Question

PLEASE, i need so much help. Do this one thing for me please. It's enthalpy, 3 parts. It's so fast just please...

The following reaction occurs under standard conditions:

CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)

a. Which bonds are broken and which are formed during the reaction? (1 point)













b. Determine the enthalpy of the reaction. (2 points)













c. Is the reaction endothermic or exothermic? Explain. (1 point)

Answer 1

Answer:

A and C

Explanation:

I can help you with A and C but I don't have the enthalpy calculation handy to perform the calculation.

A.  You are breaking the Carbon-Hydrogen bonds in methane CH4 and the Oxygen-Oxygen bond.  You are forming bonds between Carbon and Oxygen to form CO2 and you are forming bonds between Hydrogen and Oxygen to form water.

B. skipped

C. The reaction is exothermic.  The reaction is burning methane in oxygen.  This reaction will give off heat which is the definition of exothermic.
