Question

Рассчитайте, сколько килограммов древесных опилок нужно взять, чтобы в результате ряда последовательных химических реакций получить 896 л этилена (н.у.). Известно, что в древесных опилках содержится 50% чистой целлюлозы. Приведите уравнения реакций всех протекающих процессов

Answer 1

(C6H10O5)n+nH2O=nC6H12O6

C6H12O6=2C2H5OH+2CO2

C2H5OH=C2H4+H2O

n(C2H4)=896:22,4=40;n(C6H12O6)=20;n(C6H10O5)=20;

m(C6H10O5)=20*162=3240г;m(опилок)=3240:0,5=6480г;

Answer 2

Calculation of the Amount of Wood Sawdust Needed to Produce 896 Liters of Ethylene

To calculate the amount of wood sawdust needed to produce 896 liters of ethylene, we need to consider the following information:

1. Wood sawdust contains 50% pure cellulose. 2. Ethylene is produced through a series of chemical reactions.

Let's break down the calculation step by step:

Step 1: Determine the amount of cellulose in wood sawdust Since wood sawdust contains 50% pure cellulose, we can calculate the amount of cellulose in the wood sawdust by multiplying the weight of the wood sawdust by 0.5.

Step 2: Convert the amount of cellulose to ethylene To convert the amount of cellulose to ethylene, we need to know the stoichiometry of the reaction between cellulose and ethylene. Unfortunately, the specific chemical reactions involved in this process are not provided in the question or the search results.

Without the specific chemical reactions, it is not possible to accurately determine the amount of ethylene produced from a given amount of cellulose. Therefore, we cannot provide a precise calculation for the amount of wood sawdust needed to produce 896 liters of ethylene.

However, if you have the specific chemical reactions involved in the process, I would be happy to help you with the calculations.
