help no idea enthalpy change ???
1) What is the enthalpy change (DH) for the following reaction?
C(s) + ½ O2 (g) → CO (g)
Given the following information:
C(s) + O2 (g) → CO2(g) DH = -393.5 kJ
CO (g) + ½ O2 (g) → CO2(g) DH = -283.0 kJ
2) a) What is the percent by volume (% v/v) of a solution made by mixing 18 ml of ethanol (C2H5OH) with 42 ml of water?
C(s) + ½ O2 (g) → CO (g)
Given the following information:
C(s) + O2 (g) → CO2(g) DH = -393.5 kJ
CO (g) + ½ O2 (g) → CO2(g) DH = -283.0 kJ
