Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different

Objective 1. To demonstrate the relationship between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas

Title: Double Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is

Defending The Double Wing Part I Rules for every player on the defense By Clay Kallam‚ Contributing Editor In 1994‚ coach Don Markham’s Bloomington High (Calif.) Bruins had a pretty good season. They went 14-0 and scored 880 points. Let’s review: 880 points. In one year. How did Markham do it...with an offense he devised that was a modern version of the Double Wing. It’s a highly effective offense featuring two tight ends‚ one fullback (right behind the quarterback) and two wingbacks…as in 880

FAMILY TRANSITIONS AND FAMILY MOVES The Double ABCX model provides a tool for assessing post-crisis variables in families. Interestingly‚ not all families go into crisis but instead they achieve a balance in functioning by either bonadapting or maladapting. While others may go into crisis and maladapt which was the situation with my family 30 years ago. A brief background of my family will provide some meaning to our family structure. My parents were both born and raised in Muncie‚ Indiana at a

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions
