问题:

对于下列2个反应的说法正确的:

(1)2A2+B22C (均为无色)______________

(2)X2+Y22XY 其中Y2是有色物质_____________

① 若物质均为气体,某物质的浓度、百分含量、物质的量不变了,反应达到了平衡状态

② 若物质均为气体V正(A2)= 2V逆(B2)时反应达到了平衡

③ 若物质均为气体,V逆(X2)= 1/2V(XY)时反应达到了平衡

④ ①式其他条件不变,若增大压强,平衡逆向移动,说明A、B中至少有一各是固体或液体

⑤ ②式平衡时,c(XY)=0.5mol/L, 若将容器体积扩大到原来的2倍,XY的的浓度变为0.3mol/L,则

X2、Y2中至少有一种是固体或液体。

⑥ 体系的温度不变了反应达到了平衡状态

⑦ 若物质均为气体,体系的颜色不变了,反应达到了平衡状态

⑧ 若物质均为气体,体系的平均分子量不变了,反应达到了平衡状态

The London Eye is a giant 135---meter tall Ferris wheel situated on the banks of the River Thames in the British capital. Since 20 January 2011, it has been officially known as the EDF Energy London Eye following a three---year deal with the company. It is the tallest Ferris wheel in Europe, and the most popular paid tourist attraction in the United Kingdom, visited by over 3.5 million people every year. The London Eye is located at the western end of Jubilee Gardens, on the South Bank of the River Thames In the London Borough of Lambeth in England, between Westminster Bridge( which has longer history than the famous Severn Bridge to the west of London) and Hungerford Bridge. When erected in 1999, it was the tallest Ferris wheel in the world, until surpassed first by the 160 m Star of Nanchang in 2006, and the 165m Singapore Flyer in 2008. A breathtaking feat of design and engineering, passengers in the London Eye’s capsules can see up to 40 kilometers in all directions. The London Eye is the vision of David Marks and Julia Barfield, a husband and wife architect team. The wheel design was used as a metaphor for the end of the 20th century, and time turning into the new millennium(千禧年). Back in 2000, the London Eye was known as the Millennium wheel. In 2009, a 4D Film Experience was added as a free extra to enjoy before your ride on the Eye. Once you get high enough and start coming down the other side, you will see people reach for their cameras. Here’s where the good stuff is right at your fingertips(or seems so). Parliament and Big Ben are beneath you, as are so many other historical things . If you are interested in other attractions in London, you can refer to the homepage.
