The dissociation of sulfurous acid (h2so3) in aqueous solution occurs as follows:
h2so3 > h+ + hso3-
hso3- > h+ + so32-
if .50 moles of sulfurous acid are dissolved to form a 1 l solution, which of the following concentrations will be least at equilibrium?

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
according to the law of conservation of mass, what is the same on both sides of a balanced chemical equation?
a. the volume of the substances
b. the subscripts
c. the total mass of atoms
d. the coefficients
a balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.
consider the balanced equation for the combustion of methane.
all balanced chemical equations must have the same number of each type of atom on both sides of the arrow.
in this equation, we have 1
atoms, and 4
atoms on each side of the arrow.
the number of atoms does not change, so the total mass of all the atoms is the same before and after the reaction. mass is conserved.
here is a video that discusses the importance of balancing a chemical equation.
