CHEM 104 Experiment 5: Buffers - Portage Learning Purpose: The purpose of this lab is to determine how buffers affect the pH of a solution in order to observe how a buffer is resistant to pH changes. Additionally, we determined how enzymes activity is affected by pH. Procedure: Part 1: Determine pH of sodium acetate in water & buffer 1. 2 pH electrodes are place in 2 separate beakers, one filled with tap water & one is filled with a pH 7 buffer (both have an approximate pH of 7) 2. A scoop of s...

How are organisms classified - Answer--organisms are organized -organisms acquire materials and energy -organisms reproduce -organisms respond to stimuli -organisms are homeostatic -organisms grow and develop -organisms have the capacity to adapt homeostasis - Answer-internal environment of an organism stays relatively constant natural selection - Answer-allows organisms to be better suited for their environment levels of biological organization - Answer-atom-molecule-cell-tissue-organ-...

temperature is related to KE how? temp is the average kinetic energy thermal energy is related to KE how? thermal energy is the total KE Brainpower enthalpy of fusion is ALWAYS greater than enthalpy of vaporization because? it has to break more bonds (solid --> liquid) the amount of heat depends on (2 factors) 1. the type of substance 2. the amount of the substance during a phase change does temperature change? NO if an archaebacerial species lives in a pool that is 0.01 M HCL wh...

1. What usually includes the entire golgi apparatus? a. The extracellular matrix. b. The lumen. c. The cytosol. d. The cytoplasm. 2. What is a common property of phosphoglycerides? a. They are symmetrically distributed on the lipid bilayer. b. They have a polar head group and one hydrocarbon tail. c. They are amphipathic. d. They have two hydrophilic tails. 3. Phosphatidylserine, a phosphoglyceride, is normally present on the cytosolic face of the cell membrane. However, when c...

CHEM 106.Lab Report 14: Acids, Bases, Salts and Buffers Acids and bases are pHun. Introduction:   The topic of acids and bases in chemistry is an interesting one to understand as it relates back to our daily lives. In this topic there are various terms that are of importance to learning the processes and underpinnings that make up this topic. These terms can be found below in the fundamental theories or laws section. In general acids can be identified by their sour taste and they can be...
