Introduction The objective of this experiment is to combine Magnesium (Mg) with hydrochloric acid (HCl) to determine the molar volume of hydrogen gas (H2) (converted to the molar volume at STP) and then‚ to compare obtained results with the molar volume of an ideal gas. To determine the measured molar volume of hydrogen gas‚ we are going to use this equation: The molar volume of the ideal gas will be determined by the equation ‚ where T = 237 K‚ P = 101.3 kPa. The hydrogen gas will be collected

Separation of Proteins and Mass Analysis Using SDS PAGE Biology 00-01L Abstract This experiment consisted of separating proteins into polypeptides using a method called SDS PAGE which is a type of electrophoresis. The polypeptides had different masses‚ so each polypeptide traveled a different distance and this was an essential part of the lab which demonstrated that there exists a relationship between the distance traveled by the protein and the mass of the protein. This relationship was graphed

Molar pregnancy is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus and converts a normal pregnancy into an abnormal one (which will fail to come to term). A molar pregnancy is a gestational trophoblastic disease[1] that grows into a mass in the uterus that has swollen chorionic villi. These villi grow in clusters that resemble grapes.[2] A molar pregnancy can develop when an egg that is missing its nucleus is fertilized and that may or may not contain fetal

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

Point load test Aim: To determine the strength characteristics of a rock using the point load test and visual judgement. Materials Loading device Loading frame Pump Ram Platens Rock Caliper Method (Standard‚ 2007) 1. Measure the dimensions of the rock which includes the diameter and length 2. Find the length to diameter ratio to determine which test will be used. If the ratio is greater than 1 use diametrical test. But if the ratio is between 0.6 and 1 use axial test 3. The axial

Lab 11: Animal Behavior Introduction Ethology is the study of animal behavior. There are two specific categories of behavior: learned ad innate. Orientation behaviors place the animal in their specific environment. Animals move away from sensory input in taxis where as behavior is the response to sensory input. Stimulus’ of light‚ heat‚ moisture‚ sound‚ or chemicals are mostly found in taxis. Kinesis is the movement that does not result in orientation with stimulus. When animals respond to each

Aim To investigate the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series. Introduction Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products. The molar heat of combustion of a substance is the quantity of heat liberated when one mole of that substance is burnt completely in air. In the case

Lab 7: Catalysts Introduction Pre-Lab Questions 1. What is a catalyst? An enzyme is a biological catalyst that speeds up chemical reactions in the body. 2. If you continue to add more catalyst will the speed of a reaction always continue to increase? Explain your answer. It will continue to speed up the reaction until there is more catalyst than the limiting reactant. 3. In this lab you will produce oxygen and water from hydrogen peroxide (H2O2). Write a balanced reaction equation for this reaction
