... Conservation of mass derives from the postulate that atoms are not destroyed in chemical reactions. The Law of Definite Proportions derives from the notion that compounds are always composed of the same types and numbers of atoms of the various elements in the compound. ...

Reactions and Equations
... When writing out chemical equations, it is important to know which elements form diatomic molecules. There are seven elements that form diatomic molecules. The seven diatomic elements are: ...

Lecture I
... When a system is at equilibrium, its state is defined entirely by the state variables, and not by the history of the system. The properties of the system can be described by an equation of state which specifies the relationship between these variables. ...

Balancing Equations
... How many….on the reactants side? On the products side Fe Fe O O The iron is not balanced to conserve mass. We have 1 on the left and 2 on the right, so we need to at a coefficient (small whole number that are placed in front of the formulas in an equation in order to balance it). So the equation wou ...
