Avogadro Constant: The amount of particles in 1 mole of any substance. 1 mole ≡ 6.02 × 1023 particles ________________________________________ Isotopes Isotopes: Atoms that have the same spot of proton but different number of neutrons. Isotopes have like chemic properties but different bodily properties. Ar = ________________________________________ Avogadros Law 1 mole of gas would consider up: 22.4 dm3 at s.t.p. (273K and 1atm) 24.0 dm3 at room pattern (298K and 1atm) ________________________________________ Dilution MiVi = MfVf Titration modular event: A solution with known concentration. aboriginal Standard effect: A reliable, readily quantified substance. Characteristics of Primary Standard Solution:  heights purity.  low-toned reactivity. High solubility. High uniform weight.

Examples: -Benzoic acid. -KBrO3 -Na2CO3 -NaCl ________________________________________ molecular Formula & a posteriori Formula Empirical Formula: The manifestation of a chemical heterogeneous in its lowest inherent ratio. molecular Formula: The unfeigned formula of a chemical compound. atomic STRUCTURE Subatomic Particles: Proton, p -Positively charged -Forms nucleus with neutron. -Have almost akin weed with neutron. Neutron, n -Neutral. Electron, e -Negatively charged. -Occupy the shells around the nucleus. -Have peanut mass. ________________________________________ a = Mass number = Protons + Neutrons b =...If you want to get a full essay, order it on our website: Ordercustompaper.com
