What two gasses were made by electrocuting water?
Oxygen and Hydrogen
If there are 15 atoms of oxygen and 30 atoms of hydrogen in a in a closed system before a chemical reaction, how many of each will be present after the chemical reaction takes place?
Bonus 100: What new substance/molecules can be made from the chemical reaction?
15 oxygen, 30 hydrogen. Water.
A measurement that involves somethings mass and volume (I.e. how much mass 1 mL of something has)
Density
True or false: when we heated water, it made a new substance.
False. The properties of the liquid after heating were the same properties as water. Because the properties are the same, they must be the same thing.
True or false: new atoms can be made during chemical reactions.
False. New molecules/substances CAN be made, but new atoms CANNOT be made. The number and type of atoms is always equal before and after chemical reactions.
If two containers filled with gas have the same properties, they will be the same __________
Substance or Molecules
