Virtual Chem Lab 6-2 & 6-3 Anonymous CHM/110 June 16‚ 2014 Zamir Deen Virtual Chem Lab 6-2 & 6-3 Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between

Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. Lately the production of biofuels has been discussed quiet frequently and many people have started focusing on the question if the production of biofuels actually is environmental friendly. Firstly‚ what is a biofuel? Biofuels refer to any solid‚ liquid or gas fuel that has been gotten from biomass. They produce biofuels by growing plants‚ growing sugar

self replicating molecules that made inheritance possible. 2. A.I. Oparin‚ and J.B.S. Haldane hypothesized a reducing environment. Stanley Miller and Harold Urey did lab experiments that showed that the abiotic synthesis of organic molecules in a reducing atmosphere is possible. These would occur in water for oceans. 3. The first genetic material was probably RNA. Early protobionts with self replicating‚ catalytic RNA would have been more effective at using resources and would have increased

In every chemical reaction‚ the starting materials (the substrate(s) in the case of enzymes) can take many different paths to forming products. For each path‚ there is an intermediate or transitional product between reactants and
