Chapter 1, Problem 16QAP
Why is the ability to solve problems important in the study of chemistry? Why is it that the method used to attack a problem is as important as the answer Lo the problem itself?

what is chemistry? why is it reliable, flexible and testable?
When large pieces of a purple-black crystalline solid are gently heated, a purple vapor is formed which upon cooling deposits many tiny purple-black crystals with the same hardness, density, reflectivity, etc. as the large pieces. Did this experiment study chemical changes or physical ones? Justify your answer with reasoning.
Based on the quote below,
"We may lay it down as an incontestable axiom that, in all the operations of art and nature, nothing is created; an equal amount of matter exists both before and after the experiment. Upon this principle, the whole art of performing chemical experiments depends." --Antoine Lavoisier, 1789
Explain what the quote implies and relate it to the "Law of Conservation of Mass".

- 4 Chemistry is the science of the structure and interactions of matter. The INCORRECT alternative is: D) All living and nonliving things consist of matter, which is anything that occupies space and has mass. Mass is the amount of matter in any object, which does not change. Weight, the force of gravity acting on matter, does change. When objects are farther from Earth, the pull of gravity is strong; this is why the weight of an astronaut is close to zero in outer space. 5. Structure of Atoms: each element is made up of atoms, the smallest units of matter that retain the properties and characteristics of the element. Is CORRECT to affirm that: B) One subatomic particle composed of individual atoms. Only three types of subatomic particles are important for understanding the chemical reactions in the human body: protons, neutrons, and electrons. The dense central core of an atom is its nucleus. Within the nucleus are positively charged neutrons (p+) and uncharged (neutral) protons…arrow_forwardPART 2 Density of Gravel The mass of the empty weighing boat was measured. Then the weighing boat was filled with gravel, and the mass of the weighing boat and the gravel was measured. Mass of weighing boat = 0.98 g Mass of weighing boat and gravel = 58.98 g We are interested in the mass of the gravel. (a) Gravel is matter. Why? (b) What is the name of this method of measurement of mass of a substance? (c) What is the other method of measurement of mass of a substance?
