Is the set of rules that make it possible to name and represent compounds in a uniform way, Chemical Formula, Chemical Nomenclature, Common Name, Formula, What is the Formula for “Hydrochloric Acid”, C2H5OH, HCl, Write the formula of the following compound: Fe2O3, Carbon Dioxide, Triiron Monoxide, Ferrous Oxide, Diiron Trioxide, Is the organization responsible for establishing standards in chemistry:, IUPAC, ONU, ICCA, American Chemical Society, System used for ionic compounds; Roman numerals are included to indicate the oxidation number of the metallic ions., Systematic, Classic or Traditional, Stock, Chemical, Which system of nomenclature uses Greek prefixes (such as mono-, di-, tri-) to specify the number of atoms in covalent compounds?, Stock system, Systematic nomenclature, Traditional nomenclature, Common naming system, What is the chemical formula for sodium chloride?, HCl, NaCl, NaOH, In the Stock system of nomenclature, what do the Roman numerals placed in parentheses after the metallic ion indicate?, The total number of atoms, The oxidation number of the metal, The atomic mass of the element, The period number on the periodic table, What is the correct name for the compound CO2?, Carbon monoxide, Carbon dioxide, Dicarbon oxide, Carbon carbonate, Which type of nomenclature relies on historical or trivial names that do not follow standard systematic rules (e.g., water for H2O), Systematic nomenclature, Stock system, Common name, IUPAC formula, What are oxidation states?, )They are known as numbers that show how many electrons an atom gained or lost when it forms a compound., They are known as the electrons present in the atom, They are known as ions that are only positive, What is the oxidation state of sulfur in H2SO4?, -2, +3, +6, What is the oxidation state of nitrogen in NH3?, -3, +3, -1, What is the oxidation state of chlorine in the following formula: HClO3-, +5, -5, -10, What is the oxidation state of manganese in the following formula: KMnO4-, -7, +7, -3, What is the oxidation number of an element when it appears by itself?, 1, 2, 0, What is the correct formula of aluminum oxide if Al has a valency of 3 and O has a valency of 2?, AL2O3, AlO, AlO3, What is the valency of oxygen in MgO, -1, +2, -3, What is the oxidation number of nitrogen in nitric acid (HNO³), +3, +5, -7, None, What is the oxidation number of sulfur in sulphuric acid (H²SO⁴), -4, +6, +8, None, How are ions classified?, cations and anions, protons and electrons, metals and nonmetals, If you remove one electron from a neutral atom, what type of ion do you get?, anion, cation, isotope, Which particle is responsible for the positive charge in the nucleus?, electron, proton, neutron, What determines if an ion is positive or negative?, atomic mass, number of shells, Difference between protons and neutrons, why does the classification of ions into cations and anions depend exclusively on electron transfer and not on proton transfer?, Because electrons are in the nucleus, Because protons determine the element identity and remain fixed in the nucleus, Because neutrons create the charge, What happens when a neutral atom gains one or more electrons?, It becomes a cation with a positive charge, It becomes an anion with a negative charge, Its atomic number increases, What electrical charge does a cation carry?, Positive, Negative, Neutral, Which subatomic particle is lost or gained when an atom forms an ion?, Proton, Neutron, Electron, If a neutral fluorine atom (F) gains 1 electron, what is the charge of the resulting fluoride ion (F−F−)?, +1+1, b) −1−1, Why do metals generally tend to form cations during chemical reactions?, They tend to lose valence electrons to achieve a stable outer shell, They gain protons from nonmetals, They lose neutrons to reduce their atomic mass, What is the common name of the compound NaCl?, Table salt, Sodium bicarbonate, Milk of magnesia, Hydrogen peroxide, In the formula of an ionic compound, which ion is written first?, The anion, The cation, The polyatomic ion always, The most electronegative element, When naming a compound according to IUPAC rules, which part is mentioned first?, The cation, The anion, The subscript, The charge of the metal, What is the net overall charge of any neutral chemical compound?, +1, -1, 0, It depends on the number of atoms, If potassium (K+) combines with bromide (Br-), what is the resulting chemical formula?, K2Br, KBr2, KBr, K2Br2, What is the correct name for the compound KBr?, Potassium bromate, Potassium bromide, Bromine potassium, Potassium monoxide, When combining Ca2+ with S2-, what is the formula of the resulting compound?, Ca2S2, CaS22, Ca2S, CaS, What is the name of the compound CaS?, Calcium sulfite, Calcium sulfate, Calcium sulfide, Sulfur calcium, When the beryllium cation (Be2+) combines with the nitride anion (N3-), what is the correct chemical formula?, BeN, Be2N3, Be3N2, Be6N6, What is the total sum of positive charges in the compound Be3N2 if beryllium has a 2+ charge?, +3, +4, +6, +2, When polyatomic ions are combined and require a subscript greater than 1, how must they be written in the formula?, In quotation marks, In parentheses, In capital letters, Separated by a hyphen, What is the formula for magnesium arsenate formed by Mg2+ and (AsO4)3-?, MgAsO4, Mg3AsO4, Mg3(AsO4)2, Mg2(AsO4)3, What is the name of the chemical compound (NH4)2Cr2O7?, Ammonium chromate, Ammonium dichromate, Chromium nitrate, Ammonium hydroxide, In the formula Al(OH)3, which polyatomic anion is present?, Al3+, O2-, OH-, H+, What is the chemical formula for lithium hypochlorite (Li+ and ClO-)?, LiClO, Li(ClO)2, Li2ClO, LiClO2
