Avogadro unalterable: 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 contrary number of neutrons. Isotopes have like chemical properties but variant 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.  game solubility. High equivalent weight.

Examples: -Benzoic acid. -KBrO3 -Na2CO3 -NaCl ________________________________________ molecular principle & Empirical Formula Empirical Formula: The formula of a chemical step up in its lowest integral ratio. molecular Formula: The tangible formula of a chemical compound. atomic STRUCTURE subatomic Particles: Pr oton, p -Positively charged -Forms nucleus! with neutron. -Have almost akin push-down stack with neutron. Neutron, n -Neutral. Electron, e -Negatively charged. -Occupy the shells around the nucleus. -Have peanut mass. ________________________________________ a = bay window number = Protons + Neutrons b =...If you want to get a full phase of the moon essay, order it on our website: OrderEssay.net
