CLASS 48 3 º A: REVIEW OF DEVELOPMENT, CHEMICAL REACTIONS

Hello everyone


In today's class we review formulation.

addition we

widely across the theory of chemical reactions:

Law of conservation of mass

"In every chemical reaction mass is conserved , ie the total mass of reactants equals the total mass of the products

Adjusting chemical reactions
Steps necessary to write a reaction set:

1) It determines which are the reactants and products.

2) write an equation is not adjusted using the formulas of the reactants and products.
3) the reaction is adjusted by determining the coefficients that give us equal numbers of each type of atom on each side of the arrow of reaction, usually whole numbers.
