7. sep use models you run an experiment in which two substances chemically react in a closed system. you run the same experiment in an open system. how would the masses of the products in each experiment compare? explain.

Answer

Brief Explanations:

In a closed - system, mass is conserved according to the law of conservation of mass. All reactant atoms remain within the system and contribute to the mass of the products. In an open - system, if the reaction produces a gas, the gas can escape, reducing the measured mass of the products. So, the mass of products in the closed - system will be greater or equal to the mass of products in the open - system.

Answer:

The mass of the products in the closed - system will be greater than or equal to the mass of the products in the open - system. This is because in an open - system, some of the products (such as gases) may escape, while in a closed - system, all the reactant mass is accounted for in the products due to the law of conservation of mass.
