Answer:
The synthesis of aspirin is known in organic chemistry as an esterification reaction. This is a substitution reaction in which an alcohol (the –OH group in salicylic acid) reacts with acetic anhydride to form an ester, aspirin.
Explanation:
Answer:
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
B. Rock Y cooled more slowly than rock X.
Explanation:
Igneous rocks are rocks that forms from the solidification of magma either on the earth surface or beneath surface.
Those that forms on the surface are called volcanic rocks
Those that forms beneath are called plutonic rocks.
When magma forms within the surface, it cools and solidifies slowly. This will allow crystals to grow slowly. Therefore, the crystals will have a big size in the rock. The texture of the rock is now said to be coarse grained.
Those that forms on the surface cool rapidly and the minerals are fine grained. This is the case with X

answer is 2.03×10^-11 J
Answer:
335.35 grams
Explanation:
Convert grams of H2SO4 to moles and get 4.08 moles.
Using stoichiometry, the chemical equation tells us that for every mole of H2SO4, one mole of Na2SO4 is produced. This means that, theoretically, you should get 4.08 moles.
Convert moles to grams and get 335.34 g.
However, if you were to actually perform this reaction, you would get less than the theoretical value.
