Chapter 2, Problem 89CP
Each of the statements below is true, but Dalton mighthave had trouble explaining some of them with his atomictheory. Give explanations for the following statements.
a. The space-filling models for ethyl alcohol anddimethyl ether are shown below.
These two compounds have the same composition bymass (52% carbon, 13% hydrogen, and 35% oxygen),yet the two have different melting points, boilingpoints, and solubilities in water.
b. Burning wood leaves an ash that is only a small fractionof the mass of the original wood.
c. Atoms can be broken down into smaller particles.
d. One sample of lithium hydride is 87.4% lithium bymass, whereas another sample of lithium hydride is74.9% lithium by mass. However, the two sampleshave the same properties.
