In an experiment, 12.0dm3 of oxygen, measured under room conditions, is used to burn completely 0.10mol of propan-1-ol. what is the final volume of gas, measured under room conditions? a 7.20dm3 b 8.40dm3 c 16.8dm3 d 18.00dm3 ans is b. pls explain how

The correct answer is option D.

Explanation:

At room conditions ,temperature is taken as T =293.15 k

At room conditions, pressure is taken as P = 1 atm

Given the volume of oxygen gas = = 12.0 L

Using Ideal gas equation:

n = 0.4992033 moles of oxygen gas.

Initial number of moles of oxygen gas = 0.4992 mol

According to reaction, 2 moles of propanol reacts with 9 moles of oxygen.

Then 0.10 moles of propanol will react with:

Final moles of oxygen gas left after combustion reaction = n'

n'= 0.4992 mol - 0.45 mol = 0.0492 mol

So, the final volume of the oxygen gas measured will be given as:V'

V' = 1.18 L

Volume of the

According to reaction, 2 moles of propanol gives  with 6 moles of .

Then 0.10 moles of propanol will give :

Volume of the

According to reaction, 2 moles of propanol gives  with 8 moles of .

Then 0.10 moles of propanol will give :

Total volume of the gas measured =

i'm assuming that it's c.) red bank..

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
