The explosive nitroglycerin (c3h5n3o9) decomposes rapidly upon ignition or sudden impact according to the following balanced equation: 4 c3h5n3o9 (l) → 12 co2 (g) + 10 h2o (g) + 6 n2 (g) + o2 (g) δrxnho = −5678 kj calculate the standard enthalpy of formation (δfho) for nitroglycerin. the enthalpy of formation of co2 (g) is -393.5 kj/mol. the enthalpy of formation of h2o (g) is -241.8 kj/mol.

The for in the reaction is -365.5 kJ/mol.

Explanation:

Enthalpy change of a reaction is defined as the difference in enthalpy of all the products and the reactants each multiplied with their respective number of moles. The equation that is used to calculate the enthalpy change of a reaction is:

For the given chemical reaction:

The equation for the enthalpy change of the above reaction is:

We are given:

Putting values in above equation, we get:

Hence, the for in the reaction is -365.5 kJ/mol.

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.

what are the choices?
