Solution Summary: The author defines a chemical change as the change in which substances are converted into new substances having different compositions and properties.
Match the key terms with the following descriptions.
(a) �le smallest particle of an element that retains �le characteristic chemical properties of that element a change in which substances are converted into new substances that have compositions and properties different from those of the original
(b) substances
(c) anything that occupies space and is perceptible to the senses
(d) a substance composed of two or more elements combined in de�nite proportions
(e) a combination of atoms of one or more elements
(f) a process Characterized by Changes only in �le physical properties of a substance not in its composition
(g) the physical state in which matter has no �xed shape or volume but expands to �ll its container completely
(h) �le energy possessed by an object because of its position
(i) a tentative explanation for the properties or behaviour of matter that accounts for a set of observations and can be tested
(j) the energy possessed by an object because of its motion
Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Which elements have molecules as their basic units?(a) helium (b) oxygen(c) iron (d) bromine
Solve the given problem using an element that has three naturally occurring isotopes.
Click on the site (http://openstaxcollege.org/l/16PhetAtomMass) and select the “Mix Isotopes” tab, hide the “Percent Composition” and “Average Atomic Mass” boxes, and then select the element boron.(a) Write the symbols of the isotopes of boron that are shown as naturally occurring in significant amounts.(b) Predict the relative amounts (percentages) of these boron isotopes found in nature. Explain the reasoning behind your choice.(c) Add isotopes to the black box to make a mixture that matches your prediction in (b). You may drag isotopes from their bins or click on “More” and then move the sliders to the appropriate amounts.(d) Reveal the “Percent Composition” and “Average Atomic Mass” boxes. How well does your mixture match with your prediction? If necessary, adjust the isotope amounts to match your prediction.(e) Select “Nature’s” mix of isotopes and compare it to your prediction. How well does…
In a series of experiments, a chemist prepared three differentcompounds that contain only iodine and fluorine and determinedthe mass of each element in each compound:
Compound Mass of Iodine (g) Mass of Fluorine (g)1 4.75 3.562 7.64 3.433 9.41 9.86(a) Calculate the mass of fluorine per gram of iodine in eachcompound. (b) How do the numbers in part (a) support theatomic theory?
