Experiment 2 Behavior of Gases PURPOSE This experiment has two parts. The purpose of part A of the experiment is to determine the atomic mass of a metallic element whereas the purpose of part B of the experiment is to determine the rate of diffusion of both gases hydrogen chloride and ammonia by measuring the distances travelled by the two gases in the same time period. For part A the reaction of the metal with the aqueous acid is as follows: M(s) + n H3O+ -----> M+n(aq) + n/2 H2(g) +

Chapter 6 – Properties of gases lecture notes 1. Gas phase Gases have neither definite shape or volume 1) volume changes with pressure 2) volume changes with temperature 3) gases are miscible 4) gases are generally MUCH less dense than liquids 2. Atmospheric pressure 1 atm = 760 torr (mm of Hg) F= ma F = force m = mass a = acceleration P = F/A - ma/A P = pressure

groups – clans) of ………. to ……….. animals. {Or ( It is a loner animal that doesn’t like to live in groups.)} The strongest (female-male) is the leader of the group. So‚ It leads them for their hunt or fighting. First of all‚ this animal uses different sounds to communicate together. For example‚ It moans to show it is unhappy. It sometimes howls to keep the group together. It usually trumpets when it is frightened or in danger. It also groans to warn its group of danger saying "Danger ahead".

How to Behave So Your Dog Behaves Chapter 4 Dr. Sophia Yin does a great job explaining the logic and reasoning behind why a dog acts the way it does (Yin‚ 2004). Her book is full of pictures and drawings that show in detail what she is talking about. Chapter four of her book is about learning to understand and read the body language of a dog. She teaches that through careful analysis and observation‚ a person can learn to quickly pick up on slight signals that communicate how a dog will respond to

As I entered Wal-Mart‚ the lights were bright but not gleaming. The employees were pleasant and working for the most part. Everything was easily accessible. I was not approached by anyone but if you needed help with finding something or you had a question about a product‚ there was staff available to assist. There were signs on the top of each isle which gives you an idea of the kind of things you can find in that particular isle. The store decor is not particularly pleasing to the eye but bearable

Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different temperatures

How is Research used in Psychology? * Research in Psychology as in all fields of science has two focuses of interest. * Basic Research = is concern with the quest for knowledge regardless of whether it has immediate practical value. * Applied Research = seeks to improve the human condition by discovering something that can be put to practical used. * When the scientist work‚ strive to find relationships between observable variables. For example‚ Robert Boyle found a direct relationship

developmental theories How children learn is very important in child care and in understanding how a child is to development. As children who are deprived of stimulation in early years develop slower‚ this statement opens up a massive debate which has been unanswered for years‚ the nature v nurture debate. There are 3 models of learning that cover all this debate and strive to be the correct theory they are the transmission model‚ the laissez-faire model and the constructivist view. How children learn

7.6 Summary 1. 7.6 Molecular Orbital Theory a. Intro i. Molecular orbital theory states that the atomic orbitals involved in bonding actually combine to form new orbitals that are the property of the entire molecule‚ rather than of the individual atoms forming the bonds. 1. The new orbitals are called molecular orbitals. ii. Electrons shared by atoms in a molecule reside in the molecular orbitals. iii. Molecular orbitals are like atomic orbitals
