Question

question 17 (5 points) listen stoichiometry is based on a) conservation of matter. b) pressure. c) temperature. d) molecular weight.

Explanation:

Stoichiometry deals with the quantitative relationships in chemical reactions. The law of conservation of matter (mass) states that matter is neither created nor destroyed in a chemical reaction, which is the foundation for stoichiometric calculations (balancing equations, relating reactants and products). Pressure (B) and temperature (C) relate more to gas laws or reaction conditions, not the basis of stoichiometry. Molecular weight (D) is used in stoichiometric calculations but is not the underlying principle; the principle is conservation of matter.

Answer:

A) conservation of matter
