How matter is conserved during chemical reactions?
All the atoms you had at first, are conserved in the new state also if arranged in a different way. Also the mass is the same also if may be that using or forming some gases, it can seem no true if you don't use a closed sistem
Old question, but still an absolute chemical principle....
Chemical reactions conserve TWO quantities: (i) mass; and (ii) charge. And so if you start with
Natural product chemists, who design and execute syntheses of complex biological molecules, will typically start a synthesis with KILOS of starting material. After a few steps they work with
