Lab Report: Stoichiometry Lab Oct. 27‚ 2011 Claire Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Newton’s First Law of Motion explains that objects in a state of uniform motion tends to remain in rest unless an external force is applied to it. Galileo’s concept of inertia is termed “Law of Inertia”. Law of Inertia‚ an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion‚ four forces on an aircraft; lift‚ weight‚ thrust‚ and a drag. Consider the motion of an aircraft at constant altitude‚ we can neglect the

Newton’s First Law of Motion states explains that a force is needed to change the motion of an object. It states that objects do not move or change their speed unless a force acts upon them. The first law applies to gymnastics in some areas‚ particularly on the bars and the balance beam. For example‚ on the bars when a gymnast performs a giant she is doing complete revolutions around the high bar while keeping her body straight. In order to begin this skill she had to apply some force to get into

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

around the user. It combats the effect of the separate inertia on ourselves‚ by making us a part of the car. Inertia refers to an objects tendency to maintain its state of rest or uniform motion unless acted upon by a force. Sir Isaac Newtons First Law of Motion revolves around Inertia. When the car is in motion‚ inertia wants it to keep going at that speed‚ but there are several forces acting on it‚ such as friction and air resistance. The engines power compensates for this energy loss. Anything

Fire Bug. Objective : To demonstrate the differences between physical and chemical changes while observing the laws of conservation of matter and energy. Procedure : Watch each part of the experimental demonstration and make predictions about what will happen in each scenario. 1. View the three scenarios listed below. You must observe and analyze these as part of the lab. The Iced Tea Debate The Salty Soup The Fire Bug 2 Use the DATA chart provided for recording observation

from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due to a force‚ of an object have different accelerations (∆v/∆t). The more massive the object is‚ the smaller its acceleration. Newton’s third law of force says that if two object interact‚ the force F12 exerted by object 1 on object 2 is equal

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules
