10g of white powder reacts with 10g of clear liquid. The reaction bubbles and changes color producing a black liquid that has a mass of 13g. What can be concluded?

• 5g of gas was produced
• This experiment violates the conservation of mass
• 7g of gas was produced
• The excess reactant is destroyed & disappears during the reaction
