How much heat is produced when 1.25 g of chromium metal reacts with oxygen gas under standard conditions?

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

In such a way, we compute the corresponding yielded moles of chromium (III) oxide by stoichiometry:

Now, since this is about a formation reaction, the standard enthalpy of formation accounts for the released heat during this reaction, which is:

Finally, as we computed the yielded moles, we compute the associated produced heat via:

Best regards.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
