Which scientist is correctly matched with his contribution to atomic theory? rutherford inferred the existence of a dense, positively charged nucleus based on results of a scattering experiment. bohr confirmed the existence of protons in the nucleus. einstein carried out the photoelectric effect experiment to show that light has particle-like properties. schrödinger proposed a planetary model of the atom to explain the emission spectrum of hydrogen.

Answer

Rutherford inferred the existence of a dense, positively charged nucleus based on results of a scattering experiment.

Explanation

Bohr proposed a planetary model of the atom to explain the emission spectrum of hydrogen. Hence option B is incorrect.

Einstein explained the observation of the photoelectric effect experiment by stating that light has particle-like properties. Hence option C is incorrect.

Schrödinger proposed that electrons have wave like nature.  Hence option D is incorrect.

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 :
