Avogadro changeless: The amount of particles in 1 mole of any substance. 1 mole ≡ 6.02 × 1023 particles ________________________________________ Isotopes Isotopes: Atoms that have the same number of proton but incompatible number of neutrons. Isotopes have like chemical properties but antithetical physical properties. Ar = ________________________________________ Avogadros Law 1 mole of gas would fill up: 22.4 dm3 at STP (273K and 1atm) 24.0 dm3 at room condition (298K and 1atm) ______ __________________________________ Dilution MiVi = MfVf Titration Standard event: A consequence with known concentration. Primary Standard effect: A reliable, quickly quantified substance. Characteristics of Primary Standard Solution:  heights purity. Low reactivity.  richly solubility. High equivalent weight.

Examples: -Benzoic acid. -KBrO3 -Na2CO3 -NaCl ________________________________________ molecular pattern & Empirical Formula Empirical Formula: The formula of a chemical step up in its lowest integral ratio. molecular Formula: The authentic formula of a chemical compound. atomic STRUCTURE subatomic Partic les: Proton, p -Positively charged! -Forms nucleus with neutron. -Have almost akin throne with neutron. Neutron, n -Neutral. Electron, e -Negatively charged. -Occupy the shells around the nucleus. -Have peanut mass. ________________________________________ a = great deal number = Protons + Neutrons b =...If you want to get a expert essay, order it on our website: OrderEssay.net
