4. This applies to predictions of future events, to physical measurements that are already made, or to the unknown. Uncertainty arises in partially observable and/or stochastic environments, as well as due to ignorance and/or indolence.
8. It is the analysis of the relationships between different physical quantities by identifying their fundamental dimensions (such as length, mass, time, and electric charge) and units of measure (such as miles vs. kilometers, or pounds vs. kilograms vs. grams) and tracking these dimensions as calculations or comparisons are performed.
12. A ____________ is a substance or compound that is added to a system in order to bring about a chemical reaction, or added to see if a reaction occurs.
15. ____________ is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself.
17. _______________ are the species formed from chemical reactions.
18. This is the quantity of three-dimensional space enclosed by some closed boundary, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.
19. ____________ is based on, concerned with, or verifiable by observation or experience rather than theory or pure logic.
21. These are those digits that carry meaning contributing to its precision.
23. The person the mole is named after.
24. This is a clear, colorless, highly pungent solution of hydrogen chloride in water. It is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid.
25. ___________ is a group of chemical elements with similar properties: under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
28. It is the calculation of relative quantities of reactants and products in chemical reactions.
32. This is the very dense region consisting of protons and neutrons at the center of an atom.
35. The thing we use to measure small things.
36. _________ table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number (number of protons in the nucleus), electron configurations, and recurring chemical properties.
38. It is the smallest unit that defines the chemical elements and their isotopes.
40. This is a subatomic particle with a negative elementary electric charge.
41. _________ mass (M) is a physical property. It is defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance. The base SI unit is kg/mol. However, for historical reasons, are almost always expressed in g/mol.

1. It is a chemical element. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element and oxidizing agent that readily forms compounds (notably oxides) with most elements.
2. ___________ is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance(s) present in a sample.
3. The _________ metals are a group (column) in the periodic table that take a +1 charge (+1 oxidation state.)
5. It is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.
6. Name this(HNO3).
7. It is a subatomic particle with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron.
9. The international system of units, abbreviated __________, from French: Le Système International d'Unités) is the modern form of the metric system and is the world's most widely used system of measurement, used in both everyday commerce and science.
10. ____________ molecules are molecules composed of only two atoms.
11. It is the degree of closeness of measurements of a quantity to that quantity's actual (true) value.
13. Percent __________ is a special case of the percentage form of relative change calculated from the absolute change between the experimental (measured) and theoretical (accepted) values, and dividing by the theoretical (accepted) value.
14. One mole of an ideal gas has a volume of 22.7 L at _______.
16. What you have when two or more of any elements are joined together chemically.
20. This is the degree to which repeated measurements under unchanged conditions show the same results.
22. The _______ bond is type of chemical bond that involves the electrostatic attraction between oppositely charged ions.
26. In chemistry,__________ , also referred to as reaction __________, is the amount of product obtained in a chemical reaction.
27. ___________ weight(GFM) refers to the mass of a molecule. It is calculated as the sum of the mass of each constituent atom multiplied by the number of atoms of that element.
29. It is found at group 11 period 4.
30. He theorized that atoms have their charge Rutherford concentrated in a very small nucleus.

33. ____________ is a polyatomic anion with the empirical formula SO4(2−).
34. The __________ bond is a chemical bond that involves the sharing of electron pairs between atoms.
37. __________ reaction is a process that leads to the transformation of one set of chemical substances to another.
39. The law of conservation of ________ , or principle of _______ conservation, states that for any system closed to all transfers of matter and energy (both of which have _______), the _______ of the system must remain constant over time, as system _______ cannot change quantity if it is not added or removed.
