☆☆☆☆☆The amount of heat a substance can hold.
The usable energy released or absorbed by a reaction.
Entropy is the inclination for things to increase their level of disorder.
eg. If you buy a puzzle in a box and you shake it really hard the pieces become more disorganized, near fall back into their proper place.
APEX ANSWER: Entropy measures the disorder in a system
The enthalpy of reaction does not depend on the steps taken in the reaction.(Apex)
If there is an increase in the number of gas molecules, then S > 0.
The arrangement of the atoms
All the reactions in a path are added together.
Changing the temperature
Occurring without added energy
Kinetics
Enthalpy and entropy.
Grams liquid × mol/g × Hfusion
G = 0 kJ/mol
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
A+B —> C+D+ HEAT (Apex)
The reaction produces heat.
Only one requires air molecules to generate lift.
The rocket might explode from the added pressure when the combustion reaction hits the air.
to simplify the design of the rocket.
