    Experiment 7 INVESTIGATING STOICHIOMETRY WITH SODIUM SALTS OF CARBONIC ACID Introduction In this experiment we are going to get a better understanding of chemical stoichiometry. We are going to be reacting sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) with hydrochloric acid (HCl). To start off the mass of two unknown substances (being the sodium bicarbonate and sodium carbonate) will be taken. We will need to construct balanced equations for both of the reactants with the HCl and

    Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops

    The acid-fast stain is performed on samples to demonstrate the characteristic of acid fastness in certain bacteria. Acid fastness is a characteristic that is shared by just a few organisms‚ so staining to determine if organisms possess this trait is useful in microbial identification schemes. The Ziehl-Neelsen method has endured as a reliable and effective way to demonstrate the acid-fast bacteria.

    Biological Bases of Behavior Nervous System Made up of neurons‚ which are the nerve cells. These send electrical impulses to one another ( through a process known as firing) telling the body what to do. The parts of a neuron include: Cell Body (a.k.a. soma) – Main part of neuron; contains basic cell parts such as nucleus‚ ER‚ etc.; also has dendrites extending from it. Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension
