-Chemistry is unimportant in everyday life
-Chemistry fosters understanding of phenomena at an atomic-molecular level - correct answers
Chemistry is unimportant in everyday life
How can the relationship between inorganic (general) and organic chemistry best be described? - correct
answer both branches of chemistry share the same central concerns
which statement about chemistry is INCORRECT?
-chemistry involves the study of atoms and molecules and how they react
-chemistry is involved in many everyday events
-a knowledge of chemistry can help a voter make informed decisions
-general chemistry and organic chemistry are completely different sciences - correct answers general
chemistry and organic chemistry are completely different sciences
which of the following is NOT a focus of the discipline of chemistry?
-the structure and behavior of atoms of elements
-the reactions between substances
-the composition and properties of compounds
-the motion of the planets - correct answers the motion of the planets
describe the discipline of chemistry - correct answers chemistry helps us understand the behavior of
materials at an atomic or molecular level
which of the following involves chemistry?
-automobile
-window cleaner
,-cooking
-all of the above - correct answers all of the above
how can the overlap of chemistry with biology be explained? - correct answers biological molecules
follow the same rules as other molecules, and therefore their study falls into the domains of both
biology and chemistry
which of the following is NOT influenced by chemistry?
-baking bread
-doing laundry
-changing ocean tides
-making wine - correct answers changing ocean tides
after many experiments, scientists knew that phlogiston was a substance that was eliminated from a
substance when it burned, losing weight. The concept of phlogiston was eventually rejected when it was
observed that some materials actually weighed more after they were burned. Which term in the
scientific method best describes the concept of phlogiston? - correct answers theory
In carrying out the experiment of burning paper and making observations, which of the following was
NOT a simple observation that was made about the properties involved in the experiment?
- ashes are created when you burn paper
-ashes from burnt paper cannot burn again
-ashes are gray in color
-ashes from burnt paper weigh more than the unburnt paper - correct answersashes from burnt paper
weigh more that the unburnt paper
which of the following steps is NOT a part of the scientific method?
-design experiments and conduct observations
-formulate a theory based on a single observation
, -formulate a hypothesis
-test hypothesis with an experiment - correct answersformulate a theory based on a single observation
what is the term in the scientific method that summarizes the results of repeated observations regarding
a given phenomenon without providing an explanation? - correct answerslaw
according to Dalton's atomic theory of matter, what happens during a chemical reaction? - correct
answersatoms rearrange to form new compounds
which of the following statements is NOT true about a theory?
-future observations can be used to predict a theory
-a theory is usually consistent with a reported experimental results
-a theory is a proven fact that is indisputably true
-a theory is an all-encompassing explanation for specific scientific events - correct answersa theory is a
proven fact that is indisputably true
which of the following is NOT a postulate of Dalton's atomic theory of matter?
-matter consists of indivisible atoms
-all atoms of an element are identical in mass and all other properties
-atoms can be reduced to protons, electrons, and neutrons
-different chemical elements have different kinds of atoms and different masses - correct answersatoms
can be reduced to protons, electrons, and neutrons
