Why do you think the enthalpy of activation, H ‡ , for a syn-periplanar elimination is higher than that for an anti-periplanar elimination?
Considering the given equation 4 C3H5N3O9---> 6 N2+ 12 CO2 + 10 H2O + O2,This reaction generates many gaseous products and a large amount of heat determine what is the maximum amount of Oxygen.

A mixture of sand and iron pieces weighs 53.29 g. Using a magnet, the iron is removed and weighs 15.63 g. What is the percent composition of sand in the mixture?
Solid aluminum reacts with aq H2 SO4 to form H2 gas and aluminum sulfate. when a sample of Al reacts, 425 mL of H2 gas is produced at 24 degree celsius at a press of 744 mmHg. How man grams of Al reacted?
In lab we are doing chemical kinetics. We started off with 0.7550 M of Oxalic acid and then added water and 0.1300 M of Permanganate. For the first trial, 5 mL of Oxalic acid was used, then 6 mL of water were added and then 1 mL of Permanganate we..
