Law of Conservation and mass
by David Barnes, Jarryd Karr, and Aaron Robledo.
Explanation of the Law of Conservation of mass/matter
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation of a reactant
a substance that participates in a chemical reaction, a substance that is present at the start of the reaction
- Example- H2 and O2 are reactants in the reaction H2(g) + 1/2 O2(g) → H2O(l).
Explanation of a product
A product is a substance that is formed as the result of a chemical reaction
- Example- AgCl (s) is the product of the reaction Ag+(aq) + Cl- (aq) → AgCl
Explanation of synthesis reaction
A synthesis reaction or direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds. The product is always a compound.
- Example- Synthesis of Water 2 H2(g) + O2(g) → 2 H2O(g)
