Which three temperature readings all mean the same thing?

373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

273 Kelvin, 0 degrees Celsius, 212 degrees Fahrenheit

100 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit

273 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

am i too late?

explanation:

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 :

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
