How is enthalpy used to predict whether a reaction is endothermic or exothermic?
Radda [10]

<u>Answer:</u>

<em>329.48 KJ/mol heat is released by the combustion of 2 molof methane</em>

<u>Explanation:</u>

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)

\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]

                            =2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]

                            = -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]

                           = -787 KJ/mol+1116.48 KJ/mol

                                          =329.48 KJ/mol

<em>In this question, </em><em>the enthalpy of formation</em><em> has positive value and hence the </em><em>reaction is endothermic</em><em> in which the heat is released. </em>

4After completing their study of the carbon cycle, three students wrote statements making claims related to this topic. Read eac
mario62 [17]

Answer:

Incorrects:

Claim 1: When forests are cleared, we take away an opportunity to remove carbon from the atmosphere.

Claim 2: Carbon moves through biological systems and returns to the atmosphere through photosynthesis.

Claim 3: The amount of carbon involved in rapid cycling is much less than 1 percent of the total amount of carbon on Earth.

Explanation:

  • The carbon contained in forest products makes a small and manageable contribution to the global carbon balance.  Globally, the net effect on atmospheric concentration is negligible, unless the rate of decomposition in geographically displaced product stocks is different from that in the forest ecosystem from which it was removed. However, controlling these rates through proper management can lead to some degree of mitigation of increases in atmospheric CO2.
  • During the carbon cycle, animals and plants release carbon dioxide into the atmosphere through cellular respiration, and plants capture carbon dioxide through photosynthesis.
  • The amount of carbon involved in rapid cycling it is the largest since it includes the carbon exchange between living beings, and is intertwined with the carbon cycle through long-term geological processes
