Flow tube radius change has a direct effect on flow rate. As evidenced in this lab, when flow tube radius was…

Berlese Funnel Lab Report

Antonio Berryless was an Italian entomologist. He worked on pest insects (arthropods), usually those of fruit trees. Arthropods are the most successful animals on the planet. They make up over three. Fourths of all currently known living and fossil organisms. But, many still remained undocumented. Berryless funnels are used for extracting arthropods from soil and…

Voltaic Cell Lab Report

Voltaic cell is a device in which a redo reaction spontaneously occurs and produces an electric current. In order for the transfer of electrons in a redo reaction to produce an electric current and be useful, the electrons are made to pass through an external electrically conducting wire instead of being directly transferred between the…

Diffusion and Osmosis Lab Report

Osmosis is the usage of water from a region of high water concentration through a semi. Permeable membrane (Semi-permeable membranes are very thin layers of material which allow some things to pass through them but prevent other things from passing through,) to a region of low water concentration, This is seen in cell membranes. When…

Liquid Phase Chemical Reactors

It is also used in the laboratories in obtaining design, interpretation of rate of reaction and numerical treatment of kinetics experimental data for different types of reacting systems. The use of a batch reactor for the most part eliminates the effects due to fluid flow on the resulting reaction rates. Consequently, the data reflect the…

Cell Cycle Lab Report

Hypothesis Procedure: predict that all cells somatic will suffer all the division of mitosis multiple times n their lifetime; the product would be able to see the chromosomes in a stage of mitosis.
