The reaction CH3NC ? CH3CN is called an isomerization reaction andinvolves the breaking of a C–N bond and subsequent formation of a C–C bond—the reactant andproduct have the same molecular formulas and so are isomers. This reaction has a rate constant of0.46 s–1 at a specific temperature. What is the concentration of CH3NC after 0.20 min if its initialconcentration is 0.10 M?A. 4.0 × 10–4 M B. 7.6 × 10–6 M C. 8.5 × 10–2 MD. 9.1 × 10–2 M E. 2.5 × 10–2 M

What information does a complete ionic equation give that the balanced equation doesn’t show?

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
