Desperate need of is mass conserved when 10 g of sodium hydroxide undergoes a chemical change during an interaction with 57 g of copper sulfate? use complete sentences to support your answer by explaining how this can be demonstrated. (i dont need to use mathematical support, just basic answers)

Conservation of mass states that "Mass cannot be created or destroyed".  In all reactions of a closed system, mass is always conserved.  So yes, the mass is conserved in this example

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
