NaOH+H 2 CO 3 Na 2 CO 3 +H 2 O -Balance the chemical equation
-What is the mole ratio between sodium carbonate and carbonic acid?
-Find the mass of water when 3.5 moles of NaOH react
-Find the number of moles of produced when 5.7x1023 formula units of NaOH react

what is the question here. i think you messed up.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
