Calculate the ÎHâ for this reaction using the following thermochemical data:
CH4(g)+2O2(g)â¶CO2(g)+2H2O(l) ÎHâ=â890.3kJ C2H4(g)+H2(g)â¶C2H6(g) ÎHâ=â136.3kJ 2H2(g)+O2(g)â¶2H2O(l) ÎHâ=â571.6kJ 2C2H6(g)+7O2(g)â¶4CO2(g)+6H2O(l) ÎHâ=â3120.8kJ
Express your answer to four significant figures and include the appropriate units.
Calculate the ÎHâ for this reaction using the following thermochemical data:
CH4(g)+2O2(g)â¶CO2(g)+2H2O(l) | ÎHâ=â890.3kJ |
C2H4(g)+H2(g)â¶C2H6(g) | ÎHâ=â136.3kJ |
2H2(g)+O2(g)â¶2H2O(l) | ÎHâ=â571.6kJ |
2C2H6(g)+7O2(g)â¶4CO2(g)+6H2O(l) | ÎHâ=â3120.8kJ |
Express your answer to four significant figures and include the appropriate units.
