Objective/Question/Problem The objective of this project is to see if an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density

Lab Report # 11 By: Andrew Hoitt CHEM 105 Lab 11/29/2012 Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions

functions‚ but have not been successful in determining it purpose‚ although they have determined it is not used as a weapon nor is it used to gather food. Toucans primarily feed on fruit while snacking on an occasional lizard or insect. The bodies are compact as the wings are too. Scientists have determined that the wings were built to fly shorter distances than other birds in the rainforest. Toucans are often paired off or travel in small groups. Determining the sex of a toucan has been difficult

Riley Jefferson Block 7/8 October 8th 2012 Electrostatic Gedanken Lab Group Gamma Objective: The objective of this lab is to determine the charge on a pith ball. Hypothesis: I fully believe that the charge of the pith ball will be positive. The formula I will use to prove this is Coulomb’s Law‚ (Fe=(k*q1*q2) / r²). ‘Fe’ is equal to the electrostatic force between the spheres‚ measured in Newton’s. It is also a vector quantity‚ and it’s in absolute value. Secondly‚ ‘k’ is equal to Coulomb’s

Genes determine biological sex; assess the extent to which gender is bases on our genes. Although our chromosomal pairing will determine our sex (XX ’’ female and XY ’’ male)‚ this does not necessarily determine one’s gender. Gender is influenced at a pre-natal stage‚ via the release of testosterone from the gonads of an XY foetus. It is this testosterone release that sets in motion the train of events that lead to the eventual release of the other androgens from the pituitary gland. It is

I. Introduction The purpose of this experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble

Determining Causes and Effects of Lake Huron Brian Jones Weber English Composition 5/19/2013 In today’s Ecosystem there are so many factors of cause and effect of pollution in any areas of the world. Pollutants affect the air that keeps us breathing‚ the animals that we hunt or fish‚ and even the water that we drink. Food‚ water‚ and oxygen are the most important things we need in order to survive a world full of life. With this being said Lake Huron and the other Great Lakes are being extremely

Chemistry Lab Report example: Chemistry Laboratory Report (Magnesium Oxide) INTRODUCTION: As we learned before on how to determine the empirical formula of a compound based on the test and also chemical analysis on it. Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this

‘The extent to which volcanic processes represent hazards depends on where and when they occur’. Discuss this statement A hazard can be defined as a situation that poses a threat to life‚ health‚ property or the environment. The severity and type of volcanic hazards that occur are mainly dependent on the type of magma. Volcanic processes can be split into two categories – primary hazards and secondary hazards. The primary hazards that can occur are pyroclastic flows‚ lava flows‚ tephra and poisonous
