How do chemical equations represent conservation of mass?

Answer 1

Ellie Andrews

Reactants are the #"garbage in"#, and products are the #"garbage out."#

Additionally, the chemical (and physical) change can be symbolically represented by chemical equations:

#"Reactants "rarr" Products"#

Additionally, the conservation of mass and the conservation of electric charge characterize all chemical change.

Chemical equations represent the conservation of mass by ensuring that the total mass of the reactants is equal to the total mass of the products. This principle is expressed through balancing chemical equations, where the number of atoms of each element is the same on both sides of the equation. This balancing ensures that no atoms are lost or gained during the chemical reaction, thus conserving mass.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
