    Introduction and Theory: A two dimensional object is a figure that has both width and height. Today in physics a two dimensional lab was done to decide the distance of an ice cream cone shooter. To do this‚ the formula (d=Ví t + (1/2) at^2) has to be implemented. I decided to make my Y equal to one meter‚ so my calculations would be easy to get. I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know

    Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

    Observation of Chemical Changes Purpose In this experiment‚ the student studied the composition of materials in a setting where the indications of chemical changes were safely observed. The changes observed consisted of bubble formation‚ colors‚ viscosity‚ and precipitate formation. Procedure Using a well plate: use a different well for each chemical combination. Two drops (unless otherwise noted) of each chemical in the combinations (below) should be placed in one well. A dark and light

    LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

    AP Chemistry Kinetics Lab Abstract: The purpose of this lab is to learn how to write law expressions‚ determine orders by graphs‚ and calculate rate constants. By determining the number of drops of sodium hypochlorite necessary to make a diluted food dye change to colorless in less than three minutes helps calculate the absorbance which can then be analyzed to find the pseudo rate constant and eventually leading to the rate constant and the rate law. The results show that the m and n are both 1st

    experiment was used to identify the chemical changes a substance undergoes by knowing some of its chemical properties like (Change in color‚ producing bubbles and gas‚ precipitation‚ conductivity). The aim of today’s lab was to help us identify different households and their components‚ they contained whether they were acid/ base‚ because most of the households are based on those solutions like (i.e. Acetic acid = Vinegar = CH3COOH can be used in cooking) or bases solutions like (bleach is applied for
