Conservation of Mass

CAVA 302 303 S1 U5 L1 Conservation of Mass

QuestionAnswer
Chemical [...] are used to describe chemical reactions. Chemical equations are used to describe chemical reactions.
In a chemical reaction, the substances you begin with are the [...]. In a chemical reaction, the substances you begin with are the reactants.
In a chemical reaction, the substances you end up with are the [...]. In a chemical reaction, the substances you end up with are the products.
In a chemical equation, the arrow always points to the [...]. In a chemical equation, the arrow always points to the products.
[...] react with each other to produce products. Reactants react with each other to produce products.
Reactants react; [...] are produced.. Reactants react; Products are produced..
Chemical equations are typically written using chemical [...]. Chemical equations are typically written using chemical symbols.
Chemical equations: Reactants are separated from each other with a [...] sign. Chemical equations: Reactants are separated from each other with a + sign.
Chemical equations: Products are separated from each other with a [...] sign. Chemical equations: Products are separated from each other with a + sign.
Chemical equations: Reactants and Products are separated from each other with an [...]. Chemical equations: Reactants and Products are separated from each other with an arrow.
Chemical equations: The arrow always points to the [...]. Chemical equations: The arrow always points to the products.
Chemical equations: If the arrow is pointing away from it, it's a [...]. Chemical equations: If the arrow is pointing away from it, it's a reactant.
Chemical equations: if the arrow is pointing toward it, it's a [...]. Chemical equations: if the arrow is pointing toward it, it's a product.
The law of conservation of mass states that the mass of the reactants in a chemical reaction is always [...] the mass of the products. The law of conservation of mass states that the mass of the reactants in a chemical reaction is always equal to the mass of the products.
Conserved' means 'protected' or '[...]' Conserved' means 'protected' or 'retained'
The law of [...] of mass says that mass is protected or retained in a chemical reaction; it doesn't change as reactants turn into products. The law of conservation of mass says that mass is protected or retained in a chemical reaction; it doesn't change as reactants turn into products.
[...] of Mass was discovered by Antoine Lavoisier in the mid-1700s. Conservation of Mass was discovered by Antoine Lavoisier in the mid-1700s.
