Seniors can learn from the younger generation to better appreciate the banal moments of the day and be more open to sharing moments, thoughts, or ideas with friends and family, no matter how trivial it might seem.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?

Radda [10]

Answer:

$329.48 KJ/mol$ heat is released by the combustion of $2 mol$ of methane

Explanation:

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).

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

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

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

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

$= -787 KJ/mol+1116.48 KJ/mol$

$=329.48 KJ/mol$

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

Why does the concentration of CO2 go up and down throughout the year?

nadezda [96]

the role of plants in carbon cycle

Explanation:

the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
