As part of an investigation, students combined substances in a beaker to observe chemical reactions. They performed two procedures. They measured the mass of each substance before and after each reaction. The table shows their observations. Assuming the students did not make any careless errors, what likely explains these changes in mass?
Procedure 1: All the reactants were liquids that evaporated.
Procedure 2: A gas was formed as one product, and it escaped into the air.
Procedure 1: One of the reactants was converted to thermal energy.
Procedure 2: All the products were liquids.
Procedure 1: The reactants were liquids with different densities.
Procedure 2: The reactants were combined into only one product.
Procedure 1: One of the products was a gas that escaped into the air.
Procedure 2: A gas from the air reacted with one of the other reactants.
