Why is adding NaHCO3 to the aspirin crystals a chemical change?

Because carbonic acid (first pKa about 6.4) is a weaker acid than acetylsalicylic acid (pKa about 3.4) is.
Note that this answer, while technically "correct", is only going to embarrass you in class unless you know enough chemistry to explain it, which probably means you know enough chemistry to have answered it for yourself in the first place. Especially since the question doesn't actually mention carbonic acid; you've got to read between the lines a little to see why that's relevant.

What is a chemical change of baking soda?
One chemical change of baking soda is adding vinegar to it. You know, the old volcano experiment. I think you mean the chemical formula? In that case, it's NaHCO3. Otherwise, you make no sense.
If you add anhydrous sulphate to water do you get a chemical reaction?
yes you do. this is because the anyhdrate was white (crystals) and after adding water, it turned blue
What household chemical is used to raise pH in swimming pools?
By adding baking soda, you can raise the pool's pH. Baking soda, or sodium bicarbonate (NaHCO3) is a base, which neutralizes acidity.
What is silica garden?
A chemical garden is an experiment in chemistry normally performed by adding solid metal salts such as copper sulfate or cobalt(II) chloride to an aqueous solution of sodium silicate (otherwise known as water glass). This results in growth of plant like forms in minutes to hours.[1] [2] [3] The chemical garden was first observed and described by Johann Rudolf Glauber in 1646.[4] In its original form, the chemical garden involved the introduction of ferrous chloride (FeCl2) crystals into a solution of potassium silicate (K2SiO3).Common salts used in a chemical gardenAluminum potassium sulfate crystals - WhiteCopper(II) sulfate crystals - BlueChromium(III) chloride crystals - GreenNickel(II) sulfate crystals - GreenIron(II) sulfate crystals - GreenIron(III) chloride crystals - OrangeCobalt(II) chloride crystals - Purple
Why would doctors recommend buffeting aspirin especially for those with a sensitive stomach?
The term is BUFFERED aspirin. Aspirin is an acid, and can cause stomach upset. Adding another substance to aspirin (a buffering material) can help counter the acid of the aspirin- and no tricky tummy.
