Identify the oxidising and reducing agents in these reactions, by looking at the gaming and loss of ovygen. a) 2Mg + O2 = 2MgO

B) Fe2O3 + 3CO = 2Fe + 3CO2

A is oxidation . B is reduction

Explanation:

A will be oxidation agent because there is gain of

electrons

B will be reducing agent because there is loss of

electrons.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

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 :
