What is the total volume of gaseous products formed when 116 liters of butane (C4H10) react completely according to the followin

Contact [7]

Answer: The total volume of the gaseous products is 1044.29 L

Explanation:

We are given:

Volume of butane = 116 L

At STP:

22.4 L of volume is occupied by 1 mole of a gas

So, 116 L of volume will be occupied by = $\frac{1}{22.4}\times 116=5.18mol$ of butane

The chemical equation for the combustion of butane follows:

$2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(g)$

For carbon dioxide:

By Stoichiometry of the reaction:

2 moles of butane produces 8 moles of carbon dioxide

So, 5.18 moles of butane will produce = $\frac{8}{2}\times 5.18=20.72mol$ of carbon dioxide

Volume of carbon dioxide at STP = (20.72 × 22.4) = 464.13 L

For water vapor:

By Stoichiometry of the reaction:

2 moles of butane produces 10 moles of water vapor

So, 5.18 moles of butane will produce = $\frac{10}{2}\times 5.18=25.9mol$ of water vapor

Volume of water vapor at STP = (25.9 × 22.4) = 580.16 L

Total volume of the gaseous products = [464.13 + 580.16] = 1044.29 L

Hence, the total volume of the gaseous products is 1044.29 L

There are many positive and negative aspects associated with nuclear power. What is a positive aspect associated with nuclear po

Keith_Richards [23]

Answer: A)There is a high ratio of energy to cost

Positives:

A Chunk of Uranium can power a city a lot longer than a chunk of coal.
It also does not contribute to pollution since what comes out of the tower is steam.

Negatives:

It is very expensive to build and maintain a nuclear power plant at first so investors whom want money up front are more reluctant to loan money for one.

If the plant does melt down it is very bad for the enviroment and its people, for example Chernobyl Nuclear Power Plant in the Ukraine will not be able to be lived in for approximently 20,000 years.
