Ammonia, NH₃, is a colourless nitrogen compound with a characteristic pungent odour and basic properties.
Rule 1: The oxidation state of any uncombined or free element is always zero. Examples: Zn, Na, H₂, S₈, O₂ — oxidation state = 0 Rule 2: In…
CO2 from combustion and cement named. CH4 from wetlands and livestock named. H2O is a gas but not the 'control knob' humans turn first (school). Global warming…
A Venturi meter measures fluid flow using a wide section, a narrow throat and the pressure difference created by their different speeds.
A team of 4 from 6 boys and 5 girls with at least one girl: split cases 1,2,3,4 girls, or complement: all teams minus 4 boys. Pascal: nCr + nC(r-1) = (n+1)Cr…
