Dˆe exemplo de 1a f´ormula ϕ do C´alculo Propxi6onal cujx conetivx estejam no conjunto {¬, ∧} e tal q ϕ ∧ (p0 ∨ p1) seja 1a contradi¸c˜ao.R:φ := (¬p0 ∧ ¬p1), x conectivx de φ perten100 a {¬, ∧} e φ ∧ (p0 ∨ p1)
...Chapter 1 – Atomic Structure & Matter
Atomic models: Dalton (solid sphere), Thomson (plum pudding, cathode ray), Rutherford (gold foil → nucleus), Bohr (planetary energy levels), Modern (wave mechanical/electron cloud)
Subatomic particles:
Proton: +1 charge, ~1 amu, nucleus
Neutron: 0 charge, ~1 amu, nucleus
Electron: −1 charge, ~0 amu, electron cloud
Isotopes: same element, different number of neutrons
Electron arrangement: ground state (lowest energy), excited state (

int main(CHEMISTRY
A physical change is a change in form or state where no new substance is formed, while a chemical change produces a new substance.
Clues of a chemical change include gas production, colour change, temperature change, formation of a precipitate, and light being produced.
Oxygen gas relights a glowing splint, carbon dioxide turns limewater cloudy, and hydrogen gas produces a popping sound with a burning splint.
The chemical families on the periodic table are alkali metals, alkaline
