In the “Liquid Oxygen” article, you read about how liquid oxygen is made and how it is needed to fuel rockets. The Universal Space Agency is planning to use liquid oxygen to fuel a rocket, carrying a new surface lander, to Titan.

The liquid oxygen machine is producing less liquid oxygen than normal. You have been asked to determine what is causing this problem.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
