Activity 1 1. Size and concentration of the solute 2. It was too large to pass‚ as predicted 3. I predicted that the glucose would diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚

The Business Balance Sheet completely outlines the company; it includes the breakdown of assets and liabilities. It then transfers that to the owner’s equity. It will show debts that need to be addressed‚ if sales or profits need to be increased and overall if the company is in good standing or not. I would use the return on owner’s equity financial ratio to interpret the data. Taking the income after taxes and dividing it by the owner’s equity. I would be aiming for a higher return.

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for

Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into
