Does the potential energy of the chemical in a paper burning increase or decrease during this reaction?

Expert Solution

Answer: In a simple word decreases.

The chemical energy stored in a substance is called as potential energy of the substance. This stored chemical potential energy is the heat content or enthalpy of the substance. If the enthalpy decreases during a chemical reaction, a corresponding amount of energy must be released to the surroundings. This means exothermic reaction. burning a paper is a heat releasing process (exothermic process), hence the potential energy of the chemical in a paper burning decrease during this reaction as it goes to the surroundings.

In chemical reactions, heat is converted into chemical energy (the potential energy stored in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed. Thus, the enthalpy change for a reaction can be approximated from ΔHrxn=∑(ΔHbreaking)+∑(ΔHforming) where H represents bond energies for the breaking (positive bond energy)...

- When subcritical flow goes over a step down, does the kinetic energy increase, decrease or remain constant? - You have subcritical flow going through a channel constriction that does not influence upstream water levels. If the critical depth is observed in the constriction, the minimum specific discharge is passing through the constriction True or false? - Subcritical flow encounters a step up transition that is smaller than the maximum step height. Does the specific energy: increase decrease remain the...
