In our lab we performed an experiment where we mixed baking soda and hydrochloric acid. The mass of the reactants was more than the mass of the products.. why?

Write down your reaction. One of your products is H2CO3. However, this is really dissolved CO2. There is only so much CO2 that can be dissolved in water unless you want to pressurize the solution (like in sodas). So the rest goes poof into the air and you have the result you have, since you haven't accounted for all products.

Because of chemical thermodynamics and LeChatelier's principle, the reactants are favored over the products in this reaction.

as the first answer stated- CO2 gas is released, so this is why the mass of products physically had less weight because the gas escaped.

How did you obtain the mass of the CO2(g) that was given off?
