Explanation:
You see, we must cast our minds back to Charles' law. Charles' law gives the relationship between the volume of a gas and temperature of the gas.
Now, Micheal left the balloon outside at a particular temperature and volume the previous night. Overnight, the temperature dropped significantly and so must the volume of the gas in the balloon!
Remember that Charles' law states that, the volume of a given mass of gas is directly proportional to its absolute temperature at constant pressure. Since the pressure was held constant, the drop in the volume of gas in the balloon can be accounted for by the drop in temperature overnight.

- Chemical reactions occur when compounds or elements combine to form new compounds or other elements.
- Chemical reactions may be classified into various types which include synthesis reactions, replacement reaction, decomposition reactions, and precipitation reactions among others.
- In our case, we were supposed to identify a synthesis reaction.
- Thus, we need to know what is a synthesis reaction.
- A synthesis reaction is a reaction that occurs when two elements or small compounds combine to generate a large compound.
- In this case, B is the choice that shows a synthesis reaction where hydrogen gas combines with oxygen gas to yield water.
Pretty much, if I were going to separate small solid particles, I could use like a piece of paper. I used some type of piece of paper when I was trying to separate some particles during science.
