The mixture of the hydrocarbon and oxygen is sparked so that a complete combustion reaction occurs, producing CO2(g) and H2O(g). The partial pressures of these gases at 127°C are 0.600 atm for CO2(g) and 0.800 atm for H2O(g). There is O2(g) remaining in the container after the reaction is complete.The mixture of the hydrocarbon and oxygen is sparked so that a complete combustion reaction occurs, producing CO2(g) and H2O(g).

In this experiment, the final pressure in the container was 1.04 atm, which was the same final pressure as in the first experiment. (a) Calculate the number of moles of CO2(g) present in the container after 20 minutes of heating. PV = nRT PV = n = (1.04 atm)(1.00 L) RT (0.0821 L atm )(1100 K) = 0.0115 mol CO 2.balanced equation with the correct proportions among reactants and products. (e) Calculate the mass of the hydrocarbon that was combusted. mass = (number of moles)(molar mass) = (6.09 10 3 mol)(44.1 g/mol) = 0.269 g. point is earned for using the number of moles combusted from part (a).…

Electron flow should be indicated only in a counter-clockwise direction in the external circuit, from the Cl2 anode to the Mg cathode. (b) For the correct answer and calculated value: No, because 2.0 V is less than 3.73 V, which is the minimum voltage needed for electrolysis to occur.in the presence of hydronium ions. A proposed mechanism for the reaction consists of the three elementary steps shown below. Step 1: CH3OH + CO → HCO2CH3 Step 2: HCO2CH3 + NH3 → HCONH2 + CH3OH Step 3: HCONH2 + H3O+ → HCOOH + NH4 +. slow fast. fast. Overall reaction: CO + NH3 + H3O+.
For example, students would use a q value from trial 2 but a mole calculation from trial 1. Using the formula from the exam, Cp = H/ T, rearranging that formula to H = Cp ∙ T and then calculating H.
