Question
A system is where a reaction takes place. When we discuss systems, there are two types - closed and open. A closed system prevents any of the matter from leaving the reaction, even when that matter is gas. In an open system, the matter can leave - often as heat, smoke, vapor, or even splashes/spill over.
In both types of systems, the "heat" produced by the reaction can leave and go into the surroundings.
Check out the picture below for a real life example of a closed vs. open system.
When the lid is on, the steam from the pot cannot leave the system. Any steam will roll off the lid, back down into the pot.
Without the lid, the system is open and the steam can leave. Eventually the pot may run "dry" as the water evaporates.

We want to study the conservation of mass in a real world reaction. What type of system should we use to measure the mass before and after the reaction?

To measure the mass before and after a reaction, we will need to use a closed system. Many reactions have a gas or vaporized substance that can escape into the surroundings if we do not contain it within the system. Check out the video below for how this person creates a closed system.

Based on the descriptions provided in the text, here are the answers to the questions:
1. **What type of system is this?**
- **Open**
2. **What type of system should we use to measure the mass before and after the reaction?**
- **Closed**
3. **How did this person create a closed system?**
- **They used a ziploc/sandwich bag that was sealed.**
(It's also possible that "They used a pressure cooker" could be correct if contextually relevant, but based on the question it seems they are looking for a straightforward, commonly understood method.)
If you have further questions or need additional assistance, feel free to ask!
