亚硝酸(HNO2)溶液pH>2.则0.01...
