13. 14. 15. 16. 10cm of methane (CH4) gas is exploded with 150cm of air containing 20% oxygen and 80% nitrogen. The products were allowed to cool to room temperature. What will be the total volume of the gases at the end of the reaction? Give the open structures of:- (i) 3-chlorohex-l-yne (ii) CH3OH A fixed mass of gas occupies 105cm at -14C and 650mmHg pressure. At what temperature in degrees Celsius will it have a volume of 15cm if the pressure is adjusted to 690mmHg pressure? Write an equation for the reaction that takes place between ethene and concentrated Sulphuric (VI) acid
