    EVIDENCE AS SUPPORTING THE REASON: In other arguments‚ evidence‚ rather than being the main reason‚ supports the reason in coming to some conclusion. Evidence usually refers to something seen‚ but evidence often refers to a collection of identical things that have been seen or heard‚ called data. “Statistical evidence” usually refers to the totaling of similar things or instances.

    I. Introduction There are two types of chemical reaction that occur one goes only in one direction and the other one is reversible. A reversible reaction is when a products starts to form the backward reaction starts where the products turns back to reactant molecules. When the rate of forward and backward reaction is already equal and the concentrations of the reactants and products no longer change with time we can say that chemical equilibrium is already achieved. A reaction is said to be at

    CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

    general relationship between light intensity and photosynthesis that could normally be seen had the experiment taken place without errors. The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis would take place in the algal balls. This would result in more CO2 being present because it wouldn’t be being used up during photosynthesis. The
