1) Write the balanced incomplete combustion reaction for ethane (C2H6), producing CO and water vapour. Make sure to include phases. Also, make sure that the stoichiometric coefficients are whole numbers and are not fractions.
a) What is the enthalpy of the reaction (ΔH°rxn), in kJ, for the process in part (d)?
b) Calculate the total heat (q), in kJ, produced by 260.0 g of ethane when 9.00% by mass of it burns incompletely and the remainder burns completely.
2.0 L of gas A at 1.0 atm and 1.0 L of gas b at 1.0 atm are combined in a 3 L flask. The flask is sealed and over time they react to completely to give gas C according to 2A(g) + B(g)= C(g)
Explain what is the relationship between standard free energy, the value of the equilibrium constant, K and the product or reactant favorability at equilibrium.
Iron is extracted from its ore using carbon. This can be represented using the following equation. Calculate the percent atom economy for pure iron.
the heat of fusion of a compound is 126 joules per gram. What is the total number of joules of heat that must be absorbed by 15.0- grams sample to change he compound from solid to liquid at its melting point?
Consider the following equalibrium: 4NH3(g) + 3O2(g) 2N2(g) + 6H2O(g). Suppose 0.30 mol of NH3 and 0.40 mol of oxygen are added to a 5.0-l container. If x mol of water is present at equalibrium, how many moles of ammonia will remain at equalibri..
