What type of energy is associated with food? How is that energy stored? How does food energy change when it is used to do work?
AVprozaik [17]
The energy associated with food is chemical energy.

The food contain carbohydrates, proteins, vitamins and minerals, that are used by chemical reactions in the live organisms (the metabolism) to build the cells that form our tissues (muscles, bones, blood).

The chemical energy is stored as chemical bonds in the cells and is released when the bonds break giving energy that we use to run about, and move and talk (kinetic and sound energy).

How much heat is absorbed when 2.8 mol nh4no3 is dissolved in water? the heat of solution of nh4no3 is 25.4 kj/mol.
Kay [80]

The heat absorbed when 2.8 mol NH₄NO₃  is dissolved in water is 71.96 kJ.

<h3>What is heat?</h3>

Heat is the transportation of energy to or from a thermodynamic system.

By the formula of heat

\rm (n) \times (delta\;Hrxn) = (qrxn)

Where n = moles

Delta Hrxn is molar heat

q = heat

Putting the values in the equation

\rm qrxn = (2.8 mol) \times(25.7 kJ/mol) = 71.96 kJ

Thus, the heat absorbed when 2.8 mol NH₄NO₃  is dissolved in water is 71.96 kJ.
