第36题:将a摩H_2S和1摩O_2置于一个容积可变的容器内进行反应。维持容器内气体压强不变(101千帕),在120℃下测得反应前后容器内气体的密度分别为d_1和d_2。若a的取值不同,则H_2S的氧化产物可能有如下三种情况: (1)全部是SO_2,此时a的取值范围是__。 (2)全部是S,此时a的取值范围是__,并且d_1d_2(填小于、大于、等于) (3)部分是SO_2,部分是S,此时a的取值范围是__。① 反应所生成的SO_2的物质的量是__摩。② 容器内气体的物质的量之和为__摩。③ 对该题的第(3)问(即第三种情况)提出七种解法,是本文的主要意图。但第(3)问与第(1)、(2)问题有某些牵连,因此先将第(1)、(2)问解析如下,以便展开本文的思路。
Question 36: Place a Mohs H_2S and a Mozambique O_2 in a variable volume container and respond. The gas pressure in the vessel was kept constant (101 kPa). The gas densities in the vessel before and after the reaction were measured at 120°C and were d_1 and d_2, respectively. If the value of a is different, the oxidation products of H 2 S may have the following three conditions: (1) All of them are SO 2 , and the value range of a is __. (2) All is S. In this case, the value range of a is __, and d_1d_2 (fill in less than, greater than, or equal to) (3) The part is SO_2, and the part is S. In this case, the value range of a is __. 1 The amount of SO 2 produced by the reaction is _____. 2 The sum of the amount of gas in the container is _____. 3 Seven solutions to the (3) question (ie, the third case) of this question are the main purpose of this article. However, Part (3) and (1) and (2) have some implications, so we will first analyze (1) and (2) as follows in order to develop the idea of this article.
