During a recent winter month in sheboygan, wisconsin, it was neccessary to obtain 3500 kwh of heat providd by a natural gas furnace with 98 % efficiency to keep a small house warm (the effiiency of a gas furnace is the percent of the heat produced by combution that is transferred into the house).
(c) what mass of carbon dioxide is produced b combustion of the methane used to heat the house?

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
