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

Maria Reyes iLab‚ Week #3 ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The purpose of this lab was to determine the atomic weight of magnesium by measuring the amount of hydrogen gas evolved when hydrochloric acid reacted with magnesium. In order to measure the atomic weight I needed to measure the amount of the hydrogen gas that was evolved in reaction to the acid of the magnesium. The reaction used was: Mg + 2HCl --> H2 + Mg2+ (aq) + 2Cl- (aq). The major findings of this experiment were that

The Hydrochloric acid used in the experiment was a stock solution made by mixing HCl Acid and deionized water. HCl acid‚ historically called‚ muriatic acid or spirits of salt‚ hydrochloric acid is produced from sulfuric acid and common salt‚ NaCl (Princeton.edu). Since the early 1900 ’s‚ sodium

important in modern cell biology because all living cells are made up of chemicals and many chemical processes occur in various living organisms. Chemistry is the one science in which all the other sciences are based. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry - Why we breathe oxygen‚ how we make energy‚ elimination of waste products‚ cellular respiration‚ etc. All of these are based on how living organisms use chemistry to live.

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

Dear Friend‚ My biology teacher‚ Mrs. Anderson‚ asked me to send you a note about the importance of chemistry in biology. Chemistry is an important part of biology. Modern biology overlaps with chemistry in explaining the structure and function of all cellular processes at the molecular level. Chemical principles are important in modern cell biology because all living cells are made up of chemicals and many chemical processes occur in various living organisms. In biology you learn about living
