    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

    Rachel Smith Design Lab: Kinetics Lab Introduction: ! Background Information- Effervescent tablets reduce stomach acid and help treat upset stomachs. The familiar fizzing you hear when you drop an Alka-Seltzer tablet into a glass of water is the result of a chemical reaction. After dropping the tablet into the water‚ the reaction causes the solid tablet to become dissolved and releases tiny bubbles of carbon dioxide. This reduces the time it takes for the medicine to work as it does not need to dissolve

    In this lab‚ the pH of flat sprite and a fresh sprite are compared two ways: one way was to record the pH directly with a digital pH probe and the other was to calculate the concentration through titration. Because the reaction is a neutralization reaction‚ the concentration of can be calculated if the concentration of is known. At the end of the titration‚ the moles of will equal the moles of and the pH is expected to be greater than 7 because the found in sprite is weak and is a strong

    was soluble in water as well‚ but it had a very low melting point. All the substances except for sodium carbonate did not pass the requirements‚ and therefore sodium carbonate is the best possible substance. In order to prove this‚ I conducted a lab to determine the solubility‚ conductivity‚ and melting point of each substance. First‚ I made sure to obtain a Bunsen burner‚ evaporating dish‚ ethanol‚ the four substances‚ distilled water‚ conductivity probe‚ wash bottles‚ test tubes‚ and a beaker
