实验中观测到:混合气甲呈无色并被蒸馏水全部吸收;固体乙为纯净物;在步骤③中,取1/10溶液丙,恰好中和需消耗0.00200molNaOH;另取一定量的溶液丙,加入少量K2FeO4固体,产生黄绿色气体。
请回答:
(1)X的化学式是
(2)溶液丙与K2FeO4固体反应的化学方程式是

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
