The combustion analysis of toluene, a common organic solvent, forms the 0.00137g of H2O and 0.00586g of CO2. If the compound contains only hydrogen and carbon, determine the molecular formula when the molecular mass is 92g/mol.
Hydrogen gas,H2(g) and the Carbon dioxide gas, CO2 (g), are brought together in a vessel and heated to1565oC. At this temperature they react to produce the water, H2O(g) and the carbon monoxide oxide, CO(g). Explain, are the reactants or the
