CHEM 201 Lecture 12: CHEM 201 - Lecture 12
Document Summary
Acid-base (neutralization) precipitation reactions gas-formation reactions reactions reactions between two compounds in water solutions in which the cations and anions. Change partners to form two new compounds ax+by ay+bx. 2mg + f2 2mgf2 2h2o 2h2 + o2 less act. Chemical equation is a shorthand description of a chemical reaction, using symbols and formulas to represent the elements and compounds involved. Above the arrow: t0, - it is necessary to heat, p under the high pressure, cat presence of catalyst. Calcium oxide reacts with carbon dioxide to produce calcium carbonate to yield to form. Under the law of conservation of mass all chemical reactions must be balanced. A balanced chemical equation must always include the same number of each kind of atom on both sides of the equation. Coefficients indicate the amount of each compound or element present and can be changed to balance the equation. Ch4 + 2o2 co2 + 2 h2o.
