Question
1. Fluorine gas reacts violently with water to produce hydrogen fluoride and ozone according to the following equation. 3F2(g) + 3H2O() + 6HF(g) + O(g) divide en die standard What volumes of Oz and HF gas would be produced by the complete reaction of 3.32 x 10° mL of fluorine gas? All gases are measured under the same conditions. [2 Marks) p.s... 2. A sample of ethanol burns in O2 to form Co, and H20 according to the following equation. C2H5OH + 30, 2CO2 + 3H20 If the combustion uses 45.8 ml of oxygen measured at 3.26 atm and 45.°C, what volume of CO, is produced when measured at STP? (3 marks)Explanation / Answer
1)
from reaction,
volume of HF formed = (6/3)*volume of F2 reacted
= (6/3)*(3.32*10^4 mL)
= 6.64*10^4 mL
volume of O3 formed = (1/3)*volume of F2 reacted
= (1/3)*(3.32*10^4 mL)
= 1.11*10^4 mL
so, total volume of O3 and HF = 6.64*10^4 mL + 1.11*10^4 mL
= 7.75*10^4 mL
Answer: 7.75*10^4 mL
