| Question | Answer |
|---|---|
| What is an inorganic nomendature | charges of main group monatomic ions -chlorine gass -petrie dish base |
| How many number of electrons for each cateyon and anion | take away electron for cateyion add election for anion |
| What is a Polyatomic ion | One or more ions composed of more then one atom ends in ate-more lite-less |
| What is an ion | atoms opr compounds with a charge |
| What is a monatomic ion | single atom with positive or negative from loose or gain of one or more electrons |
| What is a momoatmic anion | for naming ions add suffix "ide" using roman numerals for ion charges |
| What is a molecule | two or more atoms connected together so strongly that they behave as single particle |
| What is a diatomic | 2 atoms of this element in molecule |
| What are the is acraynom for diatomic atoms | BrINCLHOF( "BrinkleHoff) Br=Bromine I= Iodine F=Flourine N=Nitrogen Cl= Clorine H=Hydrogen 0=Oxygen |
| What is a chemical bond | the connection between two atoms |
| What is a chemical nomenclature | 1. identify the element in the molecule form 2. begin name with element first, Pre, Suf 3. name second element using three pieces 4. combine words leave space between |
| What is aqueous | word described sometimes in water H20 = ends in ate |
| What is a acid compound | Which one or more H+ ions are bonded to a negative ion HCL > H+ , No oxygen |
| What is the ryeme to remember how to name ions? | My rIDE has HYDROLICs I ATE something ICky sprITE is deliciOUS |
| What is a chemical change | transformation of one moleculor substnace into another ex; gas burns > react with ocygen in air> boom |
| What is a chemical reaction | some involve heat light, others involve gasses and color changes, converting compounds expresses a chemical change process of bonding substances together a process that leads to filled valence shells a process that releases or consumes energy |
| What is a chemical equation and how to solve | same number of atoms in each element in the reactants must be the same as the number of atoms of each elements in products solve: change number of moleces that reaction are produced |
| What are reactants | the left side of a chemical equation |
| What are products | right side of chemical equation |
| What is a coefficent | the number in front of the chemical equation indication the balance of the number of electrons |
| What is a balanced equation | when reactants and products of a chemical equation have the same number of atoms of all atoms present |
| What are the 5 types of chemical reactions | 1. single displacement reaction 2. double displacement reaction 3. composition 4. decomposition 5. combustion reaction |
| What is a single displacement reaction | chemical reaction in which one element substituted for another element in a compound, generating a new element and a new compound as products |
| What elements will not product a single displacement reaction | halogens: Florine, Clorine, bromine, iodine unless you have activity series. If a element is higher on the table in the chem eq. then it will not produced |
| What is a double replacement reaction | when two parts of a ionic compounds are exchanged, making two new compounds |
| What is a precpitation reaction | tow ionic compounds are dissolved in which form a new ionic compound that does not dissolve |
| What is a solid precipate: | driving force that makes the reaction proceed |
| What are the solubility rules | general statements that predict which ionic compounds dissolve(are soluble) and which do not (are not soluble or insoluble) |
| What is a combustion reaction | aka combined or synthesis reaction: produces a single substance from multiple reactants |
| What is a decomposition reaction | starts from single that is it decomposes |
| What is a combustion reaction | occurs when a reactant combines with oxygen many with atmosphere oxides of all elements as products |
| The official scientific name for water, H2O is ____. | hydrogen (II) oxide |
| Name the compound with chemical formula of BrO3. | Bromine trioxide |
| When a salt is dissolved in water, it is represented by the following notation in a chemical reaction? | (aq) |
| A 15.0 g sample of a white, solid substance, is heated in the presence of air. The solid remaining after heating has a mass of 12.6 g. The reaction that took place must have been a/an ________ | decomposition reaction |
| What object can undergo both physical and chemical changes. | burning candle |
| Can the subscripts in a chemical reaction be changed? | No, they define the molecules in the reaction |
| What are the different reactants and products for type of chemical reaction | synthesis; A + B -> AB Decompostion: AB -> A + B Combustion (xhy)(O2) + O2 -> CO2 + H2O Single replacement: A + BC -> B + AC Double replacement: AB +CD -> AD + BC |
