See generally Laura W. Morgan, Child Support Guidelines: Interpretation and Application Â§ 4.05 (Supp. 1999). Many states rewrote their emancipation statutes in the 1970s and 1980s to provide that a parent is released from a child support obligation when the child is 19 or graduates from high school. [See Table below.] Emancipation may also come before the age or event stated in the above Table.
The Law of Conservation of Mass (or Matter) in a chemical reaction can be stated thus: In a chemical reaction, matter is neither created nor destroyed. It was discovered by Antoine Laurent Lavoisier (1743-94) [15K GIF] about 1785.
Aa Aa Aa. The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.he atom itself is neither created nor destroyed but cycles among chemical compounds. Ecologists can apply the law of conservation of mass to the analysis of elemental cycles by conducting a mass balance. These analyses are as important to the progress of ecology as Lavoisier's findings were to chemistry.
