(A)保持体积不变,外高温度,体系中混和气体的密度一定减小 (B)增大压强,降低温度,体系中混和气体的平均分子量一定增大 (C)保持温度、体积不变,增加CO_2,达到新平衡时混和气体的平均分子量一定增大 (D)保持温度、压强不变,增加CO_2,达到新平衡时混和气体的平均分子量依然如前 3、某氯原子的质量为a克,1个~(12)C原子的质量为b克,若用N_A表示阿佛加德罗常数,则下列说法正确的是( )
(A) Keep the volume constant, outside the high temperature, the density of the mixed gas in the system must be reduced (B) increase the pressure, reduce the temperature, the average molecular weight of the mixed gas in the system must increase (C) maintain the temperature, the same volume , increase CO 2 , when the new equilibrium is reached, the average molecular weight of the blended gas must increase (D) maintain the temperature and pressure constant, increase CO 2 , and the average molecular weight of the blended gas is still the same as in the new equilibrium. 3, the mass of a certain chlorine atom is a g, the mass of 1 ~(12)C atom is bg. If N_A is used to represent Avogadro’s constant, the following statement is correct ()
