A sample of oxygen gas at a pressure of 690 mmHg and a temperature of 32°C occupies a volume of 14.2 L if the gas is cooled at constant pressure to a temperature of -1°C the volume of the gas sample will be

12.66 L

Explanation:

- Used combined gas law formula

- Change C to K

- Rearrange formula to fit your values

dishwashers don't have rights

explanation:

dishwashers are meant for one thing and one thing only: dishwashing. they belong in the kitchen making sandwiches and cleaning up for the man of their household. if your dishwasher starts acting up just slap it and wait a minute.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
