Properties of Gases General Chemistry 1 Lab 5 Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air

Experiment 8: Hydrogen Phosphate Buffer Systems Purpose The purpose of the lab was to create a buffer solution and observe the capacity of the phosphate buffer system. Also‚ the experiment was meant to provide experience with the calculations and mathematics involved in creating the buffer solution. Finally‚ the lab was designed to provide an insight and appreciation for the necessity and complexity of buffers in our physiology and in the environment. Procedure No deviations were made from

BIOLOGY 2020 LAB LAB 4 – Sensory Systems I. Vision 1. Know the types of photoreceptors in the retina. (Remember there are 3 different types of cones) 3 cones i. Blue- short ii. Green- Medium iii. Yellow-Red- Long 2. Why would near point accommodation change as you get older? (Think about what happens to the lens and the muscles of the eye with age) As you get older‚ the lens becomes hardened. The elasticity of the lens decreases dramatically with age‚ resulting in difficulty

During the experiments a few problems were encountered. One of the chemicals provided differed slightly from chemical description in the lab manual. The lab manual called for the chemical NH3 which is Ammonia. The chemical provided was an Aqueous Ammonia solution of NH4OH. When holding up the solution of AgNO3 and NH4OH to a light source for 5 minutes it was observed that no reactions took place despite the information contained in the lab manual. Also while testing the household chemical Brite‚ It was observed that the Bromthymol Blue changed to a green color that was not

A) January 18‚ 2011B) Empirical Formula C) The purpose is to determine the empirical formula of a metallic oxide. D) Pre Lab Questions: After heating the metal‚ the crucible and contents should mass less than it did before it was heated. This is because heating the crucible may rid of other residue that was left in it; bringing it a to a constant mass. A yellow flame will deposit soot on the crucible. This would be a problem because the soot left on the crucible would vary from our constant

Buffer Overflow Subscribe Hide Description Explain what buffer overflow attacks are and how they are created to attack our software. And‚ describe the best security measures you would recommend mitigate these buffer overflow attacks. Buffer overflow attacks occurs when hackers sending a large amount of data than the buffer was intended to hold‚ this large amount data immediately overwrite and corrupt other data in the buffer. Data contain codes to trigger specific actions that controls the program
