Question: Give the chemical symbol or formula of:
Drill problems seen = 1 Correct responses = 0 Give Up count = 0 Time = 0.00 min
Formulas are case sensitive: Cobalt is Co, carbon monoxide is CO
- Do not worry about subscripts or superscrips in formulae: H2O not
H2O, and NH4+ not NH
- Problems are plucked at random from a database, and there is always the chance that the same question will be asked twice in succession...
