Which statements are inconsistent with dalton's atomic theory as it was originally stated?

Missing question:

A. All carbon atoms are identical.

B. An oxygen atom combines with 1.5 hydrogen atoms to form a water molecule.

C. Two oxygen atoms combine with a carbon atom to form a carbon dioxide molecule.

D. The formation of a compound often involves the destruction of one or more atoms.

Answer is: B and D.

A is correct because Daltan stated: All atoms of a given element have the same mass and other properties that distinguish them from the atoms of other elements.

C is correct because atoms combine in simple, whole- number ratios to form compounds, B is incorrect because ratio is not simple, whole number.

D is incorrect because according to Dalton. atoms can't be created or destroyed.

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 :
