... We know the masses of the original washing soda and the soda that is left in the box after it has become partially dehydrated. We can find the chemical amount (moles) of the original washing soda, because we have a definite formula for it, and therefore we can calculate its molar mass (which, to mak ...

... Shapiro also critiqued some of the ‘prebiotic’ cytosine productions. He pointed out that both cyanoacetylene and cyanoacetaldehyde are produced in spark discharge experiments with an unlikely methane/nitrogen (CH4/N2) mixture. The classical Miller experiment used ammonia (NH3), but NH3, H2O and hydr ...
