Magnesium (Mg) emits two very closely spaced lines in the green at 617 nm and 618 nm. A) Which of the two lines is associated with large energy photon? ____nm B) Which of the two lines has a larger frequency? ____nm
Use average bond energies to estimate enthalpy changes for C(s) + CO2(g) -----> 2CO(g) i got -221 kj/mol, but it was the wrong answer though.
The enthalpy change for any reaction can be obtained by subtracting the sum of the enthalpy changes of formation of the reactants from the sum of the enthalpy changes of formation of the products.
Question- Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxi..
Calculate the standard enthalpy change for this reaction using enthalpies of formation.
