Imibuzo
Imibuzo evame ukubuzwa
Can the lab balance any chemical equation?
It balances any equation that has one correct set of whole-number coefficients, such as combustion and redox equations written with formulas, for example C3H8 + O2 -> CO2 + H2O.
Which data does it use?
Molar masses and standard reduction potentials match the values on the NSC Physical Sciences data sheets.
Does it name organic molecules?
Yes, for unbranched alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids and chloroalkanes with up to ten carbon atoms.
Ingabe kumahhala?
Yes. All labs on Biemann EduHub are free for learners, parents and teachers.
