The standard enthalpy of formation of CO2(g) is -393.5 kJ mol-1 . What is the enthalpy change if 4.49 g C(s) reacts with 9.21 O2(g) to form CO2(g)

Explanation:

Hello there!

In this case, since the reaction for the formation of CO2 is:

Whereas the determination of the limiting reactant must be firstly performed as shown below:

Thus, we infer O2 is the limiting reactant because it yields less moles of CO2 in comparison to C; and therefore, the enthalpy change is:

Best regards!

lol idk man i guess u gotta ask bill nye the science guy

c. electrical charges of ionic bonds.
