#1 When 25g of sulfuric acid (H2SO4) reacts with 25.0g sodium hydroxide (NaOH) according to the following equation, what is the expected yield of sodium sulfate (Na2SO4)

H2SO4 + 2NaOH --> Na2SO4 + 2H2O

#2)
If the actual amount of Na2SO4 produced in problem #1 is 25.0g, what is the percent yield of Na2SO4, and what substance was the limiting reagent.

Explanation:

where's the diagram?

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
