Use enthalpies of formation to calculate the standard enthalpy of reaction for the following methane-generating reaction of the methanogenic bacteria:
4 H2(g) + CO2(g) ----> CH4(g) + 2 H2O(g)
given that you are able to perform a diffusion experiment during a period of 30 days and that you are able to analyze a
Given the following equation, how many grams of PbCO3 will dissolve when 1.5L of 1.00 M H+ is added to 6.00g of PbCO3? PbCO3(s) + 2H+(aq) = Pb^2(aq)+ +H2O (l)+ CO2(g)
