Physics Investigation A Formula 1 Margarine Tub Aim: I am going to investigate how the mass of a margarine tub affects the distance it can travel. The following Factors will affect the distance the tub can travel: · Surface area of the tub · Air Resistance · Force applied to propel tub · Length of elastic bands used to propel tub · Surface on which tub will travel Prediction I predict that as the mass of the tub increases‚ the distance the tub can travel will decrease. This

Formula 1: Delivering the F1 Experience 1. Give examples of needs‚ wants‚ and demands that F1 fans and sponsors demonstrate‚ differentiating each of these three concepts. What are the implications of each on F1’s actions? A lot of people‚ especially men‚ relieve their stresses through watching sports or playing sports. Through F1‚ fan and sponsors are able to relieve their stresses by meeting radical feelings such as fun‚ excitement and enjoyment. In addition‚ they want to fulfill their feelings

Melissa Carrithers 9-17-14 Period: 6 Determination of the Empirical Formula of Silver Oxide Purpose: To find the percent composition and empirical formula of silver oxide can then be calculated‚ based on combining the ratios of silver and oxygen in the reaction. Hypothesis: Silver oxide decomposes to silver metal and oxygen when strongly heated. Heating Silver oxide causes the oxygen to be driven off‚ leaving only the silver metal behind. The total mass of the products of a chemical reaction must

Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise

General Chemistry II Determining of the equilibrium constant for the formation of FeSCN2+ Introduction The objective of this experiment was to determine the equilibrium concentration and then determine Kc. A dilution calculation was formed to determine the concentration of SCN- and Fe(SCN)2+. Each cuvette was filled to the same volume and can be seen in table 1. Then the absorbances were recorded from each cuvette and can be seen in table 1. A Beer’s law plot was made from the data that was recorded

Shanel Warren Tiffany‚ Princess‚ and Wei October 2‚ 2013 Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to

Breastfeeding vs. Formula Bottle-feeding Every mother of a newborn baby must make a very personal decision when it comes to how they are going to feed their infant. I was faced with that decision 3 years ago when I had my first son who I named Ethen. It was one of the very hardest decisions I had to make. I had to consider all the good benefits of breast feeding as well as the benefits of formula bottle-feeding‚ but the good benefits of breastfeeding outnumbered the bottle feeding ones. I finally

theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds were mixed together
