Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

Calorie Calculation Exercises 1. A serving of two cookies has 150 kcal and 12 grams of fat. What percentage of total calories is fat? 1) Divide fat calories by the total kilocalories 2) Fat = 9kcal/g 3) 12g x 9kcal/g = 108kcal/g 4) 108kcal / 150kcal = .72 5) .72 x 100 = 72% total calories from fat 2. How many grams of protein are in a 2400kcal diet with 15% of total kcal from protein? 1) Grams / total kcal = total percentage of kcal from protein 2) Protein

Hydraulics – CIVL 2130 Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies

administrator needs at least one week (minimum) to download‚ test‚ and install the patch. To calculate the Window of Vulnerability (WoV) for this security breach‚ the following timeline will be used as a guideline to determine the basis for calculation: However‚ first it is important to understand the variables considered in this timeline formula. The WoV is the period within which defensive measures are reduced‚ compromised‚ or lacking. The WoV covers
