Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

law theory 3. Exercise 1.5 Part A - Define chemistry. ANSWER: Chemistry is the science that seeks to understand what matter does by studying what atoms and molecules do. Chemistry is the science of matter and its motion‚ as well as space and time - the science that deals with concepts such as force‚ energy‚ mass‚ and charge. Chemistry is the science that studies the molecular transformations only in nonliving matter. Chemistry is the science that studies the molecular transformations

Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited
